油茶总皂苷的抗氧化及清除自由基能力初步研究

Preliminary Study on the Capability of Antioxidation and Scavenging Free Radicals of Sasanquasaponins

本文对所提取的油茶总皂苷进行定性分析并测定其含量,研究了对由亚铁离子引发的卵磷脂脂质过氧化的抑制作用、清除Fenton反应生成的羟自由基的能力、清除超氧阴离子自由基的能力、对脱氧核糖氧化损伤的抑制作用,实验结果显示油茶总皂苷具有显著的抗氧化性和对脱氧核糖氧化损伤的抑制作用,对化学反应生成的的活性氧自由基具有显著的清除作用。

The experiment analyzed and measured the content of Sasanquasaponins and studied it＇ s capability to clear hydroxyl free radical （· OH） produced by Fenton reaction and to clear superoxide anion （O2^-·）. The results manifested that sasanqua have stronger antioxidant capability, inhibition capability of TBARS formation in Fe^2＋ induced liposome and strong inhibition capability of oxidation of 2＇-deoxyribose and could clear active oxygen radicals produced by the chemical reactions.
