Background: Fig trees are ecological keystone species in many tropical regions and play important roles in the spirituality, nutrition and health for many rural communities. Although the tropical forests in Myanmar contain many fig species, little ethnobotanical knowledge on their uses has been recorded.Information about the uses and conservation related actions of figswould be helpful in development ofstrategic policy for sustainable use and biodiversity conservation of the country. We showcase the rich ethnobotanical knowledge as well as the variety of collection and conservation practices related to figs among five ethnic groups in Southern Shan State. Methods: We performed both key informant and semi-structured interviews with 114 informants from five ethnic groups. Their uses for figs were categorized according to local practices and recipes. Informants were asked about trends in conservation status over the past 10 years and any conservation related customs and practices. Data were analyzed quantitatively by use report (UR) and use value (UV). Results: Informants reported the uses of eight fig species (Ficusauricularta，F.concinna, F. geniculata，F. hispida, F. racemosa, F. religiosa，F. semicordata, and F. virens).F. geniculata and F. virens were most useful (UR = 228) and were used by all five ethnic groups, corresponding to a high use value (UV = 2). Treatments for 16 diseases were reported from seven species. Household consumption, economic, and sacred uses were accompanied by sustainable practices of harvest and protection. Traditional taboos, in situ and ex situ conservation were practiced especially for highly demanded species (F. geniculata and F. virens), and the sacred fig F. religiosa.Conclusion: Findings suggest that figs are useful for nutrition (all informants) and medicine (13.16% of the informants) in the study area. Traditional taboos, in situ and ex situ conservation practices help to maintain sustainable utilization of locally important figs. This is an early contribution to the traditional knowledge of edible figs. Although similar uses have been reported in neighboring countries for seven of the fig species, the ethnobotanical use of F. concinna is novel.

Background Most regions of Myanmar fall within the Indo-Burma Biodiversity Hotspot and are threatened with biodiversity loss. Development of a comprehensive framework for sustainable development is crucial. Figs are ecological keystone species within these regions and are also important for traditional spiritual food and health uses, which often have accompanying conservation practices. The traditional use and management of figs may offer clues to help guide the development of national policies for sustainable development. In this study, we showcase the rich ethnobotanical knowledge as well as the variety of collection and conservation practices of figs among five ethnic groups in Southern Shan State. Methods We performed both key informant and semi-structured interviews with 114 informants from five ethnic groups. Their uses for figs were categorized according to local practices and recipes. Informants were asked about trends in conservation status over the past 10 years and any conservation-related customs and practices. Data were analyzed quantitatively with common quantitative ethnobotany indices, the use report (UR) and use value (UV). Results Informants reported the uses of eight fig species (Ficus auricularta, F. concinna, F. geniculata, F. hispida, F. racemosa, F. religiosa, F. semicordata, and F. virens). F. geniculata and F. virens were most useful (UR = 228) and were used by all five ethnic groups, corresponding to a high use value (UV = 2). Treatments for 16 diseases were reported from seven species. Household consumption, economic and sacred uses were accompanied by sustainable practices of harvest and protection. Traditional taboos, in situ and ex situ conservation were common especially for highly demanded species (F. geniculata and F. virens) and the sacred fig F. religiosa. Conclusion Findings suggest that figs are useful for food (all informants) and medicine (13.16% of the informants) in the study area. Traditional taboos, in situ and ex situ conservation practices help to maintain sustainable utilization of locally important figs. This is an early contribution to the traditional knowledge of edible figs. Although similar uses have been reported in neighboring countries for seven of the fig species, the ethnobotanical use of F. concinna is novel.

