Lisebo Motjotji, Annah Moteetee, Lerato Seleteng-Kose — Wed, 01 Mar 2023 00:00:00 -0800

Background: Of the approximately 2,076 plant species occurring in Lesotho, about 355 are used for medicinal purposes. Many communities in the country, mainly in rural areas with limited access to health facilities, rely on traditional medicine as primary healthcare. Several publications provide helpful information on plants used for medicinal purposes in Lesotho. These include documentation of the plants, investigation of their therapeutic potential to provide scientific validation for their use, and conservation status. However, a synthesis of all the studies conducted so far has hitherto not been undertaken. The current study aimed to provide a systematic review of ethnomedicinal, pharmacological, and conservation studies undertaken on medicinal plants of Lesotho. The synthesis brings together published and unpublished literature sources, thus providing a comprehensive database for studies conducted on Lesotho medicinal plants. Furthermore, it identifies existing knowledge gaps on research that has been carried out on the species and thus provides opportunities for further research, especially in the search for new natural products.

Methods: Information was gathered from published and unpublished literature sources, with the earliest publication dating back to 1917. Information was gathered through keyword search using accessible literature sources from Google Scholar, Science Direct, Scopus and PubMed. Books, dissertations, theses, technical reports were also searched. Keywords used for the search were Lesotho, in conjunction with medicinal plant and traditional medicine. To be eligible for inclusion in the current review, a literature source was expected to have assessed ethnomedicinal use, biological/pharmacological activity (e.g., antimicrobial activity), phytochemistry, toxicology) or conservation status of any Lesotho plant species used in traditional medicine.

Results: A total of 116 records were identified, of which 76 were included in the review. Thirty-one ethnomedicinal, 14 pharmacological (nine antioxidant, three anti-inflammatory, five antimicrobial activities), six phytochemical, and 15 conservation studies on medicinal plants of Lesotho were scrutinized. It is important to note that some studies evaluated more than one pharmacological activity. Ethnomedicinal studies show that numerous plants are used for medicinal purposes in Lesotho, however studies to scientifically validate their traditional use has remained far behind.

Conclusion: Many of Lesotho’s important medicinal plants have been assessed for pharmacological activity, providing scientific proof for their use. However, there are numerous gaps in the number and type of pharmacological and phytochemical studies that have been conducted. These gaps offer endless opportunities for researchers working in these fields. In addition, the conservation status for most of these plants is unknown., therefore, a detailed red data listing of Lesotho plants, particularly those used in traditional medicine, is recommended.

Stephany Loor Constantine, Katherine Pazmiño Viteri, Karla Vizuete, Alexis Debut — Mon, 20 Feb 2023 00:00:00 -0800

Background: The growing demand for natural polymers useful for food and drug production has prompted the search for new plant sources to replace synthetic polymers. Unlike synthetic polymers, natural ones have advantages such as low toxicity, biocompatibility, and non-toxicity to the environment. Among the plant sources investigated as biopolymers, we find gums and mucilage, which have achieved a remarkable position in the additive market due to their applications in the paper, cosmetic, food, and pharmaceutical industries, to name a few. The genus Cordia L. is traditionally known for its medicinal use, however, in recent years the fruit mucilage has been studied as a biopolymer. This review aims to compile and analyze the research conducted with species of the genus Cordia L., especially the ones that studied the mucilage of its fruits, including the methods applied to obtain, identify, and characterize it. Besides, talking about its application in new groundbreaking fields.

Methods: Relevant information was selected from articles, books, theses, and patents published in databases such as Scopus, ScienceDirect, PubMed, Google Scholar, Google Patents, Patentscope, Patent Inspiration, and Espacenet.

Results: The research data showed that the biopolymer obtained from fruit mucilage of the genus has attractive physical and chemical properties, and may be suitable for the design of drugs, nanoparticles, coatings, and food products. In addition, specific studies revealed the presence of some flavonoids and terpenes as active ingredients of the genus Cordia L., which are associated with their ancestral medicinal use.

Conclusion: The possible use of mucilage of the genus Cordia L. is evidenced by its addition, substitution, or combination with other biopolymers to improve and design new products. Likewise, study alternatives are presented for countries where species of this genus are found and have not yet been considered for experimentation.

Keywords: mucilage, gum, biomaterials, pharmaceutical industry, food industry, medicinal use.

Background: Plant-based traditional or folk medicines hold a great deal of promise as the foundation for medications for different diseases. Hence, the purpose of the present study is to document and preserve traditional knowledge among the people of Lower Swat.

Methods: The field survey was conducted in 2018–2021, and 90 participants were interviewed using a semi-structured questionnaire. Information was collected predominantly from traditional practitioners, who are thought to have comparatively more knowledge and experience of using herbal medicine. During the discussions, notes were taken on the participants' demographics, plant names, plant parts used, and methods of herbal preparation. The collected data were analyzed through statistical indices in Microsoft Excel (2016).

Results: It was found that 118 species represented by 107 genera and 62 different families were used for various medicinal purposes. Our findings depicted that herbs (57.5%) were the most commonly used as compared to trees and shrubs, while leaves (37.06%) were commonly used plant part for therapeutic purposes. Lamiaceae (16 species) was the most important family, followed by Rosaceae and Asteraceae (7 species each). Among the modes of preparation, decoction, drying, heating, and infusion were the applied approaches. The data was also analyzed by using qualitative indices such as relative frequency of citation (RFC), use report (UR), fidelity level (FL) and use value (UV). The highest RFC (0.96) was recorded for Mentha spicata and Foeniculum vulgare while the highest FL for Berberis lycium (78%) and, Ajuga bracteosa (70%). The highest UR (4) was recorded for Ajuga parviflora, Pinus roxburghii and Pinus wallichiana. The highest UV (0.50) was recorded for Ziziphus oxyphylla.

Conclusions: The results of the present study reflect that medicinal plants are the most important source of health care in lower Swat. But in the absence of understanding and intuitive collective approaches, mainly therapeutic plants are overexploited in the area. There is a dire need for awareness about sustainable use of medicinal plants and threatened species in particular.

Potential of wild edible fruits for nutrition in indigenous communities of Northwest Himalaya, India

Mon, 16 Jan 2023 00:00:00 -0800

Background: In the rural areas of Himachal Pradesh, poor and tribal people depend on a variety of wild plants, animals, and fungi for their own consumption and for income generation. Despite their role in bridging periods of food shortages and providing dietary variety, most of wild edible plants are not accessed for nutritional potential. This is particularly true for the district of Kinnaur (a predominantly tribal area) of Himachal Pradesh. Hence, the present study was carried out to study the nutrient content of ten wild edible fruit species growing in the district of Kinnaur. The species included Berberis aristata, Elaeagnus umbellata, Hippophae salicifolia, Malus baccata, Prunus cornuta, Prunus persica, Pyrus pashia, Ramaria botrytis, Rosa webbiana and Viburnum cotinifolium.

