title: Chromatography of permethylated oligosaccharide alditols.
abstract: A new chromatographic method which enables the separation of permethylated oligosaccharide alditols has been developed. The method entails chromatography on precoated silica gel plates using benzene-methanol (16:1, v/v or 10:1 v/v) as developing solvent. Separations of disaccharides were obtained on the basis of glycosidic linkage and anomeric configuration; the method can accomodate oligosaccharides containing up to 15 glycose units. The combined use of thin-layer chromatography and gas-liquid chromatography provides a powerful approach for the characterization of oligosaccharides. Retention indices are given of permethylated oligosaccharide alditols on a fused-silica capillary column bonded with DB-1.
