During the investigation of a polysaccharide prepared by polymerising maltose the following compounds have been separated by gas-liquid chromatography on a column of SF 96: (1) 1-O-(α- d -glucopyranosyl)-glycerol, (2) 1-O-(β- d -glucopyranosyl)-glycerol, (3) 2-O-(α- d -glucopyranosyl)-glycerol, (4) 2-O-(β- d -glucopyranosyl)-glycerol, (5) 1-O-(α- d -glucopyranosyl)-erythritol, (6) 1-O-(β- d -glucopyranosyl)-erythritol, (7) 2-O-(α- d -glucopyranosyl)-erythritol, (8) 2-O-(β- d -glucopyranosyl)-erythritol, (9) 1-O-(α-maltosyl)-glycerol, (10) 1-O-(β-maltosyl)-glycerol, (11) 1-O-(α-maltosyl)-erythritol, (12) 1-O-(β-maltosy)-erythritol, (13) 2-O-(α-maltosyl)-glycerol, (14) 2-O-(β-maltosyl)-glycerol, (15) 2-O-(α-maltosyl)-erythritol, (16) 2-O-(β-maltosyl)-erythritol. Compounds 13–16 were only tentatively indentified. The methylated polysaccharide indicated that some hydrolysis to glucose and recombination occurred during polymerisation. There was a small percentage of glucofuranose units. |
