In this study, purification of polysaccharide ulvan by anion exchange chromatography was prepared, and the major polysaccharide fraction (FU) was collected at 1.0 M NaCl elute by anion exchange chromatography, then high sulfate content purified ulvan (HFU) was prepared with sulfur trioxide/N,N-dimethylformamide (SO3-DMF) in formamide. The antioxidant activity and the antihyperlipidemic activity of HFU in mice were determined. The results showed that treatment with HFU could improve the antioxidant and antihyperlipidemic activity. Compared with the hyperlipidemic group, the antihyperlipidemic activity of HFU (125 mg/kg) was the strongest, TC concentrations were significantly decreased by 26.7% (P < .01), significantly reduced LDL-C (32.6%, P < .01), significantly increased HDL-C (19.6%, P < .01), and HFU-treated group (250 mg/kg) exhibited optimal effects on TG (29.0%, P < .01); the HFU groups at the doses of 125 mg/kg could significantly decrease the MDA (29.9%, P < .01); the HFU groups at the doses of 500 mg/kg could increase the activities of GSH-Px obviously (19.9%, P < .01).
