Problems solved by technology

[0003] In the standard of Jinji Capsules, there are too few index components for content determination, and the only determination component is berberine hydrochloride, which is difficult to effectively guarantee product quality, so it is necessary to establish multiple index components for quality control
The patent with the application number 200510200479.4 discloses the content determination method of andrographolide and dehydroandrographolide in Jinji capsules, but this method cannot effectively remove interfering impurities, and the separation of chromatographic peaks and miscellaneous peaks is not good

Abstract

The invention discloses a method for controlling quality of a Jinji preparation. The method adopts the high performance liquid chromatography, has good precision, stability and reproductivity and can effectively control the quality of the Jinji preparation products.

Description

field of invention [0001] The invention relates to a quality control method of a pharmaceutical preparation, in particular to a method for determining the content of a golden rooster preparation for treating gynecological diseases. Background technique [0002] Jinji Capsule is a marketed drug with approval number Z45020293. It has the functions of clearing heat and detoxifying, invigorating the spleen and dehumidification, dredging collaterals and activating blood circulation, and is used for adnexitis caused by damp-heat betting. This product is extracted and refined from medicinal materials such as Rosa root, Millipede Spatholobus, Qianjinba, Gongluomu, LMianzhen, andrographis paniculata. Gonglaomu has the effect of clearing away heat and dampness, purging fire and detoxifying. It is commonly used in folks for clearing away heat, detoxifying, and treating colds. Its main active ingredients are alkaloids, mainly berberine hydrochloride, palmatine hydrochloride and jatrorrh...
