摘　　要： 研究了热浸法提取花生壳中多酚类物质的工艺,对影响多酚得率的因素进行了单因素试验,通过正交试验确定最佳工艺条件为:乙醇体积分数为65%,浸提温度为75℃,料液比为1∶30,浸提时间为5h,此条件下多酚类物质的提取率为5.66mg/g。 The extraction conditions of polyphenol from the peanut shell by infuse extraction method were studied. Suitable conditions were determined based on the single factor tests and L9（34） orthogonal design. They were as follows： ethanol density 65%, extraction time 5 h, ratio of solid to liquid 1 ： 30, extraction temperature 75 ℃, the extracting ratio of polyphenol could approach to 10.32 mg/g.
