玉足海参多糖的分离及理化性质研究

Studies on Polysaccharides from Holothltria leucospilota

从玉足海参干燥体壁中分离到一种粉末物质,经红外光谱、紫外光谱、纸层析以及理化分析,表明为一硫酸粘多糖,其组成中氨基半乳糖:葡萄糖醛酸:岩藻糖:硫酸基的分子比值为1:0.96:0.78:1.98。本文还报道了该多糖的比旋度、特性粘度和分子量。

A powder was obtained from the dried body of Holothuria leucosilota (Brandt). According to IR and UV spectra?paper chromatography and the physical and chemical data, it is showed a sulfated mucopoly-saccharide consisted of galactosamine, glucouronic acid, fucose and sulfate with the molar ratio of 1:0.96:0.78:1.98 respectively. The specific rotation, intrinsic viscosity and molecular weight of this polysaccharide were all presented.
