Quality inspection method of cough pills

Abstract

The invention relates to a quality inspection method of cough pills prescribed in Volume 11 of Drug Standard of Ministry of Public Health of the People's Republic of China (Chinese Traditional Patent Formulation Preparations). The quality inspection method comprises microscopic identification of cough pills, a thin-layer chromatography identification method of ephedrine hydrochloride, magnolol and dried orange peel, a thin-layer chromatography qualitative identification method of bitter orange and a content determination method of ephedrine hydrochloride in the cough pills. The quality inspection method raises the quality control standards of cough pills and establishes content determination inspection indexes of main drugs in a preparation and a inspection method thereof; and meanwhile, the quality inspection method deletes physical and chemical reaction identification of poor specialization and adds the thin-layer chromatography qualitative identification method of ephedrine hydrochloride, magnolol, dried orange peel and bitter orange, thereby ensuring a higher quality standard level of compound preparations of cough pills.
