| Abstract: | The scavenging effect of polysaccharide extracts of Ulva pertusa on O2^- and OH· , inhibiting lipid peroxidation effect and its antioxidant effect on grease were studied, the results showed that polysaccharide extracts of Ulva pertusa had scavenging effect on O2^- and OH·, and the effect improved with the increase of polysaccharide concentration, markedly increased scavenging effect in a dose dependent manner. The conclusion was that polysaccharides from Ulva pertusa had certain antioxidant activity, and the added concentration was positively correlated with antioxidant activity. |
