唇形科植物提取物对单胃动物的抗氧化作用及其机制

动物在患病、应激或特殊生理条件下，机体内会大量产生自由基，自由基与机体内的脂质、ＤＮＡ等产生反应，可对动物造成氧化损伤。唇形科植物提取物中的抗氧化物主要活性成分是酚类化合物，它和抗坏血酸及类胡萝卜素能够阻止自由基引发的氧化伤害。本文阐述了唇形科植物提取物对猪、鸡体外和体内抗氧化作用的实例与抗氧化功能，分析了其抗氧化作用机制。

Antioxidation and Machnism of Lamiaceae species Extract in Monogastric Animals

Under the diseases,oxidative stress and special physiological conditions,large numbers of free radicals emerge,which leads to lipid peroxidation,enzyme inactivation and oxidative NDA damage.Some of the beneficial effects of Lamiaceae species extract are attributed to the presence of phenolic compounds.Phenolic compounds,ascorbic acid and carotenoid as antioxidants are considered to play an important role in scavenging the free radicals and prevention or delay of the oxidative damage caused by free radicals.This paper summarized the in vitro and in vivo studies of antioxidant activities and modes of action/functions of Lamiaceae species extracts in monogastric animals,and the potential antioxidant mechanism was also disscused.
