Abstract:

Tetrasporic Pterocladia capillacea was sequentially extracted with water at room temperature, 50°, 70°and 90°. The polysaccharides obtained by extraction at 90°were fractionated by ion-exchange chromatography on DEAE Sephadex A-50 (Cl-), eluting with water and solutions of increasing sodium chloride concentration: seven fractions were separated. The two major fractions, one eluted with water and the other with 0.1 M NaCl, comprised 66.9% of that recovered and were mainly agarose. Structural analysis of the fraction eluted with 0.7 M NaCl is consistent with a backbone formed mainly by alternating 3-linked β-D-galactose and 4-linked α-L-galactose residues, highly substituted with sulphate and having single stubs of xylose and galactose.
