Abstract:
Objective The polysaccharides sulfate were extracted from three kinds of algae in-cluding porphyra tenera , Laminaria ja ponica and Sargassum fusi forme ( Harv. )Setch . in order to screen antioxidant with exploiting potential. Methods Using the assay system of DP-PH,the antioxidative activities of various extracts were studied. Results Three kinds of algae polysaccharides sulfate had different antioxidative activities. Moreover, polysaccharide extracted with different solvents had different intensities of antioxidative activity. Conclusion Polysacchride sulfate extracted with water has stronger antioxidative activity than that with others.keywolds antioxidation; porphyra tenera kjellm. ; Laminaria japonica; Sargassum fusi -forme ( Harv. )Setch.Studies on the extraction of polysaccharides sulfate from three algae and their scavenging activity on free radicalsHAN Hua,ZHOU Hai Yan,LIU Cheng-Chu,WANG Chun-bo(1.Bromatology Institute of Shanhai Aquatic University , Shanghai 200090, China; 2.
