摘    要:目的:对昆布多糖进行硫酸酯化,并对产物的纯度与结构进行分析,为研究其生物活性奠定物质基础.方法:利用氯磺酸-吡啶法对昆布多糖进行硫酸酯化,并使用HPLC-ELSD法测定反应产物的纯度与分子量;采用硫酸钡比浊法测定昆布多糖硫酸酯中SO2-4的含量,并利用波谱法研究其结构.结果:昆布多糖硫酸酯的纯度为96%,其分子量为16315,SO2-4含量为41.30%;紫外、红外光谱分析结果均显示硫酸酯化多糖的光谱特征,13C-NMR谱显示多糖的2位羟基为SO2-4的主要取代位置.结论:利用氯磺酸-吡啶法对昆布多糖进行硫酸酯化,该方法所得产物的纯度和酯化率高.

关 键 词:昆布多糖  硫酸酯化  昆布多糖硫酸酯  结构分析
