Key points

  • The intracellular polysaccharide (IPS) from Flammulina velutipes SF-08 mycelia was isolated and degraded by enzyme and acid
  • IPS and its derivative were purified by DEAE-52 cellulose chromatography, and five fractions were obtained
  • The structural features and antioxidant activities in vitro of the isolated fractions were evaluated
  • On the basis of chemical composition and antioxidant ability analyses, rhamnose as the main monosaccharide might contribute to the strongest antioxidant capacity
  • The in vivo results showed that IPS significantly enhanced the activities of anti-aging enzymes, such as superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activity, and reduced the content of lipid peroxidantion (LPO)
  • These results suggested that IPS should be a potent natural polymer and can be developed to be novel functional food
