SULFATED POLYSACCHARIDES FROM GREEN SEAWEED Codium Tomentosum FROM CANAKKALE STRAIT (TURKEY).

The polysaccharide extraction and structural characterization of Codium tomentosum from green algae were investigated in this project. After extraction using acetone and dichloromethane, it was purified with a phosphate buffer to obtain a highly purified Codium tomentosum polysaccharide (CTPS). The structure of CTPS was characterized by highperformance liquid chromatography (HPLC), ultraviolet-visible (UV), Fourier transforms infrared (FTIR), and nuclear magnetic resonance (1HNMR) spectrum. Additionally, the DPPH free scavenging activity of CTPS was also examined. Our results determined that purified extract includes L-Arabinose, L-Rammnose, L-Fructose, L-Mannose, L-Galactose, and L-Fucose. Furthermore, it was found that CTPS has free radical scavenging activity. The results showed that the polysaccharide obtained from Codium tomentosum could be applied as a potential natural source.
