Problems solved by technology

[0003] Due to the complexity of the matrix in Chinese patent medicines, ingredients such as flavonoids, alkaloids, and polysaccharides are likely to interfere with the detection. The sensitivity and accuracy of traditional Chinese medicine detection methods such as thin-layer chromatography and high-performance liquid chromatography are not ideal. Therefore, it is necessary to provide a detection method suitable for various chemical complex components

Abstract

The invention discloses a method for detecting the addition of chemical components in a Chinese patent medicine. The method comprises the steps of preparing a standard solution from chemical components to be detected, drawing a standard curve, preparing a sample solution from a Chinese patent medicine sample to be detected, determining by liquid chromatography-tandem mass spectrometry, and comparing with the standard solution to perform qualitative and quantitative analysis. By optimizing the treatment process of the sample and the standard substance and accurate chromatographic and mass spectrometric conditions, detection of multiple added functional chemical components in the Chinese patent medicine is realized, the sample can be qualitatively and quantitatively processed on a machine only by dilution and filtration treatment, the tedious steps of conventional dispersive solid-phase extraction and the like are greatly simplified, meanwhile, the detection time is relatively short, consumable consumption is low, and powerful technical support is provided for quality detection of the Chinese patent medicine.

Description

technical field [0001] The invention belongs to the technical field of traditional Chinese medicine detection, in particular to a detection method for adding chemical components in Chinese patent medicines. Background technique [0002] Chinese patent medicines are made of traditional Chinese medicinal materials. Under the guidance of the theory of traditional Chinese medicine, in order to prevent and treat diseases, according to the prescribed prescription and preparation process, they are processed into certain dosage forms of traditional Chinese medicine products, which are approved by the State Drug Administration Department. A class of commercialized traditional Chinese medicine preparations. Since each medicine in the prescription contains a variety of chemical components, and some chemicals are added in order to improve the efficacy of the medicine, these chemical components are the material basis for the compound prescription to exert its medicinal effect, but any ac...
