ABSTRACT
Objective:
To establish a method for HPLC determination of ursolic acid in Kangzhitong Jiangzhi Capsule.Methods:
HPLC,chromatographic column Kromasil C18(4.6mm?250 mm,5?m)and the mobile phase consisted of methyl alcoholwater-ammonium acetate-acetonitrile(9∶25∶0.8∶65) were used to find ursolic acid.The flow rate was 1.0ml?min and the detector wave-length was set at 215nm.Results:
The calibration curve was in good linearity over the range of 64-320?g/ml(r=0.9996).The average recovery rate was 100.10%,with RSD=1.32%.Conclusion:
This method is simple,accurate and reproducible so it can be used to determine the content of ursolic acid in Kangzhitong Jiangzhi Capsule.
