Abstract: The Auricularia auricular polysaccharides were extracted by proteinase and celluloase, purified by DEAE- Cellulose 52 and Sepharose CL-4B chromatography.The molecular weight was determined by Sephadex G -100 chromatograph. The results showed that there are two main fractions in Auricularia auricular polysaccharides with the molecular weight of 31.7×104 and 18.3×104, respectively, which are non-starch polysaccharides, free of simple sugar, protein, nuclear acid and phenols.

Key words: Auricularia auricular, polysaccharides, chromatography, purify, molecular weight
