Abstract:Objective To establish a reversed -phase HPLC method for determination of sennoside A in Xiaochengqi decoction. Methods Chromatographic condition were: using SinochromC18 column (250mm×4.6mm) , 60% acetonitrile containing 12.4% acetic acid as mobile phase with 1.0ml·min^-1 of flow rate, detecting at 350nm. Results The calibration curve was linear in the range of 0.2 -1.0 μg. The regression equation was Y=12472X+265 (r=0.9995) .Conclusions This method is accurate ,simple and sensitive ,and can be used for the quality control of Xiaochengqi decoction.
Keywords:HPLC  Xiaochengqi decoction  sennoside A