Methods: The samples collected from the identified plants were cleaned, dried, powdered and stored in airtight containers for laboratory analysis. Fresh fruit pulp was used for measurement of pH, titratable acidity, total soluble solids (TSS) and ascorbic acid. Fresh weight of fruit pulp was recorded by using a digital balance and the samples were later oven dried (60^°C) for moisture content determination (AOAC, 2006). All the dried samples were pulverized in pestle and mortar into fine powder separately and stored in airtight containers, free from contamination till other parameters were determined. All the parameters were evaluated in triplicates, results were analyzed by using descriptive statistics and reported as mean ± standard error.

Results: The moisture content of the fruits varied from 58.76% to 89.75% while pH values ranged from 2.91 to 3.86. The crude protein of species varied between 0.38% - 4.58%. Prunus cornuta contained high amount of total soluble solids, TSS (18.53^oBrix). The acidity in the fruits ranged between 0.47-2.73%. The total carbohydrate content varied between 19.52% and 78.40%. The highest sugars (7.60%) were observed in the fruits of Viburnum cotinifolium. Total phenols ranged in between 0.26-1.47%. The maximum ascorbic acid content and antioxidant activity was recorded in fruits of Hippophae salicifolia. These wild edible plants had also significant amounts of minerals.

Conclusion: The study shows that these wild edible plant species are good sources of nutrition for rural population. Keeping in view the nutritional values and commercial potential, these important species need to be conserved in their natural habitats and should be included in traditional agricultural systems. Domestication of these species will not only improve the economic condition of the local people but also aid in the conservation of biodiversity.

Key words: Wild edible plants, nutritive values, domestication, conservation.

Background: Spathodea campanulata P. Beauv. (Bignoniaceae) is documented to have ethnobotanical potential worldwide, but knowledge about this useful tree to local communities is limited in Ghana. This study was aimed at evaluation of ethnobotanical knowledge of the utilization of S. campanulata among the local population in Ghana.

Methods: Data was collected through a semi-structured interviews with 193 participants in the Adaklu District of the Volta Region of Ghana. Ethnobotanical indices were used to quantitatively determine the most culturally important S. campanulata plant parts using the ethnobotanyR package.

Results: A total of 25 applications grouped into six use categories from seven S. campanulata parts were observed in this study. The primary use category was material, followed by fuel, medicine, environmental, food additive, and food. Anemia had the highest frequency of mentions, followed by firewood and dyeing of cloth, construction, furniture, and charcoal. The wood had the highest use reports (UR) and cultural importance (CI), while stem bark had the highest number of uses (NU) and cultural value index (CVe).

Conclusion: The study showed that the applications and use categories were influenced by the rural nature of communities and lack of availability of services. This study revealed a high-fidelity level for the S. campanulata stem bark to treat anemia, a common ailment in the study region. The study suggests increasing awareness for better promotion and valorization of S. campanulata in Ghana as a source of fuel wood and medicinal purposes.

Medicinal plants and their use by an ethnic minority Jirel in Dolakha district, Central Nepal

Sangram Karki, Ashis Prakriti Dhital, Yadav Uprety, Suresh Kumar Ghimire — Thu, 16 Feb 2023 00:00:00 -0800

Background: Plants are important source of traditional medicine and are used widely in the primary healthcare of indigenous peoples and local communities. Despite a considerable number of ethnobotanical studies in Nepal, there are still several regions to be explored and scientifically document the traditional uses of medicinal plants. This study was conducted in one of such areas in the Dolakha district of central Nepal with the indigenous Jirel community.

Methods: Ethnobotanical information was collected using guided field walks, semi-structured interviews, and key informant interviews with traditional herbalists and elderly men and women of the Jirel community. The data were analyzed both qualitatively and quantitatively using use value (UV), informant consensus factor (FIC), and preference ranking.

Results: This study recorded 111 medicinal plant species belonging to 103 genera that were used to treat 11 health disorders. Families such as Asteraceae, Lamiaceae, and Rosaceae have contributed a higher number of species of the total species recorded. Gastrointestinal disorders, skeleton-muscular disorders, fever, headache and cut and wounds were the common health problems among the Jirel people. Roots were mostly used for the preparation of remedies, followed by leaves and fruits. The informant consensus factor (FIC) ranges from 0.74 to 0.93 with an average of 0.87. Paris polyphylla, Cirsium verutum, and Astilbe rivularis have the highest use values of 0.98, 0.96 and 0.92 respectively. This research finds that traditional knowledge about the use of medicinal plants is more centered on Jirel herbal healers (Lama/Jhakris) and elderly people than youths. Similarly, knowledge transmission routes are mainly from parents to their eldest child. Over-harvesting, premature harvesting, and deforestation were found as major threats to medicinal plants. Furthermore, the abandonment of traditional herbal practices, the loss of traditional healers, and the youth’s unwillingness to traditional healing systems were threats to the ethnobotanical knowledge of medicinal plants in the Jirel community.

Conclusions: The diversity of medicinal plants in the area and the associated indigenous knowledge of use among Jirel people have contributed significantly to their healthcare system. The medicinal uses of the documented species provide the primary information for further ethnopharmacological studies and conservation of most useful species in the study area.

New evidence regarding the role of previous disease experiences on people’s knowledge and learning of medicinal plants and biomedical drugs

Sâmara da Silva Santos, Flávia Rosa Santoro, Washington Soares Ferreira Júnior — Sun, 12 Mar 2023 00:00:00 -0800

Background: What factors influence the knowledge and learning of medicinal plants and biomedical drugs? We investigated this question in a context of intermedicality, exploring previous experiences and the duration of diseases at the individual, family, and community levels.

Methods: We conducted our study in a rural community in Northeast Brazil. We use individual semi-structured interviews to gather information on people’s knowledge and learning of medicinal plants and biomedical medications, as well as their prior experiences perceived with diseases at different levels (individual, family, community) and their duration perceived.

Results: The knowledge of medicinal plants can be explained mainly by the previous experience of the disease in the community and the family. For medicinal plant learning in one year, only the previous experience in the community is relevant, but it had a negative influence. Regarding the knowledge of biomedical drugs, we observed positive influence of previous experiences in the family and community and negative influence of the diseases’ duration. Finally, none of the predictor variables explained the learning of knowledge of drugs of biomedical origin.

Conclusions: The present study suggests important mechanisms that regulate the knowledge and learning of new treatments (medicinal plants and medicines of biomedical origin) in medical systems.

Molecular and morphological analyses of plants with ethnomedicinal uses in northeastern Peru

Daniel Tineo, Martha S. Calderon, Danilo E. Bustamante, Manuel Oliva — Tue, 17 Jan 2023 00:00:00 -0800

Background: In Peru, ethnomedicinal plants have not been extensively assessed in the current context of DNA-based techniques. In the Amazonas region, medicinal plants use for diarrhea and fever treatment are mainly known by local or traditional names, while their phenotypic plasticity limits their proper morphological identification.

Methods: In this regard, selected plants with ethnomedicinal uses in the Amazonas region were confirmed and characterized using morphology and multilocus phylogenies based on three molecular markers (ITS, matK, and rbcL).

