摘要
研究万寿菊黄色素的体外抗氧化特性,测定万寿菊黄色素对抗油脂氧化能力、清除超氧阴离子和羟基自由基的能力。结果表明:万寿菊黄色素在对抗油脂氧化、清除超阴离子自由基和清除羟基自由基活性随着浓度的增大而增大,这种影响都是显著的(单因素方差分析,P<0.05)。万寿菊黄色素对超氧阴离子自由基的清除能力(IC50=8mg/L)强于对羟基自由基的清除能力(IC50=97mg/L),相差10倍以上。
The antioxidant properties of yellow pigment from Marigold by supercritical CO2 extraction were evaluated by determination of the anti-lipid oxidation activity and scavenge capacities on superoxide anion radicals and hydroxyl free radicals. The results indicated that the anti-lipid oxidation activity and scavenge capacities on superoxide anion radicals and hydroxyl free radicals were all in correlated with the contents of yellow pigment of Marigold, which was significantly different （one-way ANOVA, P〈0.05）. The scavenge capacity on superoxide anion radicals （IC~=8 mg/L） was more than 10 times that on hydroxyl free radicals （IC50= 97 mg/L）.
