Problems solved by technology

[0005] At present, there is no quality control method for simultaneously measuring ginkgolide A, ginkgolide B, and ginkgolide K in ginkgolide pharmaceutical preparations. The present invention proposes a method that can effectively control the quality of ginkgolide injection, including After adjusting the pH of the injection to be acidic and acidified so that the lactones are all converted into lactones, the method of simultaneously measuring the contents of ginkgolide A, ginkgolide B and ginkgolide K is also proposed to directly test the free ginkgolide without acidification. A, ginkgolide B, ginkgolide K carry out the method for limited inspection and the method for fingerprint chromatogram determination, the method provided by the invention can reach the purpose of more comprehensively and effectively controlling the quality of ginkgolide injection preparations

Abstract

The invention relates to a quality control method of medicinal preparation, in particular to a quality control method of ginkgolide medicinal preparation. The invention provides a method for controlling the quality of the ginkgolide medicinal preparation by adopting high performance liquid chromatography. The method can control the quality of the ginkgolide medicinal preparation by adopting one ormore of a content determination method, a limit test method of dissociation ginkgolide and a chromatographic fingerprint method. The quality control method provided by the invention has the advantages of having high precision, stability and repeatability, and achieving the aim of effectively controlling the quality of the ginkgolide medicinal preparation in an all-round way.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine analysis, and relates to a quality control method of traditional Chinese medicine preparations, in particular to a quality control method of ginkgolide pharmaceutical preparations. The quality control method includes a content determination method, a limit inspection method and a fingerprint spectrum determination method. technical background [0002] Ginkgolides are a group of terpenoids with strong biological activity contained in Ginkgo Leaf. The isolated ones include ginkgolides A, B, C, J, M, K, L and Bilobalides have been found to be strong antagonists of the vascular activating factor (PAF) and have good application prospects. BN52063 (Ginkgolide Mixture) and BN52021 (Ginkgolide B) have entered the clinical trial stage abroad. [0003] Ginkgolide pharmaceutical preparations are injections made from total ginkgolides, the main component of which is ginkgolide A (C 20 h 24 o 9 ...
