Abstract
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.
