摘要：The aim of the present work was to explore the composition, molecular weight and monosaccharide composition of , Flammulina velutipes polysaccharides by DEAE Cellulose-52, High Performance Gel Filtration Chromatography (HPGFC) and HPLC with PMP derivative with the FVP isolated and purified from Flammulina velutipes . The results showed that Flammulina velutipes polysaccharides were composed of three kinds of polysaccharides; the molecular weight of FVP was composed of 4191338, 372779, 19002; the molecular weight of 372779, 19002, one of the biggest average molecular weight polysaccharides is neutral polysaccharide, the rest of the two kinds of polysaccharide composition of less average molecular weight is acidic polysaccharides and the proportion of two kind of acidic polysaccharides significantly greater than neutral polysaccharide, 44.31 and 37.76% respectively, only 17.93% of neutral polysaccharide. FVP was composed of Glc, Man, Gal, Xyl, Fuc; the highest content of Glc, followed by Gal and Man, Xyl and Fuc content is relatively low. The molar ratio was relatively 13.05:2.75:3.16:1.48:1.00. In conclusion, FVP contained the more Glc, the less Fuc and a small amount of galacturonic acid and glucuronic acid, which showed FVP may contain acidic polysaccharides.
