Antihyperlipidemic activity of high sulfate content derivative of polysaccharide extracted from Ulva pertusa (Chlorophyta)

In this study, high sulfate content ulvan (HU) was prepared with sulfur trioxide/N,N-dimethylformamide (SO3–DMF) in formamide, and the antihyperlipidemic activity of ulvan and HU in mice was determined. Obvious differences in antihyperlipidemic activity between natural ulvan and HU were observed, moreover, the antihyperlipidemic activity of HU-fed 250 mg/kg was the strongest, compared to natural ulvan fed group, triglyceride (TG) and low density...