Results: This study reported four species with ethnomedicinal uses [Disciphania ernstii (Menispermaceae), Psidium fulvum (Myrtaceae), Styloceras penninervium (Buxaceae), Ugni myricoides (Myrtaceae)] distributed in humid forest, at 1,000–3,800 masl in the Amazonas region. The genetic markers that showed better resolution to distinguish species of the genera were ITS (Disciphania) and matK (Psidium, Ugni, and Styloceras).

Conclusion: An initial screening regarding the diversity of plants with ethnomedicinal uses in the Amazonas region was needed and should include DNA-based techniques using these molecular markers to correctly identify them. This approach will facilitate further evaluation of the ancestral knowledge on the use of medicinal plants in Peru.

Diversity of wild edible plants and fungi consumed by semi-nomadic Gaddi and Sippi tribes in Doda district of Union Territory of Jammu and Kashmir

B.P. Singh, Yumnam Devashree, Vikas Sharna, R.K. Manhas — Fri, 26 May 2023 00:00:00 -0700

Background: Consumption of Wild edible plants (WEPs) is a cultural heritage of tribal and other rural communities. WEPs have a vital role to play not only in ensuring nutritional security and combating malnutrition but also in meeting medicinal requirements, income generation for these communities, and crop improvement through plant breeding programmes. The present study was conducted with the objective of documenting traditional knowledge and practices of utilizing WEPs by Gaddi and Sippi tribes of Doda district of Union Territory of Jammu and Kashmir (JKUT).

Methods: An ethnobotanical survey was conducted in five villages of Doda district (JKUT) inhabited by Gaddi and Sippi tribes. The random sampling method was used for the selection of informants. The data was collected through interviews and focused group discussion with the informants as per semi-structured schedules. The uses of WEPs were recorded as use-reports, and culture importance value (CI) and factor informant consensus (F_ic) were calculated from these values.

Results: A total of 77 species spread across 58 genera and 39 families were reported by 203 informants (148 males and 55 females). Angiosperms represented by 63 species were the major source of forest foods followed by 9 fungal species. WEPs with the highest number of species were vegetables (34 species), and fruits and nutraceuticals (27 species each). The most important species on the basis of CI were Geopora arenicola (Lev.) Kers. (CI = 0.66), Geopora sumneriana (Cooke) M. Torre. (0.60), Diplazium esculentum (Retz.) Sw. (0.56), Diplazium frondosum C. Chr. (0.54), and Mentha arvensis C. Presl. (0.52). Values of F_ic ranged between 0.91 (nutraceuticals) and 0.99 (cooked WEPs). The knowledge of WEPs significantly increased with age and decreased with education level of the informants.

Conclusions: The Gaddi and Sippi tribes are utilizing a good number of WEPs, and more importantly they exchange this information among themselves. As far as future prospects of this study are concerned, nutritional and nutraceutical properties of species like Anethum sowa, Arisaema propinquum, Diplazium frondosum, Dipsacus inermis, Elaeagnus umbellate, Elwendia persica, Geopora sumneriana, Impatiens glandulifera, Morchella crassipes, Morchella conica, Prinsepia utilis, Sageretia thea, Solanum villosum, Thymus mongolicus, and Ziziphus oxyphylla may be studied to make them popular amongst masses.

Mon, 16 Jan 2023 00:00:00 -0800

Background: The present study encompassed a highly traded medicinal plant Viola odorata L. (Violaceae) for detailed Light and Scanning Electron Microscopy, ethnobotany and phytochemical evaluation. Phytochemical evaluation included ascorbic acid, nutritional, and phytochemical profile, and essential and fixed oil study. Even though each feature has its own limited taxonomic value but collectively these characteristics may be systematically important especially for the discrimination and identification of complex and problematic taxa.

Methods: The aim was to study microscopy, histology and phytochemical composition of Viola odorata on the basis of ethnobotanical information cited in the literature. Methods: The microscopy, and phytochemical composition of V. odorata was studied using standard methods.

Results: Anatomy of the plant parts depicted dicot histology. Stomatal study under LM and SEM, revealed the presence of diacytic and anisocytic type of stomata. Stomata were numerous on the lower epidermis of the leaf. SEM of the powder drug showed the presence of trichomes, calcium-oxalate crystals, pitted vessels, fibers, trichomes, pollen grains, parenchyma cells, pith cells and root hair, but some unknown tissues were also seen. Ascorbic acid, nutritional, and phytochemical profile was investigated according to the standard methods. Different parts of the plant contained various chemical constituents such as alkaloids, mucilage, anthraquninone, saponins, tannins, fats and oil, protein and starch. Quantification of phytochemicals revealed mucilage and tannins to be the highest as compared to saponins and alkaloids. Leaves had 0.00143 % essential oil and 0.396 % fixed oil. Ascorbic acid, nutritional, and phytochemical profile, and oil study revealed vitamin C, proximate and phytochemical composition of V. odorata. Conclusion: Overall, this study can be helpful for plant taxonomists to further analyze the species for phytochemical isolation. This will improve the regulatory process and reduce the risk of a quality breach.

Background: Due to the lack of primary health facilities and poor economic situation, the traditional use of plants for curing diseases is very common in rural areas of developing countries across the globe. The present study aimed to explore people-plant interaction and the conservation status of Jelar Valley, during 2014-2017.

Objectives: The main goals of this research were; to enlist the medicinal flora; to gather indigenous knowledge concerning the medicinal plants; to assess the conservation status of the medicinal flora area.

Methods: To collect information on ethno-botanical uses of plant species, a semi- structure questionnaire was prepared, and information was collected from local knowledgeable peoples of the area including male and female as well from local people. A total of 135 informants were interviewed regarding ethno-medicinal uses of the plants found in the area. The collected plants were classified into various used categories on the basis of information on their ethno-botanical uses. The relative frequency of citation, family importance values and conservation status were also calculated.

Results: In the present study, checklist of 83 plants was prepared and also determined its conservation status. The results revealed that of the 83 medicinal species (62.7%) were herbs, (21.7%) were trees and the remaining (15.7%) species belonged to shrubs. The results showed that mostly the species were used as a whole plant (21.7%), followed by leaves (25.3%), leaves and fruit (9.6%), Based on Family Importance Value (FIV) the best represented used family was Lamiaceae (91.11 %), followed by Asteraceae, while the highest Relative Frequency Citations was recorded for Mentha longifolia (0.266) followed by Olea ferruginea (0.259). The conservation status of medicinal flora revealed that Melia azedarach was found endangered, 35 (42%) species were rare, 15 (18%) species infrequent and 32 (39%) species were recorded as vulnerable in the area. Following the International Union for Conservation of Nature criteria 2001 for conservation none of the population was declared in the dominant category.

