姬松茸多糖提取方法初探

A Preliminary Study on the Extraction Methods of Polysaccharides from Agaricus blazei Murrill

姬松茸子实体多糖提取的最佳条件是加水量 1∶30 ,沸水浴 4h ,乙醇沉淀浓度 80 %。

The extracting conditions of polysaccharides from Agaricus blazei Murrill fruitbodies were studied in this paper. Through orthogonal test, we found that the best conditions for extracting A.blazei polysaccharides were as follows: adding water at a ratio of 1:30 (dry A.blazei fruitbody wt.:water wt.), extracting for 4h at 100℃ and precipitating with 80% ethanol. And the compositions and contents of amino acids in the polysaccharides extracted from A.blazei fruitbodies and precipitated with different concentrations of ethanol were analyzed too.
