摘    要:从清除羟基自由基和超氧阴离子自由基、抗脂质过氧化以及还原能力等方面对板栗壳棕色素的抗活性氧自由基进行了试验研究和评价,结果表明:板栗壳棕色素对 Fenton 反应产生的羟基自由基和光照核黄素产生的超氧阴离子自由基均具有较强清除作用.对脂质过氧化过程中产生的脂自由基和脂过氧化自由基有明显的抑制作用.且在试验浓度范围内,其最大清除率或抑制率分别可达到 83.0%、82.1%和 88.5%.表明板栗壳棕色素是一种优良的天然抗氧化剂和自由基清除剂.

关 键 词:板栗壳棕色素  羟基自由基  超氧阴离子自由基  还原能力  脂质过氧化  板栗壳棕色素  活性氧自由基  清除作用  shell  pigment  brown  oxygen  radicals  active  scavenging  清除剂  天然抗氧化剂  抑制率  清除率  浓度范围  抑制作用  氧化自由基  氧化过程  核黄素  光照  反应

Abstract:The paper studied the scavenging active oxygen radicals of brown pigment from chestnut shell.The results showed that the brown pigment had scavenging effects on hydroxyl radical,superoxide anion radical and aliphatic radicals on lipid-peroxidation.In the range of test concentration,the maximum scavenging or inhibition rate of the brown pigment to hydroxyl radical generated by Fenton reaction,superoxide anion radical generated by illuminating riboflavin system and linoleic acid auto-oxidation was 83.0%,82.1% and 88.5% respectively.The results suggested that the brown pigment from chestnut shell was an excellent natural antioxidant and free radicals scavenger.
Keywords:chestnut shell brown pigment  hydroxyl radical  superoxide anion radical  reducing capacity  lipid peroxidation
