The chemical properties of Lentinan were studied by chromatography analysis and spectroscopic analysis. Gelatin chromatography was used. Spectrophotometry, turbidometric titration and viscosity measurement were used to study its polymer properties. .

There is a characteristic peak at 0 n m, which is completely hydrolyzed to D-glucose, D-mannose, D-galactose, and L-fucose. Silica gel column separation is divided into two fractions and their molecular weights are respectively 1. 0 × 10 4 , 8 . 9 ×104, Θ T = 22 . 2 ±0. 02 °C, Θ Solvent: V water: V acetone = 80 . 45:19. 55.
