摘要: 利用醇法提取了黑米等四种粮豆作物中的花色苷。通过花色苷对DPPH自由基的抑制作用和对羟自由基的清除作用,比较了花色苷的抗氧化性能的活性,考察了花色苷的总酚含量与抗氧化性能的关系。结果表明:四种花色苷对DPPH自由基的抑制率为红豆>黑米>芸豆>黑豆,对羟基自由基的清除率与DPPH结果相同,总酚含量越高抗氧化活性越强。

关键词: 花色苷, DPPH, 羟自由基, 抗氧化性

Abstract: The anthocyanins were extracted from four kinds of plants with ethanol.The antioxidant of anthocyanins was studied by the inhibition ability on DPPH and scavenging ability on hydroxyl radical.The relationship between the antioxi-dant and the phenol content was discussed.The results showed that the inhibition ability on DPPH:red bean>black rice> kidney bean>black bean,the scavenging ability on hydroxyl radical is as same as DPPH,and the higher phenol has the strongera ntioxidant.

Key words: anthocyanin, DPPH, hydroxyl radical, antioxidant capicity
