Abstract: Crude and purified polysaccharides from Equisetum ramosissimum Desf. were evaluated for antioxidant properties and compared with VC. Both crude and purified polysaccharides had scavenging activity against ?OH, O2 -? and NO2 - in a concentration-dependent manner. The crude polysaccharides showed stronger free radical scavenging activity and potent inhibitory effect against lipid oxidation, but both polysaccharide samples had weaker antioxidant effect than VC.

Key words: Equisetum ramosissimum Desf., polysaccharide, antioxidant activity
