Abstract

The body of tremella were decocted with water, and hydrolyzed with 0.1 mol/L hydrochloric acid for different times, giving tremella polysaccharides with six molecular mass values. The structures of all the tremella polysaccharides had non-reducing terminals of β-D-pyranglucuronide, the backbone was composed of (1 → 3)-linked β-D-manno-pyranoside, and the side chain composed of (1 → 6)-linked β-D-xylopyranoside was attached to the C(2) of the backbone mannopyranoside. Immunomodulatory effect studies indicated that tremella polysaccharides increased the counts of leukocytes in the peripheral blood which were significantly lowered by cyclophosphamide, and the lower the molecular mass of the tremella polysaccharide, the better this effect was.
