“…We considered IASc > 0.25 as a cutoff value for identifying the highly consented species. Medicinal plants and their elevation range (B. ciliata: 900-1700 m, C. asiatica: 500-2100 m, P. polyphylla: 1500-3500 m, S. chirayita: 1500-2500 m and V. jatamansi: 1400-3600 m) and distribution throughout Nepal from east to west [57][58][59] hinted that these species are more accessible than others leading to frequent collection in mid-hills. Accessible plant species are often considered more useful than less abundant or less accessible [11,17].…”

An account of total of 58 plant species including 57 genera and 43 families was reported as useful in ethnomedicine from semi-structured questionnaire survey to the 76 participants of Kaski and Baitadi districts, Nepal. Fieldwork and participatory meetings were carried out between September 2017 and January 2018. A total of 419 emic use reports including 150 from Kaski and 269 from Baitadi were reported from 58 ethnomedicinal plant species. Each species was reported for 2–43 use reports and each participant recorded 1–12 use reports. About 25% (n = 104) use reports were associated with the treatment of digestive system disorders followed by 83 for general complaints. Of the species assessed, 53 species had IASc value < 0.25 and only five species had > 0.25. Species Swertia chirayita, Paris polyphylla, Bergenia ciliata, Valeriana jatamansi and Centella asiatica with > 0.25 IASc were found to be highly consented; however they were incongruent between the sample groups and sites. Divergent plant use knowledge specific to each sample district and group was corresponding to the heterogeneity of socio-economy and culture of the sites. Gender, ethnicity, household economy and food availability of the respondents were leading factors affecting the plant use knowledge. Despite the sites were relatively homogenous in eco-physiography, they possessed the distinct plant use knowledge, hinted that the socio-economic factors are more explanatory in plant use knowledge.

“…It has met the health care need of three-quarters of the population of the world, which is of great importance to save human life and promote economic development, especially for those who live in rural areas (He et al, 2018). As a matter of fact, concomitant with the rise of commercial demand and overharvesting, high-value medicinal plants will face an increased risk of complete extinction due of course to the fact that wild collection is the main source for the supplement of medicinal plants (Chi et al, 2017;Cunningham et al, 2018;Applequist et al, 2020;Kunwar et al, 2020). For example, Gentiana rigescens Franch has become one of the 10 most important endangered medicinal plants in Yunnan province since 2002.…”

A Novel Multi-Preprocessing Integration Method for the Qualitative and Quantitative Assessment of Wild Medicinal Plants: Gentiana rigescens as an Example

et al. 2021

Until now, the over-exploitation of wild resources has increased growing concern over the quality of wild medicinal plants. This led to the necessity of developing a rapid method for the evaluation of wild medicinal plants. In this study, the content of total secoiridoids (gentiopicroside, swertiamarin, and sweroside) of Gentiana rigescens from 37 different regions in southwest China were analyzed by high performance liquid chromatography (HPLC). Furthermore, Fourier transform infrared (FT-IR) was adopted to trace the geographical origin (331 individuals) and predict the content of total secoiridoids (273 individuals). In the traditional FT-IR analysis, only one scatter correction technique could be selected from a series of preprocessing candidates to decrease the impact of the light correcting effect. Nevertheless, different scatter correction techniques may carry complementary information so that using the single scatter correction technique is sub-optimal. Hence, the emerging ensemble approach to preprocessing fusion, sequential preprocessing through orthogonalization (SPORT), was carried out to fuse the complementary information linked to different preprocessing methods. The results suggested that, compared with the best results obtained on the scatter correction modeling, SPORT increased the accuracy of the test set by 12.8% in qualitative analysis and decreased the RMSEP by 66.7% in quantitative analysis.

“…Then, based on these assessment results, proper measures can be taken for sustainable management (Cunningham 1996). Furthermore, strategies and policies for restoration of overexploited species depend on identifying potential suitable habitats where they can be grown in the future (Casazza et al 2016, Kunwar et al 2020). As such information for T. govanianum is needed for its conservation, this study aimed to 1) assess current population, production and use, 2) evaluate potential habitats and 3) analyze trade and vulnerability issues for conservation.…”

“…As such information for T. govanianum is needed for its conservation, this study aimed to 1) assess current population, production and use, 2) evaluate potential habitats and 3) analyze trade and vulnerability issues for conservation. There are a few studies in Nepal assessing the interactions of population, production, distribution and use of medicinal plants (Subedi et al 2015, Kanel et al 2017, Kunwar 2018, Kunwar et al 2020, Charmakar et al 2021). However, previous studies assessing the interactions of population, production, distribution and use of T. govanianum are almost negligible.…”

Trillium govanianum is known to be used for primary health care and household economy, however detailed information on its ecology and importance for local economy has remained unknown. In this study, we investigated T. govanianum population, production and distribution range, as well as its use, trade and vulnerability in Nepal. We show that the current practice of T. govanianum rhizome marketing has resulted in unsustainable harvesting, putting in extreme pressure on its habitats and populations. Harvesting methods such as premature harvesting and mass collections, without knowing actual population size and distribution, may have serious negative effects on reproduction, growth and survival of the species. To gather data and information, we sampled 80 quadrats and 320 (1 × 1 m) nested plots along with 96 interviews. Information on species occurrence points was gathered from various sources including direct field sampling and predicted potential suitable habitat using a maximum entropy model (MaxEnt). Rapid vulnerability assessment (RVA) was used to assess the conservation status of the species. Our results showed that T. govanianum occurs in 26 districts of Nepal and can be expected in 10 more mountainous districts along the elevation range between 2400 m and 4050 m. Among the environmental factors, elevation, precipitation and temperature were found to be the most influential for the species' distribution. Market‐led unsustainable collections were prevalent and T. govanianum collections were traded as an adulterant to Paris polyphylla, a highly traded medicinal plant. We found that T. govanianum is a vulnerable species with threat category I. Therefore, conservation efforts are urgently needed, including protection of its key sites and habitats along with sustainable use so as to save its existence.
