Abstract

The invention provides a method for measuring the specific gravity and gardenoside content of gardenia percolate. The method comprises the following steps of: 1, measuring the specific gravity and the gardenoside content of the qualified gardenia percolate and acquiring a near infrared spectrum; 2, establishing a corresponding model between the near infrared spectrum and the specific gravity and the gardenoside content of the gardenia percolate respectively by using chemical metrological software; 3, measuring the near infrared spectrum of the gardenia percolate sample to be measured; and 4, obtaining the specific gravity and the gardenoside content of the gardenia percolate sample to be measured respectively by using the chemical metrological software through the corresponding model.

Description

technical field [0001] The invention relates to the quality control of traditional Chinese medicines, in particular to a method for controlling the specific gravity of the traditional Chinese medicine gardenia percolation liquid and the quality of geniposide in the production process. 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 of Chinese patent medicine are relatively extensive, which is reflected in the quality control of Chinese patent medicine adopts the control of process method, plus the quantitative detection of representative chemical index components and the qualitative inspection of preparations . That is, ...
