A water-insoluble polysaccharide (WIP) was isolated from the fruiting bodies of Hericium erinaceus HE01 by an alkaline solution with the yield of 5%. Structural and compositional analyses by total acid hydrolysis, methylation analysis, FT-IR, FT-Raman, and ¹H NMR spectroscopy as well as other instrumental techniques showed predominantly glucose linked by α-glycosidic bonds and small amounts of mannose, xylose, rhamnose, galactose, and ribose. The methylation analysis showed that (1→3)-linked Glcp is the major constituent (70.8%) of the polymer, while the 3,4 substituted d-Glcp represents the main branching residue of the glucan. The presence of (1→3)-α-d-glucan in the hyphae of H. erinaceus was additionally confirmed by the use of specific fluorophore-labeled antibodies.
