Lancea Seed Quality Standards And Medicinal Quality Standards

Rhizoma Atractylodis Lanceae is a commonly used traditional Chinese herbal medicine. As a regular medicine, it is the dried root of Atractylodes lancea (Thunb.) DC. recorded in various editions of Pharmacopeias in China and also called " maocangzhu " or "nancangzhu" . It's widely used to cure much disease in clinic. Modern pharmacology tests have proved that maocangzhu has effects on abdominal distention, diarrhea, watery distention, rheumatism etc. Chinese doctors in successive dynasties have a high regard for Rhizoma Atractylodis Lanceae in the maoshan mountain. They think it is the genuine medicinal herbs. But the contradiction between human , environment and resources made the subsistent conditions of "maocangzhu" not exist. Rhizoma Atractylodis Lanceae in the maoshan mountain can't be carried out commercial collection. While the resources are abundant in hubei province and the quality is high. In order to supply the demand of market and protect the wide resources and the ecological environment, we built exemplary bases in yingshan city and luotian city, and carried out standard planting. We worked out research on Standard Operation Procedure ( SOP ) and quality standard. In this paper we only expound the sections of seed quality standard research and quality standard research, the contents read as follows:1.Introduction. Textual research on the Chinese medicinal herbs, Biological characters and growing habits, Germplasm resources, Chemical components, Pharmacological action, Clinic use, research on comprehensive utilization of Rhizoma Atractylodis Lanceae are summarized in this paper.2. The section of investigation of the plant resources and the environmental investigation in the exemplary bases. We investigated Rhizoma Atractylodis Lanceae in the main producing area and found the "maocangzhu" in hubei province is the same as genuine medicinal herbs in maoshan mountain of jiangsu province. Both are Atractylodes lancea (Thunb.) DC.. So we chose the bases in yingshan city and luotian city. The results of environmental investigation in the exemplary bases show that the bases are suited to the green standard and may establish the bases according to the requirement of GAP.3. The section of seed quality standard research of Rhizoma Atractylodis Lanceae. The quality of seed and seedling embodies the scientific and technological level of agriculture. It is the key factor toimpair quality and quantity. So we have worked out the seed quality standard of Rhizoma Atractylodis Lanceae in order to guarantee its fine and improved quality.4. The section of quality standard research of Rhizoma Atractylodis Lanceae.A systematical research about Rhizoma Atractylodis Lanceae was carried out, such as identification of characters, location, collection, preparing method, storage, identification of quality ( including morphology, physical-chemical character ), content assays etc. Basing on the green imports and exports trade standard, we have determined the rudimental content of heavy metal and the organ chlorine pesticides residual in the medicinal material in order to guarantee its quality to accord with the green standard of medical plant.