Ethnopharmacological relevance A new field of enthnopharmacology has opened, where pharmacological studies draw their attention from the conventional only-medicine approach towards the dietary dimension. The uses of Ficus species in the human diet have been extensively documented by ethnobotanical field surveyors. Overlap commonly exist between the dietary and medicinal selection of Ficus species but not for choices of the plant parts and development stages, which leave a large space for ethnopharmacological study. Aims of the study 1) To review published works on the dietary uses of Ficus species and their food-medicine overlap based on traditional uses, and 2) to spark interest in ethnopharmacological studies on the dietary uses of Ficus species. Materials and methods Data was collected and analyzed from many sources, including published and unpublished ethnobotanical field surveys, taxonomic and distribution information, international journals, books, thesis, floras, reports and professional databases. The possible biases arising from data sources are assessed to make sure that the dataset are global representative. Results A total of 132 Ficus species are reported for dietary uses, including one subspecies and four varieties. Those species are found across all of the six subgenera of the genus Ficus. For distribution, 98 species from the Indo-Australasian region, 27 species from the African tropics (with one species, F. palmata, from both the two regions) and 8 from the Neotropics. The parts most commonly used are the figs (i.e. syconium or fruits) (110 species) and leaves (67 species), in various growth stages. It is also found that the certain plant parts of 78 species are used both for dietary and medicinal purpose. Among which the figs are frequently cited in the treatment of diarrhea and oligogalactia, the leaves in the treatment of diarrhea, stomach complaintsas, antidote and diabetes, the latex in the treatment of intestinal worms and wounds, and the barks in the treatment of diarrhea. Conclusions We demonstrate that throughout its area of distribution, the genus Ficus is generally used as a dietary plant, although use of a individual species seems uncommon. Furthermore, we highlight the diet-medicine overlap of the uses of this genus, which should enable further understanding of the potential for broader health benefits, rather than limiting studies in this genus to its only-medicinal properties

Ethnopharmacological relevance: Magian (Zanthoxylum myriacanthum var. pubescens Huang) is widely consumed as an indigenous remedy for digestive disorders, detoxification, detumescence and analgesia by the ethnic groups in Xishuangbanna, SW China. A related species, Huajiao (Zanthoxylum schinifolium Sieb. et Zucc.), has similar uses in traditional Chinese medicine. We aimed to scientifically validate the traditional uses by investigating and comparing the chemical composition, antimicrobial and anti-inflammatory activities of the essential oils of Magian and Huajiao. Materials and methods: Essential oils were collected from the fruits of Magian and Huajiao by simultaneous distillation extraction and identified by gas chromatography-mass spectrometry (GC-MS) analysis. To assess antimicrobial activity, the minimum inhibitory and bactericidal concentrations (MIC and MBC) against 7 microbial strains, including 5 food-borne pathogens, were evaluated by serial dilution with a standardized microdilution broth methodology. For anti-inflammatory activity, the cell viability and nitric oxide (NO) production were determined on lipopolysaccharide (LPS)-stimulated RAW 264.7 cells by MTS assay and the Griess reagent system, respectively. Results: The essential oil from Magian is rich in limonene (67.06%) and has strong antimicrobial activity against the tested pathogens and spoilage organisms, with MIC ranging from 64 to1024 mu g/ml and MBC ranging from 64 to 2048 mu g/ml. It also showed anti-inflammatory activity by significantly inhibiting nitric oxide (NO) production induced by LPS in RAW 264.7 cells at 0.04 parts per thousand without effects on cell viability. Furthermore, it showed relatively stronger antimicrobial and anti-inflammatory activities than the essential oil from Huajiao. Conclusions: Our findings not only justify the use of Magian as an indigenous remedy for digestive disorders, detoxification, detumescence and analgesia, but also suggest that it could be promoted as a preferred substitute for Huajiao.

