摘要: 本研究用邻二氮菲法、NBT法和Cu2+诱导低密度脂蛋白(LDL)氧化法分别对燕麦β-葡聚糖和酚类提取物的·OH清除能力、O2·清除能力、LDL氧化抑制能力进行评价。结果显示,燕麦β-葡聚糖没有抗氧化能力,而燕麦酚类成分却具有较强的抗氧化能力和潜在的抗动脉粥样硬化能力。

Abstract: In this study, the hydroxyl radical scavenging capacity, super oxygen-anion free radicals scavenging capacity and LDL oxidation inhibition ability of oat β-glucan extract and phenolics extract were studied. Results showed that Oat β-glucan has no antioxidant activity. However, oat phenolics has significant antioxidant activity and antiatherogenic potential.
