摘要
用化学发光法研究红曲色素中不同成分对羟自由基的消除作用。结果表明,红曲色素红、橙、黄三类色素中红色素抗氧化性最强,其次为黄色素,橙色素抗氧化性最差;红色素中分子量为365的抗氧化性最强,其次为分子量为391 的红色素,分子量为380和900的红色素抗氧化性最差。
The effects of monascus pigments on elimination of hydroxide free radical were studied by chemiluminescence method. The results showed that the antioxygenic ability of monascus pigments from high to low in sequence were red, yellow and orange pigment.For red pigment, molecular weight of 365 got the highest antioxygenic ability, then molecular weight of 391, the last molecular weight of 380 and 900.
