RESUMO
Sulfated polysaccharides were extracted with acetone from brown algae Padina gymnospora. The fraction precipitated with 1.5 volumes of acetone (F1.5) purified in Sephadex G-75 was characterized by infrared and nuclear magnetic resonance of 13C and ¹H, through which the presence of sulfate groups on the C4 of α-L-fucose could be observed. This polysaccharide showed that an MW of 25,000 Da was effective in reducing leukocyte influx into the peritoneal cavity in mice at 10 mg/kg and 25 mg/kg body weight, causing a decrease of 60 and 39 percent, respectively. In the present study, it was observed that this fucan has anti-inflammatory properties but no cytotoxic action, indicating its potential use in the pharmaceutical industry.
