Abstract: The effects of ratio of raw material to liquid,microwave time,microwave power,ethanol concentration on the extraction rate of polyphenols from rotten jujube peel were investigated,and a predictive polynomial quadratic model was set up by means of central composite design to optimize the microwave extraction parameters of polyhneols from rotten jujube pell.The optimal conditions of microwave extraction are concluded as follows:ratio of raw material to liquid 0.035 g/ml,microwave treatment time 57.94 s,microwave power 450 W and ethanol concentration 40.30%.
