Abstract: Plant antioxidants and their related active compounds can be divided into the following categories:flavonoids,plant polyphenols,phenolic acids,vitamins,polysaccharides,enzymes,proteins and amino acids.Antioxidants may exert their effects on biological systems through different mechanisms including electron donation,metal ion chelation,synergistic effect of antioxidants or by genes expression regulation.The applications of antioxidants as additives are widespread in the fields of food,beverages,medicines and cosmetics.It is proposed that the following studies should be carried out more intensively:selection of raw materials,innovation of extraction and separation,mechanism of synergistic effects of antioxidants,relationship between compound structures and antioxidant activities.

Key words: plant antioxidants, flavonoids, phenolic acids, plant polyphenols, active polysaccharides
