Various seaweed polysaccharides are getting great attention for intensive research due to their diverse biological activities, including effects on the immune system and cancer. Capsosiphon fulvescens, a green algae is widely distributed in the Southern coastal area of Korea. Crude polysaccharides were obtained from this seaweed collected at a coastal area of Wando, Korea, mainly by dilute acid extraction, ethanol precipitation and CaCl2 precipitation, with an yield of approximately 2.49% in mass. It was further purified by DEAE-cellulose column chromatography. The purified polysaccharide was examined for its immunostimulating activity on Raw 264.7 cells and shown to stimulate the production of TNF-α in a dose-dependent manner. The primary structure of this polysaccharide was analyzed by High Performance Anion Exchange Chromatography and Fourier Transform Infrared (FT-IR) spectrometry. From the HPAEC-PAD analysis, the monosaccharide composition of this purified polysaccharide was shown to be mannose(58%), rhamnose(33%), galactose(3.8%), xylose(3.3%), fucose(0.76%), and arabinose(0.67%). The IR spectrum showed a strong absorption band at 1256 cm-1, indicating the presence of sulfate esters. Absorption bands at 845 cm-1and 1060 cm-1 characteristic for galactose-4-sulfate and Sulfur trioxide, respectively, were also observed. From HPLC analysis molecular mass of this polysaccharide was determined to be approximately 385 kDa.
