Research Advances on Structural Characteristics and Bioactivity of Tremella fuciformis Polysaccharides

The chemical structures of the polysaccharides from fruit body, spore, and submerged culture of T. fuciformis are similar. T. fuciformis polysaccharides mainly consist of heteropolysaccharides with α-(1→3)-linked D-mannan as the backbone chain, exhibiting diverse activities such as immunomodulation, antitumor, antioxidation, and antiaging. The present paper reviews the structural characteristics, various activities and structure -activity correlation of T. fuciformis polysaccharides.
