        【Abstract】 Objective To establish the HPLC metnod for determination of Emodin, Rheochrysidin and Quercetin in Burn tincture. Methods The Hypersil ODS C 18 was used as the stationary phase. The mobile phase consisted of methanol-phosphate buffer(pH=4)(65:35).The Detecting wavelength was 254nm and flow rate was 1.0 ml/min.Results The linear range of emodin, rheochrysidin and quertetin were 0.7~7.0 μg/ml, 0.504~5.04 μl/ml, 0.384-3.84 μl/ml respectively. The recovery rates of emodin, rheochrysidin and quercetin were 98.65%(RSD=1.24%),98.70%(RSD=1.08%),99.36%(RSD=1.54%) respectively. Conclusion This method is realiable and accurate, the method can be applied to determination of emodin, rheochrysidin and quercetin in Burn tincture.
