The purpose of this study was to assess the relative antioxidant activities of a range of carotenes and xanthophylls through the extent of their abilities to scavenge the ABTS(.+) radical cation. The results show that the relative abilities of the carotenoids to scavenge the ABTS(.+) radical cation are influenced by the presence of functional groups with increasing polarities, such as carbonyl and hydroxyl groups, in the terminal rings, as well as by the number of conjugated double bonds.
本研究的目的是通过一系列类胡萝卜素和叶黄素清除ABTS(.+)自由基阳离子的能力范围,评估它们的相对抗氧化活性。结果表明,类胡萝卜素清除ABTS(.+)自由基阳离子的相对能力受末端环中极性不断增加的官能团(如羰基和羟基)的存在以及共轭双键数量的影响。
