Abstract

The invention discloses a detection method for traditional Chinese medicine preparation compounded Sichuan fritillary bulb extract tablets. The detection method comprises the steps of 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 the preparation, identifying polygala root and cynanchum atratum and identifying glycyrrhiza uralensis and schisandra fruit; 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 is effectively controlled, so that the drug can be safer and more effective.

Description

Technical field [0001] The invention relates to a method for detecting drugs, in particular to a method for detecting compound Chuanbeijing tablets of traditional Chinese medicine preparations.
