Title: Determination of Oleanolic Acid in Xinkeshu Capsule by HPLC
Abstract: A HPLC method was established for the determination of oleanolic acid in xinkeshu capsule.The Hypersil ODS C18 column(250mm×4.6mm,5μm) was used,and the mobile phase was methanol-acetonitrile-water(79∶5∶16,V/V/V) at the flow rate of 1.0mL/min with column temperature of 30℃,and the detection wavelength of 210nm.The linear range of oleanolic acid was 2.04—81.6μg/mL(r=0.9998) with the average recovery of 100.54%.The method was simple and accurate,It could be used for controlling the quality of xinkeshu capsule.
