The invention provides a quality control method for a rhubarb (a traditional Chinese medicine) ethanol-extraction process, which is characterized by comprising the following steps: 1, measuring the specific weight and the emodin content of a qualified rhubarb ethanol-extracting solution, and acquiring the near infrared spectrum of the qualified rhubarb ethanol-extracting solution; 2, respectively building a corresponding model between the near infrared spectrum and the specific weight and a corresponding model between the near infrared spectrum and the emodin content of the rhubarb ethanol-extracting solution by using chemometric software; 3, measuring the near infrared spectrum of a rhubarb ethanol-extracting solution sample to be measured; and 4, by using the corresponding models, respectively acquiring the specific weight and the emodin content of the rhubarb ethanol-extracting solution sample to be measured by using the chemometric software.
Description
A kind of quality control method of ethanol extraction process of traditional Chinese medicine rhubarb technical field The invention relates to the field of quality control of traditional Chinese medicines, in particular to a method for controlling the specific gravity and emodin quality of Chinese medicine rhubarb ethanol in the production process. technical background 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 c...
