A method for monitoring and analyzing the quality of Chinese medicine raw materials

Abstract

The present invention discloses a method for monitoring and analyzing the quality of Chinese medicine raw materials, and relates to the technical field of quality monitoring and analysis. Different types of Chinese medicine raw material samples are collected, and the Chinese medicine raw material samples are pretreated respectively. A scientific experimental method is established by mass spectrometry and chromatography to study the composition of new Chinese medicine products and qualitative and quantitative studies of impurities; a suitable detection method is developed for impurities existing in new Chinese medicine preparations and raw materials and analyzed; characteristic spectra or fingerprint spectra in new Chinese medicine preparations and raw materials are studied, and qualitative and quantitative studies of impurities are conducted. The present invention pretreats the Chinese medicine raw material samples, obtains historical impurity data of the Chinese medicine raw material samples, performs spectral analysis and mass spectrometry analysis, studies the composition of new Chinese medicine products, and uses repeated spectral analysis and chromatographic analysis operations to qualitatively and quantitatively analyze the impurities existing in new Chinese medicine preparations and raw materials and evaluate the quality of Chinese medicine raw materials.
