Abstract

The invention provides a quality control method for an extraction process of Chinese medicine ainsliaea fragrans champ, and the quality control method comprises the following steps: firstly, measuring the content of chlorogenic acid in a qualified ainsliaea fragrans champ extract solution and acquiring a near-infrared spectrum; secondly, respectively establishing a corresponding model between thenear-infrared spectrum and the content of the chlorogenic acid in the ainsliaea fragrans champ extract solution by adopting chemometric software; thirdly, measuring the near-infrared spectrum of a chlorogenic acid sample of which the content is to be measured; and fourthly, by using the corresponding model, respectively acquiring the content of the chlorogenic acid in the chlorogenic acid sample of which the content is to be measured through the chemometric software.

Description

technical field [0001] The invention relates to the field of quality control of traditional Chinese medicines, in particular to a method for quality control of chlorogenic acid in the production process of extracting and producing traditional Chinese medicine Xingxiang rabbit's ear wind. technical background [0002] Traditional Chinese medicine is one of the most original and independent intellectual property industries in China. Chinese patent medicines and decoction pieces are the main forms of clinical application of traditional Chinese medicine. Due to the complexity of the material basis of the curative effect of traditional Chinese medicine, the technical means of quality control in the production of Chinese patent medicine are relatively extensive, which is reflected in the quality control of Chinese patent medicine using process control, coupled with the quantitative detection of representative chemical index components and the qualitative preparation of preparation...
