    abstract = {In this study, the <I>ex vivo</I> anti-oxidation activity of polysaccharide extracted from the red seaweed <I>Porphyra yezoensis</I> was studied. The scavenging efficiencies for free radical O<SUP>2</SUP> , •OH and •DPPH, the inhibitory effects on mice erythrocytes hemolysis induced by H<SUB>2</SUB>O<SUB>2</SUB> as well as on the lipid peroxidation in mice liver homogenate, were systematically measured and analyzed. Results suggested that Porphyra polysaccharide, in the experimental concentration range, possessed anti-oxidation activity. The scavenging efficiency for O<SUP>2</SUP>  was found to be remarkably high and the maximum scavenging rate was 82.77%. The Scavenging efficiency for •OH was even higher than O<SUP>2</SUP>  with a maximum removing rate of 85.63% and the scavenging for •DPPH was 13.97%. The inhibitory effects on mice erythrocytes hemolysis and MDA formation in mice liver were significant and the maximum inhibition rates were 82.90 and 58.48%, respectively. The combined data indicated that the polysaccharide extracted from Porphyra had strong anti-oxidation activity.}
