ABSTRACT
The plants of Bletilla are one of the groups in Orchidaceae with the highest economic value. As the traditional Chinese medicinal material, Bletillae Rhizoma exhibits excellent efficacy in hemostatic, antibiosis, detumescent, anticancer activities and regenerating tissue to heal wound, which has great development potential. However, Bletillae Rhizoma is mainly collected from wild resources. At present, the quantity of wild resources of Bletilla plants has sharply decreased and is far from meeting the needs. Resource appraisal and breeding and cultivation of excellent germplasms of Bletilla plants are important for scientific utilization of the resources of the genus. This paper reviewed the following researches of Chinese Bletilla resources: species and distribution, genetic diversity, active ingredient evaluation, breeding, as well as seeding production and cultivation techniques. Suggestions were also provided in further researches on the resources evaluation, sustainable development and efficient utilization of Chinese Bletilla plants.

At the end of 2017, the former China Food and Drug Administration promulgated " the Guiding Principles for the Assessment of Chinese Medicine Resources" whose purpose is establishing the concept of " the production of Chinese traditional medicines, herbal pieces and etc. should be based on the premise of ensuring the production and quality of Chinese medicine resources" for a licensed holder of a drug listing or a production enterprise of Chinese Medicine by assessing this work through the resources of Chinese Medicine which finally achieves the strategic significance of promoting the sustainable utilization of Chinese medicine resources. Under the guidance of the overall idea of "the total amount is not reduced and the supply is guaranteed", this paper focuses on the following two methods of assessment: ①"family property assessment" of Chinese medicine resources based on "fixed total amount". ② "Supply and demand balance assessment" of Chinese medicine resources based on "supply guarantee". In this paper, we discuss the difference and relationship between the national survey of Chinese medicine resources and the assessment of Chinese medicine resources. Finally, we put forward a basic strategy called" supply and demand balance assessment" of Chinese medicine resources based on "supply guarantee" that will guide the Industrial production of traditional Chinese medicine.
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
In order to figure out the status and distribution of the wild and cultivated resources of traditional Chinese medicine Daphnes Cortex, its suitable habitat and endangering factors were analyzed to provide the basis for its rational use, protection and cultivation.Our research group tooka resources survey in Shanxi, Gansu, Sichuan and Qinghai provinces, which include 23 counties. Investigation and sampling investigation combined with interview were carried out. The total reserve of resources was estimated through route-quadrat method in combination with the vegetation and soil-type map area method. The results indicated that there was no obvious change between the present distribution ranges of the wild Daphnes Cortex and its historical records, but the density of the population has undergone major changes. The wild reserves resources has declined seriously, even on the verge of exhaustion in some regions. According to the survey results, the current total reserve of the wild Daphnes Cortex in the four provinces was no more than 600 tons. Simultaneously, we only found the cultivated resource in a mountain at an altitude of about 2 800 m in Kang county of Gansu province, which cropping scope was about 33 000 m². The cultivated resource can't provide medicinal products at present, because their growing period is too short to have curative effect. Destructive excavation and the longer growth cycle result in a sharp decline of the wild resources reserves, even to the point of extinction. Artificial cultivation of product will become the main source of medicinal resources in the future. Therefore, we must protect its suitable habitat, formulate rational harvesting policy, strengthen the supervision of government departments, collect and establish the germplasm nursery and seed bank. On the basis, we must carry out studies into seed-selecting and breeding as well as rapid propagation and growth technology at once.
ABSTRACT
Shennongjia is well known as the national treasure of traditional Chinese medicine resources at home and abroad. In order to provide Shennongjia with better protection of traditional Chinese medicine and promote the sustainable utilization of its resources, based on the specific analysis of She nnongj ia′s conservation status and available resources, we put forward primary strategies and specific measures for the sustainable utilization framework of Shennongjia traditional Chinese medicine resources, in view of resources conservation, development, utilization, as well as the resources administration.
