ABSTRACT
The investigation aims to better understand the resource status of Rhodiola kirilowii, analysis the suitable habitat of wild Rh. kirilowii and protect the wild resources of Rh. Kirilowii, promoting the sustainable utilization of Rh. kirilowii resources. In this paper, we investigated the wild resources of Rh. kirilowii in 16 counties of Sichuan, Qinghai, Gansu and Yunnan by means of investigation and sampling investigation combined with interview. The results showed that the population densities of wild Rh. kirilowii in 4 provinces were very different and the reserve of wild resources decreased gradually in many areas. According to the survey results, the current total reserve of Rh. kirilowii in four provinces was about 1 100 t. The reserve of wild Rh. kirilowii in Sichuan province was the largest. Simultaneously, the Rh. kirilowii had a certain ecological value. We found that a sand control base with planting Rh. kirilowii was set up in Hongyuan County of Sichuan Aba Tibetan and Qiang Autonomous Prefecture. The investigation provides a scientific basis for the development and sustainable utilization of Rh. kirilowii resources.
ABSTRACT
The study is aimed to clarify the actual original plant, find out the usage status and the resource distribution of the Tibetan medicinal plant "Bangga". By using the way of the literatures survey, interview and investigation, it found out that the actual original plant of the Tibetan medicinal plant "Bangga" were the whole dried plant or the aerial part of Aconitum tanguticum or A. naviculare of Ranunculaceae, among which A. tanguticummainly distributed in Sichuan, Gansu, Qinghai, Tibet (Qamdo), and A. naviculare mainly distributed in Tibet. Sichuan, Gansu, Qinghai and other Tibetan areas mainly used the resources of A. tanguticum, Tibet (except the Qamdo area) mainly uses the A. naviculare, which resource was imminent in danger. Other species described in the literature were not used. It showed that the use of herbs related to their resources, it is recommended to strengthen the protection and guide the market.
ABSTRACT
Through the textual research, resource investigation, literature reviews (including Flora of China, municipal Flora, pharmacopoeia of China and municipal drug standards) and identification of commercial drugs on Cuscutae Semen, it was found the species described in the herbal textual was Cuscuta chinensis, with good quality from Shandong and Henan Province. The identification of commodities showed the majority drugs were from C. australis, varied from the ancient herbal textuals .Mordern literature reviews indicate that it was necessary to strengthen the research on Cuscutae Semen from C. australis, C. chinensis and C. japonica because of their differences in resources, macroscopical and microscopical characters, while wrong descriptions in some literatures. It was suggested that the two species (C. australis and C. chinensis) should be separated in pharmacopoeia of China. The study provides scientific basis for the development and utilization of Cuscutae Semen.
ABSTRACT
Objective To investigate the circulation and use of Akebiae Caulis and Clematidis Armandii Caulis;To provide references for clinical safe medication. Methods Literature review, field survey and telephone interview were used to conduct the investigation. Results ① The market currency of the Akebiae Caulis and Clematidis Armandii Caulis was very confused, and the mainly medicinal materials on the market were Clematidis Armandii Caulis. ② The majority used medicinal materials were Clematidis Armandii Caulis, and Akebiae Caulis was rarely used. ③ The Chinese Pharmacopoeia collected Akebiae Caulis and Clematidis Armandii Caulis separately, but there was phenomenon of using Clematidis Armandii Caulis replacing of Akebiae Caulis. Conclusion Market of Akebiae Caulis is shrinking; the phenomenon of using Clematidis Armandii Caulis to replace Akebiae Caulis widespread in clinic. There are differences in the efficacy of Akebiae Caulis and Clematidis Armandii Caulis, so they should be distinguished and cannot be used to mix or substitute.
ABSTRACT
Objective To understand the distribution condition of resources of medicinal plant of Euodiae Fructus;To provide references for resource conservation and standardized plantation of Euodiae Fructus. Methods Literature search, interview survey and field survey were conducted to investigate the resource conditions of the main producing areas of Euodiae Fructus. Samples were collected and TKW of the medicinal plant was weighted. Results Currently, the main producing areas of Euodiae Fructus are provinces of Jiangxi, Guizhou, Hubei, Hunan and part of provinces and places of Guangxi, Anhui, Zhejiang, Shanxi, and Chongqing. Commercial Euodiae Fructus mainly comes from private investors. The wild resources of Euodiae Fructus are few. The TKW of the medicinal plant is within 5.34-45.62 g, with great differences. The national annual output of cultivated Euodiae Fructus is around 3500 t. The production and marketing is in balance. The price for Euodiae Fructus is relatively stable. Conclusion The plantation of Euodiae Fructus is dispersing, with small scale, low degree of standardization and intensification, and great quality differences. Standardized, large-scale, and industrialized plantation base should be established, and the assessment system for medicine quality should be perfected, with a purpose to ensure the qualified and stable production of Euodiae Fructus. Meanwhile, wild resource production should be enhanced to maintain the biological diversity and promote the sustainable development of Euodiae Fructus.
ABSTRACT
ObjectiveTo investigate the species of wild Chinese medicinal herbs for treating liver diseases in Quanzhou City of Fujian Province.Methods Based on the field investigation combined with literature reference, induction and analysis of the species of wild Chinese medicinal herbs for treating liver diseases in Quanzhou City of Fujian Province have been conducted.ResultsIt was found that there are 59 families, 112 genera, and 132 species of wild Chinese medicinal herbs for treating liver diseases in Quanzhou City of Fujian Province, most of which belong to angiosperm. 15 families, 21 genera, and 21 species are recorded in the Chinese Pharmacopoeia (2010 edition). Compositae has the largest number of genera and species (16 genera &19 species), followed by leguminosae (8 genera & 8 species) and labiatae (6 genera & 8 species). Chinese medicinal herbs for heat-clearing and promoting urination and leaching out damp amount to 69 and 20 species respectively. Over 88% of these wild medicinal herbs can be used to treat various liver diseases, and 46 species are used with high frequency. They are mainly taken by water decoction and oral administration.ConclusionWild Chinese medicinal herbs for treating liver diseases in Quanzhou City of Fujian Province are rich in species and resources, and are worth further development and utilization.
