摘要: 目的:研究三叉苦不同部位水提取物的抗氧化作用及其规律,为食品或药物抗氧化剂的筛选和应用提供理论依据。方法:应用化学发光法检测三叉苦的各部位水提取物对邻苯三酚 -CTMAB 体系产生的超氧阴离子自由基(O2·)、邻菲罗啉 - 抗坏血酸体系产生的羟自由基(·OH)及过氧化氢(H2O2)的清除作用。结果:三叉苦水提取物具有明显的清除超氧阴离子自由基、羟自由基和过氧化氢的作用,清除率与浓度之间存在着明显的量效关系。结论:证明了三叉苦各部位的水提取物均是一种有效的抗氧化剂。

Abstract: Objective: To study the antioxidative effects and its regularity of Evodia lepta (collected in China, Hainan). Method: Scavenging effects of Evodia lepta on hydroxyl radical (·OH) produced from O-phenathroline-ascorbic acid system, super oxide anion radical(O2·) produced from pyrogallol-CTMAB system and hydrogen peroxide(H2O2) was studied by chemilu- minescence assay. Result: The water extract of Evodia lepta has a significant effect on hydroxyl radical, super oxide anion radical and hydrogen peroxide. Conclusion: The water extract of Evodia lepta is an efficiency antioxidant.
