Ulva fasciata belonging to the family Ulvaceae, commonly known as ‘sea lettuce’, is an abundantly growing green seaweed in coastal seashore of South China. Three different molecular weight sulfated polysaccharides (UFP1, UFP2 and UFP3) were extracted and separated from U. fasciata by hot water extraction and ultrafiltration. The three native UFP fractions had partial desulfurization by solvolytic desulfation respectively and the effect of sulfate content on the exhibition of the antioxidant and anti-tumor capacities had been evaluated and compared. The results showed that each native polysaccharide (UFP1, UFP2, UFP3) with high sulfate content exhibited better antioxidant activities compared with the partial desulfated polysaccharides (DS-UFP1, DS-UFP2, DS-UFP3). Specifically, UFP2 with relatively high sulfate content, molecular weight and uronic acid content had consistently excellent antioxidant performances. However, UFP2 demonstrated the minimal inhibitory effects on growth of DLD intestinal cancer cells. Instead, DS-UFP3 with the lowest sulfate content but highest uronic acid content and molecular weight exhibited the best antitumor activity.
