摘　　要：对花生壳中黄酮物质的提取工艺进行了优化研究,并对提取物的抗氧化性进行了初步研究。用单因素试验分别对提取溶剂乙醇体积分数、料液比、提取时间及提取温度进行了研究。在此基础上,通过正交试验确定上述4个因素的最佳组合。优化后花生壳中黄酮的最大提取率为92.32%,花生壳中黄酮类化合物的适宜提取条件为乙醇体积分数60%、料液比1∶30、提取时间150min、提取温度60℃。花生壳中黄酮类化合物对猪油有明显的抗氧化作用,当添加量为0.2%时抗氧化效果与0.2%BHT接近。To optimize extracting parameters of flavones from peanut hull was studied. Based on the single factors test of ethanol concentration, material and solvent ratio,extracting time and extracting temperature, orthogonal test was performed and the best combination was confirmed.With the optimized technology,the maximal extracting rate of flavonas from peanut hull was 92.32% .The optimal techniques obtained were 60% ethanol extracting at 60 ℃ with material and solvent ratio 1：30 for 150 rain. The results showed that the dosage of tlavones was indirect proportion to the antioxidation. When the concerttration of flavones was 0.2% ,the antioxidative effect was as good as 0.2% BHT.
