Abstract

The present invention provides a fingerprint detection method of Danshu capsule. The method using a gas chromatography detection method with the initial temperature of 73 DEG C-75 DEG C, and the terminal temperature of 160 DEG C-200 DEG C; programming temperature rises is employed; the inlet temperature is at 250 DEG C, and the detector temperature is at 250 DEG C; and a sample solution prepared from Danshutong capsule contents is detected. The detection method can detect a plurality of components, has good separation on the components, can provide effective standards for quality control of Danshutong capsule; the overall peak time is short, thereby greatly reducing the detection time and cost; and the method is more conducive to industrial applications.

Description

technical field [0001] The invention relates to the field of drug detection, in particular to a fingerprint detection method of Danshu capsules. Background technique [0002] Mint is widely distributed in various parts of my country, such as Yunnan, Jiangsu, Zhejiang, Jiangxi, etc. are all produced. China is one of the main export countries of peppermint oil and menthol. Peppermint oil (OleumMenthaeDementholatum) is the main chemical component in Peppermint. It is a traditional Chinese medicine, which has the effects of cooling and relieving itching, anti-inflammatory and analgesic, expectorant, choleretic, and stone-dissolving [Liu Hongjie et al., Peppermint Oil Research Progress, Shandong University of Traditional Chinese Medicine Journal 2006, 30(6): 502-505], mainly used clinically to treat chronic cholecystitis [Han Jie et al., Clinical Observation of 25 Cases of Chronic Cholecystitis Treated by Danshu Capsules, Chinese Patent Medicine, 2007, 29(1): instruction manual...
