Discussion on Commodity Specification and Grade Standard of Radix and Rhizoma of Chinese Materia Medica / 中国中医药信息杂志

Through literature review and field investigation, the commodity specification, grade standard and application situation of radix and rhizoma of Chinese materia medica were analyzed, and research methods and achievements of radix and rhizoma of Chinese materia medica were concluded, the existing problems of radix and rhizoma of Chinese materia medica were analyzed and concluded, and proposed identification methods fully referring Chinese methods of radix and rhizoma of Chinese materia medica. By combining modern planting and initial processing methods, classification indicators were specifically quantified, grade standard radix and rhizoma of Chinese materia medica conforming to current pharmacopoeia and meeting practical operation was designed, which were in accordance with market demand for high quality and high price standard system.

Study on status of criteria for formulating specification and grade of Chinese medicinal materials based on filed survey in medicine market / 中国中药杂志

The commodity specification and grade is an important factor affecting the price of Chinese medicinal materials. Specification and grade standard play an important role in transferring quality information in Chinese medicinal market, which is characterized by highly information asymmetry. This paper analyses and expounds six classification methods of commodity specification and grade of Chinese medicinal materials based on the market investigation carried out in the medicine markets in Anguo, Bozhou, Yulin, Chengdu and so on.

Research model on commodity specification standard of radix Chinese materia medica / 中国中药杂志

As an important part of the market commodity circulation, the standard grade of Chinese traditional medicine commodity is very important to restrict the market order and guarantee the quality of the medicinal material. The State Council issuing the "protection and development of Chinese herbal medicine (2015-2020)" also make clear that the important task of improving the circulation of Chinese herbal medicine industry norms and the commodity specification standard of common traditional Chinese medicinal materials. However, as a large class of Chinese herbal medicines, the standard grade of the radix is more confused in the market circulation, and lack of a more reasonable study model in the development of the standard. Thus, this paper summarizes the research background, present situation and problems, and several key points of the commodity specification and grade standard in radix herbs. Then, the research model is introduced as an example of Pseudostellariae Radix, so as to provide technical support and reference for formulating commodity specifications and grades standard in other radix traditional Chinese medicinal materials.
