植物提取物抗氧化成分及机理研究进展

Research Advances in Antioxidant Composition of Botanical Extracts and Their Action Mechanisms

自由基对机体的氧化损伤可导致许多疾病的发生,自然界中很多物质具有抗自由基氧化作用。植物是人体外源性抗氧化物质的最重要来源,本文简述了植物提取物多酚、维生素、生物碱、皂苷、多糖、活性肽等抗氧化成分及其抗氧化机理的研究进展,为植物提取物的抗氧化研究开发提供参考。

Oxidative damages to organisms caused by free radical might lead to the occurrence of many diseases,while many natural substances have the ability to scavenge free radicals.Plants are the most important source of human body exogenous antioxidants.This article summarizes previously reported studies on antioxidant composition of botanical extracts mainly consisting of polyphenols,vitamins,alkaloids,saponins,polysaccharides,bioactive peptides plants,and so on and their acition mechanisms.
