Abstract

The invention relates to a method for rapidly detecting a concentration process of an extracting solution during preparation of Qizhiweitong granules with NIRS (near infrared spectroscopy) and an application. An NIRS online analysis method for the concentration process of the extracting solution during preparation of the Qizhiweitong granules is established and applied to online detection, and automatic detection of the concentration process of the extracting solution during preparation of the Qizhiweitong granules and real-time prediction of content of various quality control indexes are realized; an established model is high in prediction precision and accuracy and meets the requirement of quantitative analysis in actual production; compared with the traditional pharmacopoeia method, the method has the advantages that the analysis efficiency is increased greatly on the basis of accuracy, and the quality of the concentration process of the extracting solution can be monitored and controlled in real time rapidly and efficiently, so that the safety, the stability and the effectiveness of the final product quality are 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 concentration process of an extract in the preparation process of qi stagnation stomach pain 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 col...