Conclusion: The study showed that the area has a great diversity of plants used for different ailments. The plants' utilization and unsustainable use of plants increase day by day for different purposes. The diseases are increasing day by day; they may cause a great threat to the flora of the Valley. The survey aims to make people aware of valuable plants and to protect them from extinction. The old people are aware of the accurate knowledge of medicinal plants and are needed to preserve this knowledge for the next generation.

Irfan Ali Shah, Tanvir Burni, Lal Badshah, Noor Ul Uza — Thu, 16 Mar 2023 00:00:00 -0700

Background: People still use plant-based medicine for their basic healthcare requirements despite having easy access to contemporary medications. Individuals are more dependent on natural remedies, especially in rural areas. In Garyaum, North Waziristan, Pakistan, this study intends to investigate the key native plants utilized in medicine and their applications for treating various illnesses.

Objectives: The objectives of this study was to: (1) conduct a systematic examination of the wild plants utilized by the inhabitants of the study area; (2) collect indigenous knowledge concerning wild plants; (3) assess species with considerable cultural importance to the Garyaum inhabitants; and (4) document the conservation status of the collected plants in study area.

Methods: Ethnobotanical data based on sociodemographic characteristics were collected using the protocol of (Martin 1995). Techniques included direct led field walks, focus groups, and semi-structured interviews. 95 participants including 81 men and 14 women were interviewed. Quantitative approaches, such as relative frequency citation (RFC), use value (UV), and fidelity level (FL) were also conducted.

Results: The participants reported a total of 66 plant species, belonging to 49 genera and 28 families. Of the total reported plants, 47 were fodder species, 35 were medicinal species, 14 were timber species, 20 were fuel species, 11 were fruits species, 7 was vegetable species, 2 were condiment species, 9 were thatching species, 3 were ornamental species while 3 were poisonous in nature. The current findings revealed 45 species (68.18 %) as vulnerable, 9 species (13.63 %) as rare, 8 species (12.12 %) as endangered and 4 species (6.06 %) was found infrequent. None of the species was ranked in the dominant category (IUCN 2001) which clearly described the unpleasant situation of the local flora.

Conclusion: It is concluded that local people still rely on plant-based medication for their basic medical requirements. The vast majority of the species are utilized as fuel, wood, and fodder. In addition, plant diversity is diminishing as a result of many anthropogenic influences, infrastructural expansion, and climate change as well. Hence, proper identification and cultivation of significant medicinal and aromatic plants, as well as appropriate conservation and management techniques, are urgently needed in the research region. And the value of floral diversity and conservation must be entrenched in local inhabitants' children.

Adi Bejo Suwardi, Syamsuardi, Erizal Mukhtar, Nurainas — Wed, 01 Feb 2023 00:00:00 -0800

Background: Wild edible fruit plant species (WEFs) contribute significantly to human well-being. These plants have a high nutritional value and are a source of novel alleles/genes that are important in developing new and improved crop cultivars to promote sustainable food security. However, most WEFs are less well-known and underutilized. This study aimed to investigate wild edible fruit species diversity and their potential in the Bengkulu region, Indonesia.

Methods: The ethnobotanical study was carried out in eight villages from four districts of Bengkulu province, Indonesia, i.e. Mukomuko, Lebong, Rejang Lebong, and Bengkulu Selatan. The ethnobotanical survey was carried out from July to September 2022 and included 383 randomly selected respondents. The ethnobotanical investigation uses semi-structured questionnaires to gather information on the traditional knowledge of WEFs. Plant specimens were collected and identified in herbarium ANDA, Universitas Andalas.

Results: A total of 73 wild edible fruit plant species belonging to 37 genera and 26 families were recorded in the study area. Most of the plant species were trees (87.7%), followed by shrubs (5.5%), climbers (4.1%), and herbs (2.7%). Forty-eight (79.5%) species were discovered in the forest, 7 (9.6%) in the farmlands, and 8 (11%) in both the forest and the farmlands. WEFs are mostly consumed as food. Artocarpus integer, Mangifera odorata, Pometia pinnata, Flacourtia rukam, Durio oxleyanus, Baccaurea racemosa, Bellucia pentamera, Baccaurea macrocarpa, Baccaurea polyneura, and Mangifera foetida. Artocarpus integer are the most preferred WEFs by their taste quality. Besides foods, WEFs have multi purposes including as traditional medicine, construction, agricultural tools, fuelwood, and fodder. Indigenous knowledge of WEFs was significantly associated with districts, age groups, and educational levels.

Conclusion: Bengkulu has a diverse range of WEFs, but only a small proportion has been used by local people, particularly as food. Promotion and domestication of WEFs should be a primary concern in Bengkulu in order to take advantage of their nutritional value and potential economic value. Moreover, integrating knowledge related to WEFs into the educational curriculum is critical for educating the next generation regarding the potential of WEFs in the future.

Methods: Assessment of ethnobotanical use of M. oleifera was carried out using questionnaire survey and informal meetings while the laboratory experiments were performed to appraise the chemical constituents and their activities. The crude methanolic extract of different plant parts of M. oleifera was prepared by cold percolation method and then qualitative phytochemical screening was done following standard protocols. The antibacterial activities of different plant parts were tested using agar-well diffusion method against five different human pathogenic bacteria namely Bacillus subtilis, Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa and Staphylococcus aureus.

Results: The plant is being used in 16 districts of lowland Tarai of Nepal for the treatment of 22 ailments including six potentially bacterial ailments: inflammation, tuberculosis, hysteria, diabetes, piles and tumors. Of the five useful plant parts, leaf, root, fruit/seed and bark were frequently harvested while the flower was least used. Analogous to the ethnomedicinal uses, phytochemical compounds of the plant, flavonoids, tannins, phenols, and glycosides exhibited the strong antibacterial activities. The extract from bark showed the higher zone of inhibition followed by leaf and seed, revealing their high potentials for pharmacology. Bark showed the high antibacterial activity against B. subtilis followed by leaf, whereas seed shows its best against S. aureus and root against E. coli.

Conclusions: M. oleifera is a promising medicinal plant based on our ethnobotanical survey and laboratory assessment. More research on its ethnomedicinal and biochemical capabilities is needed. Documentation and comparative assessment of traditional knowledge and phytochemical findings might lead a consented and conscientious avenue for bio-prospecting and novel drug discovery.

Resilience processes and positioning of agroecological farmers in an urban horticultural fair in northwest Patagonia

Ana H Ladio, Melisa Longo, Soledad Molares — Sat, 29 Apr 2023 00:00:00 -0700

Background: Horticultural fairs are spaces that promote regional agrobiodiversity, transmitting and recreating multiple knowledge and emotions between horticulturists and customers. The adaptive processes by which fairs are sustained over time in the face of socio-economic, climatic, and sanitary changes are still little known. Considering the principles of socio-environmental resilience, the aims of this research were: 1) to analyze the positionings of horticulturists that favor the process of resilience in the Free Fair of Family Farmers from Nahuel Huapi, San Carlos de Bariloche (Patagonia, Argentina) and 2) to reflect on the vulnerabilities and challenges faced by this fair for its sustainability over time.

