Antioxidant properties of structurally different sulfated polysaccharides (carrageenans) were studied in vitro and ex vivo. Ferric reducing antioxidant activity of carrageenans and their inhibitory effects on hydroxyl radicals and superoxide anion radicals were demonstrated in vitro. Activity of carrageenans depends on the polysaccharide structure. Carrageenans stimulate catalytic activity of SOD from donor erythrocyte.
研究了结构不同的硫酸化多糖（角叉菜胶）在体外和体内的抗氧化特性。在体外证明了角叉菜胶的铁还原抗氧化活性及其对羟基自由基和超氧阴离子自由基的抑制作用。角叉菜胶的活性取决于多糖结构。角叉菜胶可刺激供体红细胞中超氧化物歧化酶的催化活性。
