摘　　要：对褐藻中岩藻聚糖的提取工艺进行优化,并对该多糖的糖类成分进行分析。该多糖由L(-)-岩藻糖、D-木糖、D-甘露糖、D-葡萄糖、D-半乳糖组成,各单糖含量为40.63%、2.75%、25.89%、22.10%、8.63%(质量分数)。并采用蛋氨酸光照法测定褐藻中岩藻聚糖对超氧离子的催化歧化作用。结果表明,岩藻聚糖对超氧离子有一定的抑制作用。The procedure of extracting fucoidan from kelp has been optimized in this paper,and it＇s chemical components have been analyzed subsequently.The monosaccharide composition of fucoidan was analyzed by GC,and this polysaccharide is made up of L（-）-Fucose、D-Xylose、D-Mannose、D-Glucose、D-Galactose,and their contents are 40.63 %,2.75 %,25.89 %,22.10 %,8.63 %（quality fraction）,respectively.The Dismutation to O2-free radical has also been investigated.The extracting fucoidan showed a distinct O2-·scavenging effect.