Methods: A qualitative study was carried out that included interviews, participant observation, and virtual ethnography.

Results: One hundred and eighty-six ethnospecies, mostly of exotic origin (99%) are part of the agrobiodiversity of the fair. The main principles that foster the resilience of the fair are: high agrobiodiversity and functional redundancy that reflect and promote local food customs; learning and connectivity for innovation and information exchange; and cooperation and adaptive systemic thinking based on experiences, attachment to the land, and reciprocity. The affective dimension crosses each of these principles, strengthening the cultural fabric of horticulturists and customers. However, the economic and cultural viability of the fair is uncertain, mainly due to the drastic socio-environmental changes that the region is experiencing.

Conclusions: To reduce the vulnerabilities of the fair, it will be necessary to strengthen the principles mentioned above and to increase the participation of the broader levels of governance (technical and governmental sectors).

Keywords: Agrobiodiversity, urban contexts, food sovereignty, socio-environmental resilience, vulnerability.

Digestive plants of the Patagonian steppe: multidimensional variables that affect their knowledge and use

Soledad Molares, María Laura Ciampagna, Ana Ladio — Wed, 22 Feb 2023 00:00:00 -0800

Background: In a rural Mapuche community of the Patagonian steppe (Chubut, Argentina), we analyzed how the use and popularity of digestive plants are affected by their aroma, the presence of dual medicinal-edible uses, their digestive versatility, biogeographical origin and accessibility.

Methods: Free listing and in-depth interviews were conducted with 25 collaborators, complemented with participant observation and walks in the field. Quantitative indices, non-parametric methods (Binomial and Chi-square tests, p < 0, 05) and generalized linear models (GLM, Omnibus test, p < 0, 05) were performed.

Results: Local collaborators use 61 digestive plants, including a similar number of native and exotic species. Most are used for only one type of digestive use, are very accessible and have aroma. There are as many species with dual use as without dual use. Exotic species generally have more aroma than native ones. Only exotic species are highly accessible. Species with dual uses are mainly used as condiments. Digestive-only species could or could not have aroma. The popularity of species is only affected by their digestive versatility and aroma, mainly for exotic ones.

Conclusions: Local pharmacopoeia reflects aspects that account for its cultural resilience, including a high richness of native and exotic digestive plants, many of which are used for specific ailments. The species have been selected from the joint evaluation of biophysical and sociocultural variables that influence their knowledge and forms of use. These variables and perceptions would also allow diversification in response to changes, forming part of a bio-cultural legacy unique to Patagonia.

Background: To the best of our knowledge, this is the first quantitative and conservation ethnomedicinal evaluation of the Van Gujjar Tribe inhabited in the Delhi-Dehradun Highway Shivalik hills Belt (DHSB). The study area is situated adjacent to biodiversity hotspot Rajaji National Park, Uttarakhand, which is an important part of Himalayan systems. The area is ecologically sensitive, increasing anthropogenic disturbance and overexploitation of medicinal herbs is also major concern. So, along with conventional ethnobotanical studies, conservation analysis of the area is important.

Methods: This ethnomedicinal study comprised extensive field surveys and repetitive interviews of 120 informants of the Van Gujjar tribe with different social and educational backgrounds. Procured data were analyzed using three different quantitative indices, i.e. the relative frequency of citations (RFC), informant consensus factor (ICF), and the fidelity level (FL%). Collected plant samples were identified by relevant flora literature and online plant databases. Identified species conservation status was derived from The IUCN online database.

Results: A total of 71 medicinal plant species from 67 genera and 41 families were documented from the study area. The most frequently used species, Zingiber officinale Azadirachta indica A. Juss, and Ageratum conyzoides L. were employed for multiple health issues, mainly for digestive and respiratory disorders. The highest RFC values are Z. officinale (RFC = 1.0), A. indica A. Juss. (0.99) and A. conyzoides L. (0.92. FL% of these species were 96%, 90% and 83 % viz. The highest ICF value is 0.98, which shares dental & gum problems, digestive disorders and wounds categories. The IUCN status of 71 reported medicinal plant species indicated 28.1 % plant species were least concerned, 4.2 % critically endangered (Chlorophytum borivilianum,Commiphora wightii, Nardostachys jatamansi ), 1.4 % near threatened and 1.4 % endangered, 2.8 % Data Deficient, while 61.9 % species status remained unknown as currently not available in IUCN Red data list. Highly utilized species IUCN status however under ‘least concerned’ category.

Conclusions: The study aids medicinal plant species data with current conservation status in the Delhi-Dehradun Highway Shivalik hills Belt. Medicinal plant species such as Chlorophytum borivilianum, Commiphora wightii, and Nardostachys jatamansi are critically endangered and others could be prone due to overexploitation. The present data could help to fill the previous conservation and quantitative ethnobotanical studies gaps in the study area.

Thu, 25 May 2023 00:00:00 -0700

Background: Wild herbaceous food species are declining throughout the Sahel region, particularly in the south-eastern corner of Niger, where settlements of thousands of refugees from Boko Haram, in addition to the native people, generate high pressure on the herbaceous food species. The objective of this study is to assess the use of wild herbaceous food plants in two departments in the Lake Chad Basin.

Methods: Ethnobotanical surveys were conducted with 270 informants asked about their use of these plants for food including parts consumed, food categories, economic value and impact of exploitation.

Results: A total of 32 wild herbaceous species, mainly from the family Poaceae (21.8%) and dominated by the life form Therophytes (43.7%), were cited. According to the respondents, the most consumed parts were the leaves with 51.2% and 41.3% of the citations in Mainé Soroa and N'Guigmi, respectively. Seeds were cited by 26.8% of the informants in Mainé Soroa and 30.7% in N’Guigmi. Fruits were cited by 19.2% and 26.2% in Mainé Soroa and N'Guigmi, respectively. The least consumed parts were roots and flowers. The species preference depends on the ethnic group. Refugees who had recently settled in the area stood out with a consumption of other species than the native people. Informants from Mainé Soroa and N’Guigmi stated that 52% and 44% of the species, respectively, were becoming increasingly scarce. The main causes of the degradation of these resources were agriculture, drought and overexploitation.

Conclusions: In general wild herbaceous food resources play a very important role in the Lake Chad Basin, where people live insecure lives.

Methods: Ethnobotanical data were analyzed using quantitative tools, i.e., Relative frequency citation (RFC), use value (UV), and fidelity level (FL).

Results: 102 participants including 75 men and 27 women were interviewed. The participants reported a total of 68 plant species, belonging to 57 genera and 19 families. There was 1 family of pteridophytes (1 species), 1 family of gymnosperms (4 species) and 63 species belonging to 17 families of angiosperms. Of the total reported plants, 38 were fodder species, 37 were medicinal species, 5 were timber species, 9 were fuel species, 8 were fruits species, 1 was vegetable species, 5 were condiment species, 2 were thatching species, 9 were ornamental species while none of the species was poisonous in nature. Conservation status revealed that 49 species (72.05 %) were vulnerable, 12 species (17.64 %) were rare, 6 species (8.82 %) were endangered, and 1 species (1.47 %) was found infrequent.

