Abstract

The invention relates to a method for determining the content of compound Caoshanhu lozenge prepared from glabrous sarcandra herb extractum, menthol and dementholised peppermint oil. The thin-layer chromatography is used for distinguishing the menthol and the glabrous sarcandra herb extractum in the lozenge. The method is characterized in that the high performance liquid chromatography is used forsimultaneously determining the content of two marker components, including isofraxidin and rosmarinic acid in the lozenge under the chromatographic condition of isocratic elution; or the high perform ance liquid chromatography is used for simultaneously testing the content of four marker components, including protocatechuic acid, caffeic acid, the isofraxidin and the rosmarinic acid in the lozengeunder the chromatographic condition of gradient elution.

Description

technical field

[0001] The invention relates to a method for determining the content of a compound traditional Chinese medicine preparation, in particular to a method for determining the content of a compound Chinese medicine grass coral buccal tablet. Background technique

[0002] The compound grass coral buccal tablets recorded in "Pharmacopia of the People's Republic of China" (2005 edition one) is a traditional Chinese medicine compound preparation prepared from sargassum extract, menthol, and peppermint oil. [Preparation method] the above three flavors, Zhongjiefeng extract is taken from Zhongjiefeng, add water and decoct twice, the first time is 2 hours, the second time is 1.5 hours, combine the decoction, filter, the filtrate is concentrated to a relative density of 1.15 (80°C), add ethanol When the alcohol content reaches 65%, let stand for 24 hours, filter, recover ethanol from the filtrate under reduced pressure, and concentrate it into a clear paste with a relativ...
