Abstract

The invention discloses a method for monitoring quercetin in the extraction process of folium ginkgo in real time by applying a near-infrared technology. The method comprises the following steps: firstly installing a macroporous-resin real-time monitoring system, then carrying out correlation on the content data of the quercetin determined by a high-performance liquid chromatography and near-infrared spectral information by applying a partial least square method, and establishing a quantitative correction model for the content of the quercetin in the extraction process of the folium ginkgo; utilizing the established quantitative correction model to carry out fast detection on the content of the quercetin in the extraction process of the unknown folium ginkgo. The method disclosed by the invention has the advantages that real-time sampling can be carried out on an extracting solution in the extraction process of the folium ginkgo, and the change of the quercetin in the extracting solution of the folium ginkgo is monitored in real time; and the result is accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of separation and purification of traditional Chinese medicines, and in particular relates to a method for real-time monitoring of quercetin in the extraction process of ginkgo leaves by using near-infrared. Background technique [0002] In the pharmaceutical process of traditional Chinese medicine, the extraction process, as one of the characteristic links in the production of traditional Chinese medicine, determines the proportion of different components in the finished product in traditional Chinese medicine, that is, determines the curative effect of the medicine. At present, the quality control of the extraction process of traditional Chinese medicine in my country is still very passive. Only the quality inspection of the end product is carried out, and the composition changes in the process are rarely considered. It is difficult to accurately control the production process, resulting in large quality di...
