Abstract:Objective To establish a method for determining catechin and epicatechin in Qili San.Methods HPLC was used for the determination.The chromatographic column was Prevail Select C18(150 mm ×4.6 mm,5 μm)and the column temperature was 35℃.The mobile phase consisted of acetonitrile-water-phosphoric acid(100∶ 900∶ 1).The flow rate was 1 ml/min and monitored at 278 nm.Results The linear range of catechin was 30.08-150.4μg/ml,r=0.9999.The average recovery of catechin was 99.1% and RSD was 1.1%.The linear range of epicatechin was 12.24-61.20μg/ml,r=0.9999.The average recovery of epicatechin was 97.4% and RSD was 1.2%.Conclusion This method is simple,time-saving and accurate.It can be used for routine analysis of catechin and epicatechin in Qili San.
Keywords:HPLC  Qili San  catechin  epicatechin
