Objective:Quantitative determination of Baicalin in Xiaochaihu Granule by RP-HPLC.Method:Baicalin was extracted with methanol by an ultrasonic wave.Chromatographic conditions were as follows:Alltima C 18 column(250mm×4.6mm,5μm);Mobile phase:methanol-water-phosphoric acid(60∶40∶0.2);Column tempareture:the temperature of laboratory;Detection wavelength:280nm.Result:The standard curve was linear in the range of 0.06～0.60μg.The average recovery rate and RSD were 100.23% and 1.70% respeclively.(n=5).Conclusion:This method is rapid,reliable.It is suitable for quality control of the production.
