Research progress in correlation between commodity specification level and quality of Polygala tenuifolia / 中草药

The quality of Chinese herbal medicine is an important prerequisite for ensuring clinical efficacy and safety. The current commodity specification of medicinal herbs is the summary of the traditional Chinese medicine practitioners' experience of "assessing the quality by distinguishing the features of traditional Chinese medicinal materials". However, with the continuous introduction and acclimatization and large-scale cultivation of wild medicinal herbs, the traits of some medicinal herbs have changed greatly compared with the previous one, resulting in that the market circulation specifications of these medicinal herbs is inconsistent with the current commodity specification. In this paper, by consulting the modern monographs, literatures and so on, we analyzed the market circulation specifications being implementing of Polygalae Radix, combined with the modern quality evaluation methods to explore the effects of strains and base, origin and climate, growth duration and harvesting period and medicinal parts on the quality of P. tenuifolia. This paper reveals the correlation between the traits and quality of Polygalae Radix, furthermore, provides the theoretical basis for setting up the commodity specifications of Polygalae Radix, and determines the future research direction of P. tenuifolia quality assessment.

Analysis on rationality of medicinal product commodity specifications from determination of chemical components in Astragalus Radix / 中草药

By summarizing the results of the determination of index chemical composition in the samples of product specification and growth period of Astragalus Radix, we analyze the reason for the contradictions of determination results as follows: The actual growth years of the sample are not clear, the test samples mixed, and we draw the conclusion that the existing commodity classification is not scientific. Proposing a set of methods to identify actual growth years of Astragalus Radix and to carry out the research by comparing the chemical and biological effects with the subjects which we have known the exact growth years. Aiming to get the exterior features associated with its chemical compositions and biological effects to interpret the meaning of "assessing the quality by distinguishing the features of CMM". Finally, to establish the kinds of standards that not only embody the actual growth years of Astragalus Radix, but also for applicable to market transactions