Conclusion: The current study showed the majority of the species were used as fuel wood, medicines, and fodder. As most plant species have significant curative properties, a rotational and moderate grazing system is required to conserve the plants. Local residents must inculcate in their children the importance of floral diversity and conservation.

Ethnobotanical research under the COVID-19 pandemic: assessing a remote method for documenting Indigenous plant-related knowledge

Thu, 25 May 2023 00:00:00 -0700

Background: In response to the limitations on fieldwork imposed by the COVID-19 pandemic, we describe and assess a remote method for documenting plant-related knowledge, using smartphones that requires no in-person interaction between an on-site Indigenous community and off-site researchers.

Methods: The on-site team identified the Indigenous taxa, created equivalents of photo vouchers, and recorded their names and uses as voice messages using a smartphone, thereby learning about plants from one another. They then sent the data using WhatsApp messages to the off-site team, who identified the botanical names of the taxa, and analyzed the plant-related knowledge.

Results: We assess the remote, collaborative, and transdisciplinary quality of the method, factoring in communication, audiovisual documentation, species identification, knowledge exchange, logistics, and ethics. Despite the problems we experienced with identifying taxa growing in high forest and translation issues that complicated the documentation of plant uses, the method was on the whole a success. It allowed the on-site team to activate their passive knowledge of their language and share their knowledge with their relatives. The off-site team identified 57% of the recorded 54 taxa to species level and documented their names and uses as primary audio data, which keep on enhancing the quality of the documentation.

Conclusions: Smartphones can be used as research tools during periods of restricted physical access, but also to extend research beyond the fleeting field visits and to elevate the empirical standard of ethnobotany when it comes to language data. We see such remote research solutions not as replacements for in-person collaborations, but as valid and dynamically evolving research methods in their own right.

Uses of Oldeania alpina (K. Schum.) Stapleton (Poaceae) and local perceptions of its spatio-temporal dynamics in Lubero cool highlands region (DR Congo)

Tue, 17 Jan 2023 00:00:00 -0800

Background: In the Democratic Republic of Congo (DR Congo), Oldeania alpina (K. Schum.) Stapleton provides multiple goods and services to rural populations and is the keystone species of mountain forest ecosystems, most of which are in a very advanced state of degradation. The present study was carried out in Lubero cool highlands region, in the North-East of the DR Congo. It aims to highlight the knowledge of local populations on the uses of O. alpina as well as their perceptions of the spatio-temporal dynamics of this high-altitude bamboo species.

Methods: Ethnobotanical surveys were conducted in five villages of the study area through semi-structured individual interviews and focus groups with 245 people. The different forms of use of O. alpina organs and the local perceptions of its spatio-temporal dynamics were the key axes of the surveys. The software R version 4.1.5 was used to calculate the ethnobotanical indices and to carry out static analyses of the data.

Results: The results showed that O. alpina is well known by the populations of the study area and is solicited in seven main categories of use, namely: fuelwood (22.5 %), construction (22 %), handicrafts (17 %), agriculture (14.5 %), pharmacopoeia (14 %), worship (8 %) and food (2 %). For these uses, the populations solicit the following organs: culms (59.2 %), blades (12.24 %), shoots (10.54 %), rhizomes (6.78 %), sheaths (6.56 %) and straw (4.68 %). Also, for the populations of the study area, the bamboo groves of O. alpina are in a regressive spatio-temporal dynamics.

Conclusion: In Lubero cool highlands region, O. alpina is in constant degradation due to uncontrolled human exploitation. The results of this study provide reliable technical bases for developing conservation strategies for O. alpina in the study area.

Ethnobotanical study of plant resources in Dhurkot rural municipality, Gulmi district Nepal

Rachana Bhandari, Bijay Pandeya, Balkrishna Ghimire — Mon, 20 Feb 2023 00:00:00 -0800

Background. Despite easy access to modern medicines, people are still using plant-based medicine for their primary healthcare needs. People, particularly in the rural area are more dependent on herbal medicines. This study aims to explore the essential plants used in medicine locally and their uses on different ailments and diseases in Dhurkot Rural Municipality of Gulmi district, a western district of Nepal.

Methodology. The study includes several visits to different community forests, interviews, and discussions with people at different time intervals from February to October 2021. Data were collected through Focus group discussion, transect walk, direct observation, and key informant interviews. Local indigenous healers, popularly known as "dhami", "pujari", "guru" and elderly people who know the uses of medicinal and aromatic plants helped us in collecting information about the utilization of plants as medicines.

Results. Altogether 67 plant species belonging to 39 families and 64 genera were used by the people for their primary healthcare needs to treat different health problems. We found that the leaves are the most used parts of the plant followed by barks. During preference ranking among 484 individuals and focus group discussion people showed a preference for Cinnamomum tamala (Lauraceae) followed by Phyllanthus emblica (Phyllanthaceae), Zanthoxylam armatum (Rutaceae). Herbs are dominant among the plant forms used followed by trees, shrubs, and climbers.

Conclusion. We conclude that people in this area still depend on plant-based medicine for their primary health care needs. Many people seek traditional remedies when they suffer from various common health problems. Besides this, abundance of medicinal plants in the region are declining due to various anthropogenic factors, infrastructure development, and climate change. Thus, appropriate conservation and management approaches along with proper identification and cultivation of important medicinal and aromatic plants are urgently required in the study area.

Heera, Naveed Akhtar, Shah Khalid, Hammad Ahmad Jan, Sobia Gul, Aiman Ali — Thu, 06 Apr 2023 00:00:00 -0700

Background: The current study was conducted to document the medicinal plants used commonly for the treatment of veterinary diseases in the study area.

Methods: The snowball sampling method was used for the selection of informants and the informants were interviewed through a semi-structured questionnaire. The documented data was quantified by indices UV (use value) and RFC (Relative Frequency of Citation).

Results: During fieldwork, about 51 plant species belonging to the 35 families were collected and ethnoveterinary data was documented for these plants. The most dominant family was Apiaceae and Solanaceae (5 Species each). The most dominant life form was herb (34 Species). The most commonly used plant part was the leaf (16 Species). The most common method of drug preparation was decoction (28 Species). The highest RFC value was calculated for Trachyspermum ammi (L.) Sprague (0.245) and the highest UV value was calculated for Trachyspermum ammi (L.) Sprague (0.28). The most commonly treated group of diseases was digestive system disorders.

Conclusion: Traditional communities still use medicinal plants for the treatment of various diseases of animals. But the knowledge of ethnoveterinary is at risk because the younger generations have no interest. Furthermore, due to deforestation and urbanization, the local medicinal flora is also at risk.

