| Abstract: | Objective To establish a method for determination of ursolic acid in Xiasangju Granules by HPLC.Method A HPLC method was established by using a C 18 column (4.6 mm ×250 mm, 5 μm) as analytical column , MeOH-H 2O-HOAC-TEA (95∶5∶0.3∶0.02)as the mobile phase.The flow rate was 0.8 mL·min -1,and detection wavelength was 215 nm.Results The linearity was obtained at the range of 16.8～50.4 μg·mL -1 for ursolic acid(r =0.999 7).The average recovery was 97.58% with RSD 1.58%(n=5).Conclusion The method is easy and simple, accurate with good reppearance. |
