| Popis: | A novel water-soluble heteropolysaccharide FVP60-B was extracted from the fruiting bodies of Flammulina velutipes with boiling water and purified by Sephacryl S-300 and S-400, which molecular weight was estimated to be 1.3 × 10 4 Da by HPLC. It is composed of l -fucose, d -mannose, d -glucose and d -galactose in a ratio of 1.16:0.82:1.00:3.08. Sugar analysis, methylation analysis together with 1 H, 13 C and 2D NMR spectroscopy disclosed that FVP60-B is consisted of a α-(1 → 6)- d -galactopyranan backbone with a terminal fucosyl, terminal glucosyl and α-(1 → 6)- d -mannopyranan units on O -2 of 2,6- O -substituted- d -galactosyl units. |
