The polyphenols of Pistacia chinensis seeds was extracted by conventional solvent. By comparing extract yield of different solvent to determine ethanol was the best one. On this basis, the extraction conditions of polyphenols from Pistacia chinensis seeds were optimized by single factor experiments and response surface methodology(RSM). The results showed that the optimum extract conditions as follows:ethanol concentration of 64.51%(V/V),extract time of 41.32 min, material–liquid ratio of 1∶32.09(W/V),extract temperature of 46.1℃and extract twice. Under these conditions,the polyphenols extract yield was(4.43±0.02)%.
