Problems solved by technology

[0003] The quality control methods of traditional Chinese medicine and Chinese medicine preparations in my country are mostly microscopic identification, thin-layer identification and content determination of single component types, which cannot accurately and comprehensively control product quality
The various components and various excipients of traditional Chinese medicine preparations will interfere with quality testing in many ways. If the sample pretreatment procedures are not scientifically verified, it is likely to cause inaccurate test results.

Abstract

The invention relates to a quality control method for Huang's sound pill. The quality control method employs liquid chromatography to perform content determination, and the content processes comprises determination processes for free anthraquinone, combined anthraquinone, forsythol, ferulic acid and glycyrrhizic acid. The quality control method is sensitive and fast, is capable of timely accurately reflecting the quality of nonvolatile main compositions in Huang's sound pill and improving production monitoring level, and has more practical application meaning in industrial production.

Description

technical field [0001] The invention relates to a quality control method of Huangshi Xiangsheng pill preparation. technical background [0002] Huang's Xiangsheng Pills are developed based on nine generations of ancestral secret recipes dedicated by the chief physician Huang Shennong, a famous old Chinese doctor of laryngology. It can be used to treat acute and chronic laryngitis, vocal cord nodules, vocal cord polyps, and constipation. Its quality standards are recorded in the "Chinese Pharmacopoeia" 2010 edition, page 1064, in which the identification tests include rhubarb, Chuanxiong, and licorice, and the content determination detects peimin A and peimin B in Fritillaria japonicus. [0003] The quality control methods of traditional Chinese medicine and Chinese medicine preparations in my country are mostly microscopic identification, thin-layer identification and content determination of a single component type, which cannot accurately and comprehensively control produc...
