The invention discloses a method for detecting the quality level of traditional Chinese medicine. According to the technical scheme of the present invention, by establishing the relationship between the main components of traditional Chinese medicine and the in vitro activity, the quality control index components of Chinese medicine and the level of in vitro activity related to drug efficacy are determined, and the clustering status of samples is determined by principal component analysis. A large number of sample data of different batches of traditional Chinese medicines were used to construct a logistic regression model between quality grades, index components, and biological activities, and to establish corresponding formulas for the detection of grades of Chinese medicinal materials. The Chinese medicine grade detection method proposed by the present invention can realize the mathematical expression of the quality difference standard of Chinese medicine, and finally can provide a feasible solution path for industrial evaluation of the quality grade of medicinal materials or decoction pieces. |
