Objective: To establish the quality standard for Erxiaqingxin Tablets(Cordyceps, Rhizoma Pinelliae, Radix Puerariae, Caulis Bambusae in Taenia, Fructus Aurantii Immaturus, Pericarpium Citri Reticulatae, etc.). Methods:TLC was performed to identify Pericarpium Citri Reticulatae, Fructus Aurantii Immaturus and Radix Puerariae. HPLC was used to determine the content of puerarin. Results:The study on the quality control showed that the characteristic of identification by TLC was distinct and hightly specific. The quantification method had the linear range of 0.04092～2.4552?g. The average recovery was 99.36% and RSD was 2.32%. Conclusion:The method for identification and quantification was simple, realizable and reproducible. It can be used effectively for the quality control of Erxiaqingxin Tablets.
