[Objective] The aim was to establish a method for the content determination of catechin in Embelia parviflora Wall..[Methods] UV Spectrophotometry was adopted to determine content of catechin at the detection wavelength of 280 nm.[Results] The absorbance and concentration of catechin showed a good linear relationship when the concentration ranged from 0.007 81 mg/ml to 0.046 86 mg/ml(r=0.999 2)with average recovery of 98.72% and RSD value of 0.09%(n=5).Mean content of catechin in Embelia parviflora Wall.was 2.88%.[Conclusion] This method was simple,rapid and accurate,and could be used for the quality control of catechin in Embelia parviflora Wall.
