Objective:To establish the determination method for oleanolic acid in dandelion by HPLC. Method: HPLC was carried out on Hypersil ODS2 C18 (4. 6 mm × 250 mm
5 μm) at 30 ℃ using methanol-0. 5% H3PO4 (pH = 3. 5)(90∶ 10) as mobile phase with a flow rate of 1. 0 mL·min -1 and detection wavelength was at 210 nm. Result:The oleanolic acid was linear within the range of 0. 872 ~ 7. 848 μg. The average recovery was 98. 25% and RSD was 1. 54% . Conclusion:This method is useful for quality control of dandelion.
