The Mobile phase was methanol- 0.15% phosphoric acid (88∶12), and the flow rate was 1.0 mL/min. Detection wavelength was 215 nm. Column temperature was room temperature. Results Ursolic acid quantity and its peak area showed good linearity relationship in the range of 0.253~5.052 ?g. The correlation coefficient (r ) was 0.9998 (n=6). The average recovery was 100.37% and RSD was 1.88%. Conclusion The method is easy and accurate, with good sensitivity and repeatability.