Background Conservation of biodiversity is primary important of today’s critically vulnerable environment. Efficient conservation can be possible only with the long-term participation and understanding of the communities. Ritual beliefs of the indigenous people are one of the important tools to understand the local communities and aid the nature conservation. In this paper, we documented contemporary ritual practices and ritual plant uses among the Naxi people and discussed the importance of traditional knowledge on ritual practice in the conservation of plants in the mountains presenting a case study of the Dongba culture. Methods This study was carried out from July in 2013 to July in 2014. To document and analyze the present state of the ritual plant used by the Naxi people we conducted an ethnobotanical survey. We interviewed local people including Dongba priests using the semi-structured questionnaire. During the field study, we participated in the local religious activities to witness the use of different plants in ritual activities of the Naxi people. We interviewed twenty-two key informants and eleven of them were male. All the specimens of documented species were collected and deposited at the herbarium of Kunming Institute of Botany. Results The survey results revealed the Naxi people possessed sound knowledge of the traditional ritual plants and great diversity of plants used in many of Naxi rituals and festivals. From the survey, we documented 32 ritual plant species belonging to 24 genera of 17 families used in various ritual activities. The ritual plants were grouped into two categories, namely those burned as incense, and those used for decoration. The incense plants like Olea europaea subsp. cuspidata and Pistacia weinmanniifolia were probably promising natural aromatic resource. Plants of genus Quercus were the most frequently used species. The places for ritual activities were diverse, such as the incense burners inside and outside the house and sacred trees at the Baishuitai. Local people except the young generation had an abundant of traditional knowledge. Conclusions Our study shows the live ritual activities and the beliefs of the residents are keeping the plant diversity and the entire forest preserved as sacred mountains. Our study emphasizes traditional belief and an alternative view of conservation that is not led mainly by governmental policies, as local practices and ritual plants uses play as constant reminders to the Naxi on nature conservation. However, further research is recommended for in-depth understanding the role of traditional belief in biodiversity conservation.

The young leaves of seven Ficus species including F. virens var. sublanceolata, F. auriculata, F. vasculosa, F. callosa, F. virens var. verins, F. racemosa and F. oligodon are traditionally consumed by local people in Xishuangbanna. The dry young leaves were studied for their total phenolic and flavonoid contents. The 90% ethanolic extracts of the young leaves were screened for potential antioxidant capacity by employing different in vitro assays including ABTS + and DPPH radical scavenging capacities, ferric reducing power and lipid peroxidation inhibition properties. Extracts from F. virens var. sublanceolata and F. auriculata showed higher antioxidant activity in all the systems than other species. We concluded that these two species are promising sources of natural dietary antioxidants. According to our statistical analysis, the total phenolic and flavonoid contents appear to be responsible, at least in part, for the extracts’ excellent antioxidant capacity and all the extracts exhibited dose-dependent antioxidant activity.

Sacha Inchi oil was studied for its physicochemical characteristics, chemical composition, radical scavenging activity and storage stability. The fatty acid composition was studied by gas chromatography–flame ionization (GC–FID) and the analysis showed that the oil is highly enriched in α–linolenic (43.5%) and linoleic (39.6%) acids. The tocopherol content in the oil analyzed by high performance liquid chromatography/ultraviolet– visible detector (HPLC/UV–VIS) was also high (161.87 mg.100 g -1 ). Both DPPH and ABTS assays detected relatively high radical scavenging activity. After twelve months of storage, the oil showed relatively good storage stability. The results will help guide further investigation of the health benefits of Sacha Inchi oil for the population and the development of better edible oil products and nutraceuticals.

Background The genus Ficus, collectively known as figs, is a key component of tropical forests and is well known for its ethnobotanical importance. In recent decades an increasing number of studies have shown the indigenous knowledge about wild edible Ficus species and their culinary or medicinal value. However, rather little is known about the role of these species in rural livelihoods, because of both species and cultural diversity. Methods In this study we 1) collected the species and ethnic names of wild edible Ficus exploited by four cultural groups in Xishuangbanna, Southwest China, and 2) recorded the collection activities and modes of consumption through semi-structured interviews, 3) investigated the resource management by a statistical survey of their field distribution and cultivation, and 4) compared and estimated the usage intensities by the grading method. Results The young leaves, leaf buds and young or ripe syconia of 13 Ficus species or varieties are traditionally consumed. All the species had fixed and usually food-related ethnic names. All four cultural groups are experienced in the collection and use of edible Ficus species as vegetables, fruits or beverages, with the surplus sold for cash income. Different cultural groups use the Ficus species at different intensities because of differences in availability, forest dependency and cultural factors. Both the mountain and basin villagers make an effort to realize sustainable collection and meet their own and market needs by resource management in situ or cultivation. Conclusions In comparison with reports from other parts of the world, ethnic groups in Xishuangbanna exploited more edible Ficus species for young leaves or leaf buds. Most of the edible species undergo a gradient of management intensities following a gradient of manipulation from simple field gathering to ex situ cultivation. This study contributes to our understanding of the origins and diffusion of the knowledge of perception, application and managing a group of particular plant species, and how the local culture, economic and geographical factors influence the process.
