Objective:Unify and improve the quality standard of xinmaitong capsule.Methods:Using thin layer chromatography(TLC)for identification of Cassiae semen and Sophorae flos,and the contents of ferulic acid and puerarin were determined by high-performance liquid chromatography chromatography(HPLC).Results:The TLC spots were clear,the resolution was good,and the specificity was strong.The linear relationship between ferulic acid and puerarin is good within their respective ranges(r≥0.999).The average recovery rate of ferulic acid is 100.3%,RSD=2.0%(n=6),and the average recovery rate of puerarin is 99.0%,RSD=0.4%(n=6).Conclusion:The quality standard established in this experiment are scientific,comprehensive,and feasible,which can be used for the quality control of xinmaitong capsule.
