摘 要:海蒿子(SargassumconfusumAgardh)经热水抽提、乙醇沉淀、DEAE-SephadexA-25柱层析分离,得到多糖DEI、DEII,糖质量分数分别为52.40%,38.80%。经酸降解、薄层层析、气相色谱-质谱分析,证明其单糖组成均为岩藻糖、木糖、半乳糖、果糖、甘露糖、葡萄糖。其中岩藻糖质量分数最高(DEI:39.3%;DEII:35.2%)。The characteristics of the polysaccharide DEI and polysaccharide DEll isolated from Sargassum pallidium through water extraction, ethanol precipitation and DEAE-Sephadex A-25 column chromatography sequentially were analyzed by TLC, gel electrophoresis and GC-MS. It was found that these polysaccharides were composed of fucose, xylose, galactose, fructose, mannose and glucose, among them fucose being the primary component (39.3% in DEI and 35.2% in DEII).
