Antioxidant and antihyperlipidemic activities of purified polysaccharides from Ulva pertusa

Several studies have reported that ulvan from the alga Ulva pertusa (Chlorophyta) exhibits substantial antioxidant and antihyperlipidemic activities; however, which group of heteropolysaccharides play roles in these activities remains unknown. To identify the components of ulvan that possess biological activity, we used a DEAE-Sepharose fast-flow column. Two purified polysaccharides (F1 and F2) were detected and their physicochemical properties,...