Palatability status of the Flora of Koh-e-Safaid Range Upper Kurram Valley, Khyber PakhtunKhwa North West Pakistan

Wahid Hussain, Lal Badshah, Sayed Mahmood Shah, Shariat Ullah, Asghar Ali — Tue, 30 May 2023 00:00:00 -0700

Background: The current study was carried out in Upper Kurram, Khyber Pakhtunkhwa, Pakistan from 2015 to 2019. Grazing is the most common of the land uses by domestic and wild animals. Grazing is the most significant biotic stress in terrestrial ecosystem after the fire factor.

Objectives: Objectives of the study were; to find out the Palatability status of the Flora of Koh-e-Safaid Range Upper Kurram Valley, KP Pakistan; to record the flora of grazing and browsing livestock preferences in the field.

Methodology: The palatability of plant species was recorded by observing the grazing livestock in the field. Cattle were visually observed to determine their preferences. All the information’s were confirmed from local elders. Palatable species were categorized into Highly Palatable (HP), Mostly Palatable (MP), Less Palatable (LP), Rarely Palatable (RP) and Non-Palatable (NP).

Results: The current study reported five palatability classes based on their utilization by animals. Highest number of plants fell under the group of highly palatable plants 261 (39.90%) which includes Cynodon dactylon, Dicanthium annulatum, Medicago sativa and Rubus fruticosus. The number of mostly palatable plants were 148 (22.62%) such as Alopecurus agrestis, Brachiaria ramosa, Gagea reticulata, Melica persica, Polypogon viridis. The number of rarely palatable plants were 73 (11.16%) such as Allium griffithianum, Achyranthes aspera, Alteranthera pungens, and Dioscorea deltoidea, while 27 (4.12%) plants were observed less palatable such as Coronopus didymus, Carthamus oxyacantha and Ranunculus afghanicus. A total of 145 (22.17%) plants were observed as non-palatable of which Abies pindrow, Agave americana, Alajja rhomboidea, Cedrus deodara and Hertia intermedia were significant among the non-palatable species.

Conclusions: Various factors impact the palatability of plants in different localities of the world. These factors include morphology, phenology, minerals and secondary metabolites in a plant. Like most herbivores, it preferred smaller leaves with a smaller specific leaf area and a higher dry matter content in the leaf. Phenological changes associated with climate change are related to the seasonal availability and palatability of food plants. The presence of minerals like Ca, Mg and K, Fe, Mn, Mg and Ca in different palatable plants in Kurram indicates the reason for their palatable condition. Secondary metabolites such as glycosides, alkaloids, nitrates and others such as oxalate, lectins and tannins have an adverse effect on the taste of plants.

Background: Plants play a vital role in the maintenance and economic development of an area. The current research work focuses on the investigation of economic tree species of Tehsil, Takht Bhai, and District Mardan.

Methods: For data collection different localities of Tehsil Takht Bhai were visited during 2021-2022. The plants were dried and identified with the help of Flora of Pakistan. Representative plant parts were mounted on herbarium sheets and submitted to herbarium of Center of Plant Biodiversity, University of Peshawar. The data for fuel wood was collected through standard procedures of ex-situ (artifact) and in-situ (inventory) methods. Wood depots, sawmills and farmers were visited, and information was collected from fruit markets, furniture industry, timber markets, and construction material owners through a questionnaire on the spot by interview method. The calorific value of fuel wood species was determined by Bomb Calorimeter.

Results: The plants were evaluated for their conservation status in which 7 spp. were exotic, 5 spp. were indigenous, 9 spp. were not evaluated, 2 spp. were of least concern and Acacia nilotica (L.) Willd. ex Delile was critically endangered. A total of 360000 mounds of fuel wood was sold out in summer season resulted into a revenue of PKR 241.2 million (m). The highest sale of 90000 mounds was recorded in case of Populus euramericana (Dode) Guinier, which generated 63 m of revenue. In winter season 438000 mounds of fuel wood was sold out that generated revenue of PKR 340.2 m. The highest sale of 105000 mounds was recorded in case of P. euramericana, which generated PKR 94.50 m of revenue. Maximum per annum revenue of PKR 157.50 m was generated from selling of P. euramericana. On priority basis, 50 % of the local people used Acacia modesta Wall. as fuel wood and 55 % of people used Dalbergia sissoo Roxb. ex DC. for furniture. The maximum income generated from fuel wood on basis of consumption priority was PKR 35.1 m and for furniture was PKR 33.66 m for these species respectively. It was also noted that P. euramericana was used for formation of pallets, which generates revenue of PKR 720 m per annum from 10 sites. Other economic uses include fodder (8 spp.), fruits (2 spp.), furniture (10 spp.), timber (10 spp.), constructional material (11 spp.), bed legs (7 spp.), chip boards (3 spp.), match industry (2 spp.), sport items (2 spp.), toothpicks (2 spp.), ice-cream sticks and pallets (1 sp.) each. The calorific value showed that A. modesta had highest value i.e., 5500 kcal/kg while Ailanthus altissima (Mill.) Swingle had lowest value i.e., 4400 kcal/kg. P. euramericana and Eucalyptus camaldulensis Dehn. were adopted by the locals as farm and agro forestry species.

Conclusion: From the current research, it was concluded that the inhabitants of the area rely heavily on plants for fuel wood as well as other economic purposes and also gain high revenue generation so sustainable use of plants should be made in order to support the socio-economic status of the local inhabitants.

Key words: Assessment, diversity, economic plants, fuel wood, Mardan, Pakistan, Takht Bhai.

Abdulwakeel Ayokun-nun Ajao, Yusuf Ola Mukaila, David Yahn Kenkpen — Fri, 12 May 2023 00:00:00 -0700

Background: The severity and relatively high incidence of diabetes mellitus (DM) in Nigeria call for research into discovering more potent antidiabetic agents. People of Ede have a long history of relying on medicinal plants to treat and manage various ailments, including DM. Therefore, it provides an alternative means of managing and treating the condition. This study was carried out to identify and document medicinal plants used in treating DM among the inhabitants of Ede, southwestern Nigeria.

Methods: A preliminary survey of the study area was conducted between August 2022 and February 2023. One hundred thirty-five people were selected for semi-structured interviews and questionnaires to collect ethnobotanical data, including the local names of the plants, the plant parts used, and methods of preparation. A literature survey was also conducted to determine which recorded plants have been validated scientifically for their traditional use in treating DM.

Results: Thirty-nine plants from 24 families were identified from the survey. Crinum jagus from the family Amaryllidaceae has the highest citation and fidelity level frequency. Trees (46%) and shrubs(23%) were the most abundant life forms of the recorded plants. Similarly, leaf (43%) and stem bark (19%) were the most used plant part, while decoction (54%) was the favoured method of preparation. Over 87% of the plants have been assessed for antidiabetic activities, thus lending credence to the usage of the implicated plants for DM.

Conclusion: This study indicates that the area has a rich diversity of medicinal plants for treating and managing DM. Therefore, phytochemical, pharmacological, and toxicological screening of plants that have not been tested is recommended to aid the ongoing search for effective and safe antidiabetic agents.

