| Abstract: | Objective：To establish a HPLC method for the determination of oleanolic acid in achyranthes produced in Sichuan.Methods：The separation was carried out on the Dikma Kromasil C18 column（250 mm×4.6 mm,5 μm）.The mobile phase was methanol-water（92：8）.The detective wavelength was set at 210nm.The column temperature was 30℃ and the flow rate was 1.0 mL·min-1 with the sample volume of 10μL.Results：The calibration curve showed good linearity over the range of 1-10 μg（r=0.9999）.The average recovery rate was 96.97% with RSD 1.02%.Conclusion：This method is simple,rapid,accurate with good repeatability and good recovery,which can be used as the quantitative analysis method of oleanolic acid for achyranthes produced in Sichuan. |
