摘　　要：用DPPH法,研究了不同溶剂提取桔皮中黄酮类化合物的氧化活性。结果表明,用75％乙醇提取的黄酮类化合物的抗氧化活性最佳。其它提取黄酮类化合物的抗氧化活性较高的溶剂依次是50％甲醇、75％甲醇和95％乙醇。这项研究为黄酮类化合物的提取及应用提供了科学依据。Antioxidant activity of flavonoid compounds from orange peel extracted with different solvents were investigated by DPPH( 1.1 - diphenyl - 2 - picrylhyzazyl). The result showed that antioxidant activity of flavonoid compounds extracted by using 75% alcohol is the best. Other solvents that extract flavonoid compound and make them have higher antioxidant activity are 50% methanol,75 %methanol and 95% alcohol.
