摘要
采用双酶法提取螺旋藻多糖 ,脱蛋白效果接近100 %。通过DEAE—Sepharose和Sephadex -G50纯化粗多糖 ,得到2个多糖组分。经测定组分1的单糖组成为D—葡葡糖、D—木糖、D—半乳糖、葡萄糖醛酸 ;组分2的单糖组成为 :D—葡萄糖、D—甘露糖、L—鼠李糖、D—半乳糖、葡萄糖醛酸。
Two enzymes were used in this article for separation of polysaccharide from spirulina platensis ,the removing rate of protein was nearly 100%.Purified by DEAE-Sepharose and Sephadex-G50 column,two polysaccharide fractions were obtained.The composition of fraction l is D-glucose,D-xylose,D-galactose,glucuronic acid, fraction 2 is D-glucose,D-mannose,L-rhommose,D-galactose,glucuronic acid.
