Abstract

OBJECTIVE To establish the method for quality control of Yangchun tablets.METHODS Epimedii,ursolic acid were indentified by TLC.The content of epimedii was determined by HPLC.RESULTS The spots of TLC were distinct,the negative sample had no interference.The linear regression for icariin was obtained over the range of 20～1 000 ng(r=0.999 9).The average recovery was 99.12%,RSD=1.67%(n=6).CONCLUSION The established method is simple,feasible and repeatable,and can be used for the quality control of Yangchun tablets.
