Objective:To develop an HPLC method for analysis of emodin and chrysophanol in Tuizhang Hydrogel.Method:The emodin and chrysophanol in Tuizhang Hydrogel were separated on a Chromasil C18 column(4.6 mm×250 mm
5 μm) eluted with the mobile phase of methanol-0.1% Phosphoric acid(82∶18).The flowrate was 1.0 mL·min-1
and the UV detector wavelenghth was set at 254 nm.Results:The calibration curves were linear over the concentration range of 0.025~0.125 μg for emodin and 0.072~0.360 μg for chrysophanol.The recoveries of the emodin and chrysophanol were 99.1%
99.2%
respectively.Conclusion:The method was simple and accurate
it can be used for the determination of emodin and chrysophanol in Tuizhang Hydrogel.
