A mucous polysaccharide, named Lilium-A-glucomannan, has been isolated from the bulbs of Lilium auratum LINDL. It was homogeneous on glass-fiber paper electro-phoresis and by ultracentrifugal analysis. It was composed of D-mannose and D-glucose in the molar ratio of 8 : 3,and its molecular weight was estimated at 35700. The O-acetyl groups in it were identified and the content was 5.1%. The O-acetyl groups were located in both positions 3 and 6 of a part of D-mannose units. Methylation, periodate oxidation and partial acid hydrolysis studies suggested that the polysaccharide is mainly composed of β-1→4 linked aldohexopyranose residues having a small degree of branching at position 2 of D-mannose residues and the non-reducing ends were terminated by D-mannose units.
