摘要：

An alkali-soluble polysaccharide (Hunai polysaccharide, 1) from the fruit body of Pleurotus tuber-regium (Fr.) Sing was shown to be homogeneous by gel permeation chromatography and its molecular weight was similar to 4.3 x 10(5). Complete acid hydrolysis, periodate oxidation, Smith degradation, methylation, FT-IR and C-13 NMR analysis, complex formation with Congo Red, indicated that 1 has a beta-(1-->3)-linked D-glucopyranosyl backbone with a single beta-D-glucopyranosyl group at O-6 of every third glucose residue.
