摘　　要：本文就海藻硫酸多糖(SPS)的结构特征、制备,抗氧化机制及影响因素进行了较为详细的阐述。众多研究表明,SPS是从海藻中提取的一类生物活性多糖,是多糖分子链中单糖分子的部分羟基被硫酸根取代而形成的;它能有效地清除自由基,还能与金属离子鳌合,抑制脂质过氧化作用,具有显著抗氧化活性;制备粗多糖主要采用水提醇沉法,用离子交换、凝胶渗透和亲和层析法进行纯化;影响SPS抗氧化活性的因素主要有硫酸多糖的来源、多酚含量、相对分子质量大小以及硫酸基的含量与位置等。In this paper, the structural characteristics, preparation, antioxidant mechanism and influence factors of Sulphated polysaccharides （SPS） were described in detail. Many researches indicated that, SPS was a kind of biological activity polysac- charide, extracted from seaweed, which formed by the displacement of some hydroxyl groups monosaccharide molecules with sulphate acid groups in polysaccharide molecules chains; SiX3 could effectively clear free radical, chelate metallic ire and had significant antioxidant activity; crude polysaccharide was extracted by ethanol, purified using ion - exchange chromatography, gelflltration techniques and affinity chromatography; the influence factors of SPS antioxidant activity were the source of SIX3, polyphenol content, relative molecular mass and sulphate acid groups content and position.
