Method for identifying traditional Chinese medicinal materials and easily confused counterfeit medicines on the basis of ion mobility spectrometry and similarities

Abstract

The invention discloses a method for identifying traditional Chinese medicinal materials and easily confused counterfeit medicines on the basis of ion mobility spectrometry and similarities. The ion mobility spectrometry is used as an analysis and test means, quantification processes include similarity computation and quality control charts, and the quantification method applicable to controlling the quality of the traditional Chinese medicinal materials can be provided. The method has the advantages that the method gives priority to quantitative evaluation rather than qualitative analysis dominant in traditional quality control identification of the traditional Chinese medicinal materials and is speedy, accurate and capable of achieving quantitative output, so that a novel evaluation thought is provided for the quality safety of the traditional Chinese medicinal materials in China, and the method is of important significance to quality control guarantee and clinical medication safety of the traditional Chinese medicinal materials.

Description

Technical field [0001] The invention belongs to the technical field of identification of Chinese medicinal materials, and particularly relates to a method for identifying Chinese medicinal materials and their easily mixed and counterfeit products. Background technique [0002] Chinese medicinal materials are an important basis for the efficacy of Chinese herbal compound prescriptions. The mixing of fake products greatly affects the efficacy of the drugs and threatens the health of patients. Take the common Chinese medicinal material Codonopsis for example. Radix Codonopsis is Codonopsis pilosula (Franch) Nannf, Codonopsis pilosula (Franch) Nannf.Var.modesta (Nannf) LTshen or Codonpsis tangshen. The dried roots of oliv have the effects of nourishing the middle and nourishing qi, invigorating the spleen and lungs, but due to the shortage of wild party parameters, artificially cultivated products often cannot meet the market demand, resulting in frequent occurrences of fake products...

AI Technical Summary

Problems solved by technology

[0003] The common quality control and identification techniques of traditional Chinese medicinal materials mainly include the following two types of strategies, one is the source identification, character test and microscopic test, these test methods are artificial to a certain extent (Qian Yunchuan, Zhou Lemin, China Pharmaceutical Industry, 2001, 10 (5), 59. Li Xiaolin, Shao Aijuan, Zhan Xiaori, etc., Chinese Journal of Traditional Chinese Medicine, 2015, 40(7), 1271-1273.); the second is physical and chemical testing and instrumental analysis, but the test time is long and the instrument is expensive ( Zou Yuanfeng, Cao Chaosheng, Liu Jiang, etc., Chinese Herbal Medicine, 2010, 41(3), appendix 3-attachment 6)
