초록

A hot-water extract from fruit body of Auricularia auricula was purified by ethanol precipitation and subsequent dialysis. The polysaccharide showed a typical IR spectrum similar to $\beta$-glucan and was composed of glucose and mannose in a molar ratio of 16.8:83.2 indicating that it is a glucomannan. A glucomannan-like polysaccharide was also identified from Tremella fuciformis. Both of the polysaccahrides showed the presence of acetyl groups and presented colorimetric responses for $\beta$-1,4-glucomannan indicating the acetylated $\beta$-glucomannan similar to the typical polysaccharide found in Aloes.
