Abstract

The invention discloses a detection method for compounded Sichuan fritillary bulb extract tablets. The detection method comprises the steps of carrying out character detection, carrying out microscopic observation, carrying out thin-layer chromatography qualitative identification and carrying out content determination, wherein thin-layer chromatography qualitative identification comprises the steps of identifying ephedrannin and neoephedrine A in a preparation, identifying polygala root and cynanchum atratum and identifying glycyrrhiza uralensis; content determination comprises the step of determining the content of ephedrine hydrochloride in the preparation. The detection method disclosed by the invention has the advantages that the mixing of radix ephedrae and cynanchum atratum is effectively controlled, and meanwhile, the composition and content of the compounded Sichuan fritillary bulb extract tablets are effectively controlled, so that the drug can be safer and more effective.

Description

technical field [0001] The invention relates to a method for detecting medicines, in particular to a method for detecting compound Chuanbeijing tablets. Background technique [0002] Compound Chuanbei Jing Tablets is a variety recorded in the nineteenth volume of traditional Chinese medicine preparations in the "Drug Standards of the Ministry of Health". The standard number is WS-B-3622-98. Mother, polygala (remove licorice root), tangerine peel, French pinellia, bellflower, licorice extract, are tablets made of pure traditional Chinese medicine. It has the functions of resolving phlegm and relieving cough, relieving lung and relieving asthma. It is clinically used to treat acute and chronic bronchitis, bronchiectasis, cough, phlegm and dyspnea caused by phlegm blocking the lung and lung failure. However, in the original standard, only the microscopic identification of Pinellia chinensis was carried out, and the identification of ephedra by TLC was carried out. There was n...
