Abstract

The invention provides an HPLC (high-performance liquid chromatography) fingerprint spectrum measurement method for a standard Yunujian decoction, and belongs to the technical field of traditional Chinese medicine. The HPLC fingerprint spectrum measurement method includes (1), preparing a sample solution for test; (2), preparing a mixed reference substance solution; (4), accurately sucking the sample solution for test and the mixed reference substance solution, and injecting the solutions into a high-performance liquid chromatograph for measurement to acquire liquid chromatograms of the samplesolution for test and the mixed reference substance solution; (5), matching data of the liquid chromatograms of the sample solution for test and the mixed reference substance solution by traditionalChinese medicinal chromatography fingerprint spectrum similarity evaluation system software made by Chinese Pharmacopeia Commission to acquire a standard fingerprint spectrum. The HPLC fingerprint spectrum measurement method for the standard Yunujian decoction has the advantages that quality of standard Yunujian particles is controlled effectively, curative effect of the medicine is guaranteed, and the classic prescription is enabled to be under standard quality control.

Description

technical field [0001] The invention relates to the technical field of traditional Chinese medicines, in particular to an HPLC fingerprint determination method of Yunvjian Standard Decoction. Background technique [0002] As the main dosage form of traditional Chinese medicine clinical medicine, decoction of classic prescriptions of traditional Chinese medicine has the advantages of reasonable composition, definite curative effect, easy absorption, and quick onset of effect, and is deeply trusted by patients. However, due to the shortcomings of deployment, carrying, temporary decoction, and long-term storage, it is prone to mildew and deterioration, the soup tastes bitter and the volume is large, and the standard is difficult to unify, which seriously affects its clinical efficacy. It cannot adapt to the living requirements of modern people. In order to maintain the advantages of the decoction and overcome the various deficiencies of the decoction, under the strong support o...
