Alkali-soluble polysaccharides have been extracted from Laetiporus Sulphureus (Bull.: Fr.) Murr fruit bodies with a yield of 42.7%. The structure of the dominant polymer (16.05% of fruit bodies’ mass), named latiglucan I, has been determined. It is linear β-1,3-glucan (molecular weight 1.8 × 105 Da, [α]D-17°).
