三七药材质量特征和商品规格等级标准研究

通过市场调查和文献研究,了解三七药材质量特征和商品状况。并从市场和产地采集样品进行分析,结合生产实际,修订三七药材商品规格等级标准。该研究将三七药材按照不同部位和采收时间划分为主根(又分为春七和冬七)、筋条和剪口共4种规格,春七和冬七又按个头大小简化为20头、30头、40头、60头、80头、120头、无数头和等外8个等级。在此基础上分析比较了三七不同规格、等级间药材的密度和内在成分含量的差异,并探讨了产地、种植年限、采挖时间对三七商品规格等级影响,修订完善了三七药材商品规格等级标准。同时,建议《中国药典》在中药材三七项下按照药用部位和规格进一步细分药材的质控指标,并明确各中药材"采收年限"和药材密度,合理引导中药材生产,保证药材质量。

Qualitative characteristics and classification study on commodity specification and grade standard of Panax notoginseng

Through the markets investigations and literature surveying, this paper investigates and analyzes the qualitative characteristics and commodity condition of Panax notoginseng. And the samples collected from market and origin were analyzed in order to revise the commodity specification and grade standard of P. notoginseng combined with production practice. In this paper, the authors divide the P. notoginseng into 4 commodity specification which are root (including Cunqi and Dongqi), Rhizome and rootlet according to different parts and harvest time. And the root were divided into 8 grade which are 20, 30, 40, 60, 80, 120, countless and substandard. The density and internal components between the different commodity specification and grade of P. notoginseng were also compared. As well as the effect of different producing area, cultivation years and harvesting time on the commodity specification and grade of P. notoginseng were researched. On this basis, we revise and improve the commodity specification and grade standard of P. notoginseng. Moreover, we suggest the quality control indexes of P. notoginseng should be developed according to the different medicinal part and commodity specification in CHP. In order to guide the standardized production of traditional Chinese medicine and ensure the quality of medicinal materials, the cultivation years and density of each medicinal materials should also be indicated in CHP.
