  Acetolysis of Leuconostoc mesenteroides NRRL B-1299 dextran. Isolation and characterization of oligosaccharides containing secondary linkages from the borate-soluble fraction

  摘要：

  Fractionation of the deacetylated acetolyzate of the borate-soluble fraction of the dextran elaborated by L. mesenteroides NRRL B-1299 gave, after chromatography on charcoal-Celite, preparative paper-chromatography, and paper electrophoresis, 4 trisaccharide fractions and 4-tetrasaccharide fractions. The isolated oligosaccharides were characterized by their paper-chromatographic mobility, examination of partial acid-hydrolyzates of the oligosaccharides and their corresponding alditols, and methylation analysis. These oligosaccharides were kojitriose, isomaltotriose, a mixture of 2-O-.alpha.-isomaltosyl-D-glucose, 21-O-.alpha.-D-glucosylisomaltose and 2-O-.alpha.-nigerosyl-D-glucose, 6-O-.alpha.-kojibiosyl-D-glucose, isomaltotetraose, a mixture of 2-O-.alpha.-isomaltotriosyl-D-glucose and 21-O-.alpha.-D-glucosylisomaltotriose, 6-O-.alpha.-kojitriosyl-D-glucose and 63-O-.alpha.-D-glucosylkojitriose, respectively. Some of these oligosaccharides are newly isolated and characterized.
