Partition on Celite columns, using both elution and extrusion techniques, was found to be a convenient and satisfactory chromatographic method for preparative or analytical work involving carbohydrates and their derivatives. The method is superior to other chromatographic procedures for carbohydrates in resolution of mixtures; cost, ease, and speed of operation; yield and purity of products; and range of applicability. To illustrate these advantages a number of specific examples are given involving partially methylated derivatives of D-glucose and D-xylose and isolation of products from reaction mixtures.

Individual fructan tri-, tetra- and pentasaccharide isomers in neutral, water-soluble extracts from Lolium temulentum were purified and the linkages present in these isomeric oligosaccharides were analysed by combined GC-mass spectrometry of partially methylated alditol acetates. 1-Kestose and neokestose were the most abundant trisaccharides with 6-kestose present in much lower amounts. Analysis of isomers of DP 4 and 5 showed that multiple linkage types were present with structures based on all three trisaccharides. Oligosaccharides based on neokestose but with 2,6 linkages between adjacent fructose residues have not been previously detected in higher plants. © 1992.
