Abstract

Objective To establish the quality control standard of Yereqing Granule.Methods Herba Artemisiae Annuae,Cortex Moutan,Radix Puerariae Lobatae were identified by TLC and the content of paeonol was determined by HPLC.Results All components could be detected by TLC.Under the selected HPLC condition,paeonol was well separated from other constituents.The average recovery rate was 99.16%,RSD= 0.82%.Conclusion The methods are proved to be simple and special with a good reproducibility and can be used as the quality control of the preparation.
