鸢尾苷抗氧化活性的研究

Investigation of Antioxidant Capacity of Tectoridin

在成功从中草药射干中提取纯化得到鸢尾苷的基础上,应用灵敏、简单易行有效的方法考察鸢尾苷的抗氧化能力。选择氧自由基清除、羟基自由基清除、二苯代苦味肼基自由基清除、烷基自由基清除和抗油脂氧化作用等实验体系进行抗氧化活性的试验。结果显示纯化得到的鸢尾苷的抗氧化作用比维生素C稍强,但比2,6-二叔丁基对甲酚稍弱,表明其具有较显著的抗氧化作用。

Tectoridin was successfully isolated from Rhizoma Belamcandae. The antioxidant capacity of isolated tectoridin was examined via some sensitive,simple,effective methods including oxygen radical scavenging,hydroxyl radical scavenging,diphenyl bitterness hydrazine radical scavenging,alkyl radical scavenging and anti-lipid oxidation assays. The results showed that the antioxidant effects of tectoridins is weaker than 2,6-ditertiary butyl-p-cresol,but is stronger than vitamin C. It is suggested that the antioxidant capacity of Tectoridin is more significant.
