Fractionation of the deacetylated acetolyzate of the borate-soluble fraction of the dextran elaborated by Leuconostoc mesenteroides MRRL B-1299 gave, after chromatography on charcoal-Celite, preparative paper-chromatography, and paper electrophoresis, four trisaccharide fractions and four 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 shown to be (a) kojitriose (1), (b) isomaltotriose (2), (c) a mixture of 2-O-α-isomaltosyl-D-glucose (3), 21-O-α-D-glucosylisomaltose (4), and 2-O-α-nigerosyl-D-glucose (5), (d) 6-O-α-kojibiosyl-D-glucose (6), (e) isomaltotetraose (7), (f) a mixture of 2-O-α-isomaltotriosyl-D-glucose (8) and 21-O-α-D-glycosylisomaltotriose (9), (g) 6-O-α-kojitriosyl-D-glucose (10), and (h) 63-O-α-D-glucosylkojitriose (11), respectively.Some of these oligosaccharides are newly isolated and characterized.
