Abstract

Objective: To establish the quality standards of Pingweishu capsules.Method: Coptis chinensis and Corydalis Rhizoma were identified by TLC.The content of berberine hydrochloride was determined by RP-HPLC.Result: The spots in the TLC were fairly clear,and no interference was shown in the blank samples.Berberine hydrochloride showed a good linear relationship within a range of 0.368-3.68 μg(r = 0.999 8).The average rate of recovery was 99.86%(RSD 1.46%).Conclusion: The method is a simple,rapid and accurate analysis assay,which could be used for quality control of Pingweishu capsules.
