ABSTRACT
Due to wonderful taste, rich nutrition and biological functions, many marine green algae in the genus Caulerpa have been recently developed as candidates for green caviar. A novel water-soluble sulfated xylogalactomannan CO-0-1 was obtained from the green algae Caulerpa okamurae. CO-0-1 was mainly composed of mannose (Man), galactose (Gal), and xylose (Xyl) at the ratio of 4.44.01.4 with the molecular weight at 470 kDa and the sulfate content at 12.78 %. The sulfated xylogalactomannan had Man at the backbone with â4)-ß-D-Manp-(1â and â2)-ß-D-Manp-(1â as the main chain and branches at O-3 position. The side chains contained â3)-ß-D-Galp-(1â and minor â2)-ß-D-Xylp(1â. The sulfate groups only distributed at the side chains and at O-6 position of â3)-ß-D-Galp-(1â and O-4 position of (1â2)-ß-D-Xylp. The anticoagulant activity indicated that CO-0-1 displayed intrinsic anticoagulant and specific anti-thrombin activities. The investigation expanded the utilization and development scene and scope of the green algae Caulerpa okamurae.
