Title: Determination of Ursolic Acid in Xialian Granules by HPLC
Abstract: Objective To determination the content of ursolic acid in Xialian granules by HPLC. Method The mobile phase was methanol-water-acetic acid (90∶10∶0.04). The UV detection wavelength was 220nm, Shim-pack ODS (4.6mm×150mm) separation column. Result A good linearity was obtained in the range of 10~50μg, regression:A=439.3+2371544.7C (r=0.9967), the average recovery was 100.77%. RSD was 1.04% (n=6). Conclusion The method is good for determining ursolic acid in the Xialian granules.
