Citation abstract

A polysaccharide (FVSP) was isolated from the base of Flammuliana Velutipes stipe, and FVSP was further purified by DEAE-cellulose-52 chromatography and Sephadex G-100 size-exclusion chromatography to obtain three fractions named FVSP-1, FVSP-2 and FVSP-3. Then their activation of macrophage cell RAW 264.7 and anti-proliferative effects to the murine melanoma B16F10 and fibroblasts L929 cells were evaluated by using the cell model experiments. The results indicated that the polysaccharide fractions could increase the proliferation and phagocytic activity of macrophage significantly and play an inhibited effect on the cancer cells. Moreover, the anti-proliferative activities of FVSPs increased with the participation of the antitumor factors induced from macrophage by polysaccharides fractions. Taken together, these results indicated that three polysaccharides fractions from the base of F. Velutipes stipe may be useful as potent antitumor agents for the prevention of tumorigenesis.
