Two kinds of acidic polysaccharides, MEA ([α]²³_D+31°) and MHA ([α]²³_D+33°), have been isolated from the hot aqueous 70% ethanol and hot water extracts of the fruit bodies of Auricularia auricula-judae QUEL, which grow in China. Both polysaccharides were homogeneous as judged by gel filtration, electrophoresis and ultracentrifugal analysis. They were composed of D-glucuronic acid, D-xylose and D-mannose in molar ratios of 1.0 : 0.5 : 2.8 (MEA) and 1.0 : 0.6 : 1.0 (MHA), together with a small amount of D-glucose, and contained O-acetyl groups. The molecular weights were estimated to be 37×10⁴ for MEA and 30×10⁴ for MHA. The results of methylation, Smith degradation and partial acid hydrolysis studies suggested that MEA and MHA were constructed with α-1→3 linked D-mannopyranose residues as a backbone, some of which were substituted at position 2 with terminal β-D-glucopyranosyluronic acid residues, and at position 2 and position 6 with single residues or short chains of β-D-xylopyranose. Further, MEA and MHA appear to contain small amounts of 1→6 linked D-mannopyranose (glucose) and branching D-mannopyranose residues at positions 4 and 6. MEA and MHA differ significantly in the amounts of O-acetyl groups, 1→4 linked D-xylopyranose residues and the branching D-mannopyranose residues at positions 4 and 6.
