Abstract

OBJECTIVE To establish a method for determination of emodin and Chrysophanol in Kuipingning particles by HPLC.METHODS A Zobax SB-C18 column was used.The mobile phase was Methanol-0.1% phosphoric acid(80∶20) and the detection wavelength was 254nm.RESULTS The linear range for emodin and Chrysophanol was 0.02056～0.2056μg、0.02616～0.2616μg(r=0.9999).The average recovery was 99.9%、99.5%(n=6),RSD=1.2%、RSD=1.7%.CONCLUSION The method used for the determination of emodin and Chrysophanol in Kuipingning particles is simple,timesaving and accurate.
