Mixtures of partially O-methylated alditol acetate standards of galactofuranose were synthesized rapidly. Methyl galactofuranosides were obtained with a yield of 79.9% within 4 h under optimized reaction conditions. Methylation of methyl glycosides was carried out in the presence of BaO/Ba(OH)2·8H2O, giving rise to mixtures of partially methylated glycosides. The batch containing the most diverse structures of methyl ethers was converted into partially O-methylated alditol acetates (PMAAs) and then subjected to GC-MS. These PMAAs could be used as GC-MS standards for simultaneous identification of galactofuranose units with diverse linkages in complex carbohydrates.

The structure of the capsular polysaccharide isolated from Klebsiella K68 bacteria has been elucidated by both chemical and spectroscopic methods.The structure is of the "3+1" type, similar in pattern to the structures of the polysaccharides of Klebsiella K11 and K57, having a single branch point on the uronic acid.The polysaccharide is shown to consist of the following repeating unit:
