Abstract
Polysaccharide from Nostoc commum Vauch. was extracted by water extraction and ethanol precipitation. The content of polysaccharide was determined and its antioxidant activity was researched through reducing power, •OH radical scavenging, ABTS+• radical scavenging and anti-lipid peroxidation. The results showed that the content of polysaccharide from Nostoc commum Vauch. could reach to approximately 25.3%; the polysaccharide had a concentration-dependent antioxidant effect; the polysaccharide could significantly decreased •OH radical, its maximal scavenging rate was 98.8%; the polysaccharide also had some effect on ABTS+• free radical and lipid peroxidation, its maximal scavenging rate and peroxidation rate were respectively 58.3% and 37.2%.
