Title: Determination of Ursolic Acid in Xiasangju by HPLC after Pre-derivazation with p-Toluidine
Abstract: The method of the HPLC determination of ursolic acid in Xiasangju was developed using methanol-water (80∶20,V/V) containing 10 mmol/L pH 6.2 HAc-NaAc buffer as the mobile phase with the detection at 290 nm. The ursolic acid was linear over the range of 0.3~30.0 mg/L(r=(0.9987)). The detection limit was 2.46 μg/L. The average recovery was 101.2%(n=5). The method is accurate and suitable for the qualify control.
