Purification, Characterization and Antioxidant Activity of Green Seaweed Codium sp
2016
In the present study the Codium sp. polysaccharide was extracted and partially purified in DEAE cellulose. The polysaccharide was estimated for carbohydrate, sulfate content and uronic acid. The elemental analysis of polysaccharides was analyzed for carbon, hydrogen, nitrogen and sulfur. The antibacterial activity of polysaccharide showed maximum 19 mm of inhibition zone against Bacillus cereus and 12 mm of inhibition zone against Xanthomonas sp. Free radical scavenging activity of polysaccharide from Codium sp. was assayed for total antioxidant capacity, reducing power, hydrogen peroxide scavenging activity, DPPH, ABTS, hydroxyl scavenging assay, superoxide anion radical scavenging and nitric oxide. The green seaweed Codium sp. polysaccharide showed rich sources of antibacterial and antioxidant activity.
