Abstract:Objective To establish a method for the content determination of 12, 13-dihydroxyeuparin in Complex Radix Eupatorii Chinensis Mixture by HPLC.Methods HPLC was developed to determine 12, 13-dihydroxyeuparin with UV absorptions at 240nm. The analysis was performed on a Kromasil C18 column (250mm×4.6mm,5μm)with a gradient solvent system of acetonitrile and 0.1%aqueous phosphoric acid at a flow rate of 1.0mL·min-1. Results There was a good linear relationship (r2=0.9945)in the range of 0.00414~0.02484mg·mL-1. The mean recovery was 95.87%, RSD was 2.60%(n=6). Conclusion This method is simple,sensitive and accurate,and can be used for quality control of Complex Radix Eupatorii Chinensis Mixture.
Keywords:Radix  Eupatorii  Chinensis Mixture 12,13-Dihydroxyeuparin  HPLC
