This study was aimed to evaluate the multifunctional mechanism of quercetin as a antioxidative ingredient derived from plant foods. Rodent experiments demonstrated that dietary quercetin protects the intestinal mucosa of digestive tract, blood vessel, central nervous system and muscle tissue from oxidative stress by promoting the antioxidant enzyme expression as well asdirect ROS-scavenging and suppression of oxidant enzymes. It is implied that de-conjugation reaction by macrophage participates in these multifunction of dietary quercetin.

本研究旨在探讨从植物性食品中提取的抗氧化剂--栎皮素的多功能作用机制。啮齿动物实验表明，饮食中的槲皮素通过促进抗氧化酶的表达以及直接清除和抑制氧化物酶来保护肠道粘膜、血管、中枢神经系统和肌肉组织免受氧化应激的伤害。提示巨噬细胞的解偶联反应参与了饲料中槲皮素的这些多功能。
