Abstract

The invention relates to a method for quickly detecting a water extraction process during the preparation of Qizhiweitong granules by use of near-infrared spectroscopy and application. According to the invention, a near-infrared spectroscopy online analysis method is established for a water extraction process during the preparation of Qizhiweitong granules and applied to online detection, and automatic detection of the water extraction process during the preparation of Qizhiweitong granules and real-time prediction of various quality control index content are realized; the established model has high prediction precision and high accuracy and meets the requirements of quantitative analysis in practical production; and compared with a traditional pharmacopeia method, the method has the advantages that the analysis efficiency is greatly improved on the basis of guaranteeing accuracy, and the quality of the water extraction process can be quickly and efficiently monitored and controlled in real time, so that the safety, stability and effectiveness of the final product quality can be guaranteed.

Description

technical field [0001] The invention belongs to the field of drug detection, and specifically relates to a method and application for rapidly detecting the water extraction process in the preparation process of Qi stagnation Weitong granules by using near-infrared spectroscopy. Background technique [0002] Qi stagnation stomach pain granules are made of 6 traditional Chinese medicines of Bupleurum, Corydalis Corydalis, Fructus Citrifolia, Cyperi Cyperi, Radix Paeoniae Alba and Radix Glycyrrhiza. The treatment of epigastric pain and other diseases has become the first-line drug for clinical treatment of epigastric pain after years of clinical practice. However, the preparation process of Qizhi Weitong Granules is complex and cumbersome, and slight changes in various process parameters in the actual production process may directly affect the quality of the final drug. [0003] Traditional drug analysis techniques generally use off-line analysis methods to collect liquid medi...