Use value of indigenous range grass species in pastoral northern Kenya

Erick Ouma Omollo, Oliver Vivian Wasonga, Evans L. Chimoita — Wed, 25 Jan 2023 00:00:00 -0800

Background: Land degradation is a major challenge facing the world today, with devastating effects particularly among communities inhabiting semi-arid rangelands who are more directly dependent on natural resources. Over the years, indigenous grasses have provided multiple economic, ecosystem and cultural benefits for many communities in Kenya. However, they have increasingly experienced declining abundance, diversity and productivity over the years, compromising their benefits. This study was conducted to assess use value and local knowledge of indigenous grasses among pastoral communities in Isiolo and Samburu Counties in northern Kenya.

Methods: Ethnobotanical data were computed and ranked based on four use indices: relative frequency of citation, relative importance index, cultural value index and cultural importance index. Four key use-categories of the grasses were identified including livestock forage, erosion control, thatching and making hay for sale.

Results: Top ranked grasses across these use-categories included Pennisetum mezianum, Chrysopogon plumulosus, Heteropogon contortus and Sporobolus helvolus. These are perennial grasses with multiple uses and are available in wet and dry sessions and in drought periods. While trend analysis revealed overall declining availability of indigenous grasses over recent decades, it strongly came out that the four above-mentioned most preferred species had highest declining availability as perceived by local communities.

Conclusions: These findings indicate need for enhanced actions for conserving indigenous grasses considering their multiple benefits and declining availability. Practical local knowledge, traditional structures and their pasture management models are great opportunities for creating responsive actions for rehabilitating degraded critical grazing areas while conserving key indigenous grasses.

Anatomical and phytochemical studies and ethnomedicinal uses of Colchicum autumnale L.

Mon, 16 Jan 2023 00:00:00 -0800

Background: In the world, great importance is attached to the intensification of plants. To date, most medicinal plants are only partially used. In case of Colchicum autumnale L. currently mainly the corms are used for the extraction of alkaloids. The purpose of this study was to investigate the intensification of the use of this perspective plant reported from the study area. This article examines the anatomy and phytochemistry of leaf and corm of C. autumnale, which is grown as a medicinal crop in Uzbekistan.

Methods: The leaves were fixed in 70% ethanol according to the generally accepted method; transverse and paradermal sections were examined on the fixed material. When studying the anatomical features of the leaf, preparations was formed by manually cutting a transverse section of the leaf were observed by a MOTIC V1 microscope. The slides were stained with glycerin jelly having safranin. Cells and tissues were measured using a micrometer MOB-15. To determine the amount of alkaloids contained in the leaves and in corms, a chemical analysis was carried out in the laboratory of alkaloids of the Institute of Chemistry of Plant Substances.

Results: On the transverse section of the stomata of the leaves of Colchicum autumnale anomocytic type, 2-3 rows of parenchyma and palisade cells, the characteristic size of the stomata. The root structure of C. autumnale consists of 4-5 rows of corolla, 4 protoxylems and 1 metaxylem, and the presence of rhomboid calcium oxalate crystals in its parenchyma is a characteristic feature of the species. As a result of studying the chemical composition of the plant in the conditions of the Tashkent region, it was observed that the amount of alkaloids in the aerial part of the colchicum, in the leaves was 0.4% and in the corm 0.14%.

Conclusion: The current work sought to resolve taxonomic issues involving species that share the majority of their physical characteristics and to clarify relationships between important taxa by utilizing leaf epidermal characteristics. As a result of chemical analysis, it was revealed that the amount of alkaloids in the leaves of Colchicum autumnale, introduced in the conditions of the Tashkent region (Uzbekistan), is higher than in natural regions. This proves that in the conditions of Uzbekistan it is possible to grow Colchicum and obtain high-quality raw materials.

D.T. Khamraeva, D.N. Tukhtaeva, O.K. Khojimatov, Rainer W Bussmann — Thu, 16 Feb 2023 00:00:00 -0800

Background: This study determined the results of the introduction of the Ferula tadshikorum, and comparatively studied the content of proteins and polysaccharides in leaves and roots in three age individuals.

Methods: The work used phenological, protein and polysaccharide chemical analyses, as well as a survey on the use of Ferula tadshikorum among local residents of Surkhandarya region of Uzbekistan.

Results: Under the conditions of introduction, phenological observations of the growth and development of Ferula tadshikorum were carried out. Based on 4-year experiments, we concluded that, in contrast to the natural conditions, in Tashkent Botanical Garden a shortening of the duration of stages in juvenile and immature individuals, as well as an increase in the number of virginal individuals, is observed in ontogenesis. For the first time, the chemical composition of roots and leaves was studied in three individuals of different ages: 4-year-old introducents of the virginal stage of development, and natural individuals of medium, mature virginal age. The analysis for the content of protein and protein N found that the average protein content in the roots of the Ferula tadshikorum plant ranged from 2.3% to 7.12%, while in the leaves it ranged from 10.23% to 25.56%. The roots and leaves of mature virginal individuals of Ferula tadshikorum had the greatest nutritional value in terms of total protein content. For the first time, the content of various groups of polysaccharides in the roots and leaves of 3 virginal samples of Ferula tadshikorum was elucidated, and alcohol-soluble sugars, water-soluble polysaccharides, pectin substances and hemicellulose were isolated. According to the monosaccharide composition, the roots contained especially to glucogalactaarabans, the leaves arabinogalactans. Some recipes of folk medicine on the use of leaves and resin for the treatment of certain human diseases are given.

Conclusion: For the medicinal plant Ferula tadshikorum, new prospects are opening up for the use in both folk medicine and official medicine. In the future, more in-depth phytochemical studies are needed to identify the therapeutic potential of the Ferula tadshikorum.

A note on an edible fern of Nepal: Blechnum orientale L.

Rijan Ojha, Hari Prasad Devkota — Sat, 29 Apr 2023 00:00:00 -0700

Background: The consumption of ferns as vegetables and pickles in Nepal is a noteworthy phenomenon. Diplazium esculentum stands out as one of the most commonly consumed ferns. Being rich in plant resources, eastern Nepal remains relatively unexplored compared to central Nepal. Therefore, the present study seeks to provide a brief account of the edible uses of Blechnum orientale, a fern species, from eastern Nepal.

Methods: Multiple field visits were conducted in Pathari Municipality and Kanepokhari Rural Municipality of Morang district. The habitats where B. orientale was collected by local vendors were examined, ethnobotanical uses, photographs, and market prices were recorded.

Results: From April to May, young fronds of B. orientale were collected from local community forests by Tamang, Limbu, and Magar tribes of an area. Young fronds were washed, boiled to soften them, and used to prepare vegetables. Pickles are also made by mixing boiled young fronds with potatoes, green chili, onions, salt, mustard oil, and flax seed powder. Local vendors sell the fronds in bundles along Mahendra Highway in the price of 50 to 100 Nrs per bundle.

Conclusion: The fern is a vital vegetable source for local communities during the monsoon season, providing sustenance and income generation opportunities. Sustainable collection and commercialization are recommended.
