蛹虫草胞外多糖的提取和纯化

Isolation and purification of exopolysaccharide in Cordyceps militaris

对蛹虫草液体深层发酵液的胞外多糖提取进行研究 ,确定了提取的工艺条件 ,并对所提取的粗多糖进行分子筛分 ,对主要多糖组分的糖成分进行测定。其结果为 :蛹虫草液体深层发酵液的胞外粗多糖的提取率为 10 .0g/L ;其粗多糖主要由 4种蛹虫草多糖组成 ;而第 4个组分占总粗多糖的 32 .14% ,由葡萄糖构成。

Isolation of exopolysaccharide from submerged fermented liquid of Cordyceps militars has been studied. The exopolysaccharide is isolated and purified through Sephadex G 100 column. The major compositions of polysaccharide are identified. The isolation rate of exopolysaccharide is 10.0?g/L. The gross polysaccharide is primarily composed of four polysaccharides, and the fourth component, accounted for 32.14% , is glucose.
