Abstract:

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.

Key words: free radical, botanical extract, antioxidant ingredient, mechanism
