ABSTRACT
Introduction: Haliptilon subulatum is a seaweed from the Indian Ocean widely distributed along the north coasts of Madagascar. Although rich in polysaccharide like other algae belonging to the same families (Rhodophyceae), it is not exploited for the production of phycocolloids. Objectives: The objective of this work is to extract, purify and structurally analyze the polysaccharide from this species and then to test their biological properties. Methods: Our work therefore consisted of defining the conditions for extracting matrix polysaccharides from this alga, identifying its structure, characterizing its physicochemical and antioxidant properties, Results: The Haliptilon subulatum contains polysaccharide with a yield of 10 % and a molar mass of 213,500 g / mol (Ip 1.6) was mainly composed sulfate groups in position 4 of certain monosaccharides and a 3,6-anhydrogalactose bridge on the polysaccharide chains. This polysaccharide consists mainly of galactose (88.4%) and sulfate (13.5%). The polysaccharide and oligosaccharide fractions showed antioxidant properties. Conclusions: The polysaccharide of Haliptilon subulatum is of the galactan type sulphated in position 4 which is close to k-carrageenan.
