Objective:To develop an HPLC method for the determination of harpagoside in Xiaoerqingyan granule.Method:Samples were separated on a Dikma Diamonsil C18 colum with the mobile phase of methanol-water(45∶55~70∶30
0~40 min) and the detection wavelength was set at 278 nm.Result:The calibration curve was linear in the range of 2.944~88.32 μg/ml(r=0.999 9) for harpagoside.The average recovery was 100.5%
RSD=2.78%(n=9).Conclusion:The method is accurate and has good reproducibility.It can be used for quality contral of Xiaoerqingyan Keli.
