Abstract：Cayratia Japonica herbs were used for discussing the effects of the extract temperature,time, ratio of material to solvent and ethanol concentration on the yield of Cayratia Japonica polyphenols with single factor and orthogonal experiments.The measure of Folin-ciocalteu was applied to test the content of polyphenols,and the results show the influence level was that:D(extract temperature)>A(ethanol con-centration)> C( time)> B( ratio of material to solvent). The best extraction process combination is A2 B3 C2 D2 ,namely extract temperature 60℃ ,ethanol concentration 60% ,extract time 1 hour and ratio of material to solvent 1 ∶ 70.The polyphenols from Cayratia Japonica yield 0.89%.
