Abstract:
OBJECTIVE:To establish a method for the content determination of L-epicatechin in Actinidiae arguta. METHODS:HPLC was performed on the column of Kromasil C18 with mobile phase of acetonitrile-0.2%Acetic acid solution(15:85,V/V)at a flow rate of 1.0 ml/min,detection wavelength was 210 nm,column temperature was 25 ℃,and the volume injection was 10 μl. RESULTS:The linear range of L-epicatechin was 10.47-167.52 μg/ml(r=0.999 9);RSDs of precision,stability and reproducibility tests were lower than 2%;average recovery was 98.07%-101.71%(RSD=1.39%,n=6). CONCLUSIONS:The method is simple, accurate and reliable,and suitable for the content determination of L-epicatechin in A. arguta.
