Research on the Purification and Anti-Oxidize Activity of Tremella Polysaccharide

Abstract

Abstract: The tremella polysaccharide was purified by DEAE-Cellulose and Sephadex G-200, and then obtained a pure homopolysaccharide TPP2. The ability of the tremella polysaccharide to scavenge the hydroxyl free radical in the test was carefully observed, and the outside anti-oxidize activity of acidity polysaccharide was researched. It was proven in the test that TPP2 showed active ability in scavenging the hydroxyl free radical, the sample thickness was 66.5μg/ml in 50% scavenging rate.TPP2 restrains obviously the peroxide of lard.

Key words: tremella polysaccharide, purification, scavenging, anti-oxidize
