Abstract

Objective:To establish a determination method for the content of Emodin and Chrysophanol in shenshuaining tablet Methods:The HPLC system column.mobile phase CH3OH-0.025mol/LH3PO4 85∶15)mixture.With detection wave at 254nm,it was used to determine the content of Emodin and Chrysophanol in the tablet.Results:Recovery of 95.3～99.8% RSD=1.08% for Emodin were obtained.Recovery of Chrysophanol 95.1～99.5% RSD=1.76%.Conclusion:The method is sensitive and accurate with great reproducibility.
