Abstract: The research on the extracting technology of Auricularia polysaccharide was studied in this paper. The results showedthat the extracting rate of polysaccharide was 4.38%.The extracting rate could be increased by enzymatic technology. The besttechnological conditions for the extraction were as follows: the ratio of material and water was 1:60 with a temperature of 80℃and extracting time 2.5h and the amount of Proteinase and cellulase used was 650 IU/g and 375 IU/g respectively with a reactingtime of 1.5h at the temperature of 43℃. The optimum pH of the two respectived enzymes was 7.4 and 5.3.

Key words: Auricularia, polysaccharide, proteinase, cellulase, extraction
