A Sulfated Polysaccharide from the Green Alga <i>Caulerpa taxifolia</i>: Characteristics of Its Structure and Anti-Diabetic Activity.

ABSTRACT: Polysaccharides derived from green algae have garnered significant attention owing to their distinctive structural characteristics and biological activities. In particular, sulfated polysaccharides from these algae represent a promising frontier in the discovery of novel therapeutic agents. In this present study, a sulfated galactan from Caulerpa taxifolia, designated SGC, was obtained by dilute alkali extraction and chromatographic purification. On the basis of chemical and spectroscopic analyses, the backbone of SGC was constituted by a backbone of →3)-β-d-Galp-(1→ with sulfate substitution at the C-2 and a branch on C-6. The side chains contained →6)-β-d-Galp(2SO₄)-(1→, →6)-β-d-Galp(3OMe)-(1→ and →3)-β-d-Galp(4,6-Pyr)-(1→ units. SGC possesse
