Analyses of oligosaccharide-malononitrile derivatives, which were obtained from the reactions of oligosaccharides with malononitrile under aqueous basic conditions, were conducted by on-line capillary liquid chromatography/electrospray ionization mass spectrometry in negative-ion mode. Among a varie

Disaccharides and linear oligosaccharides were labeled with p-aminobenzoic ethyl ester (ABEE) chromophore and analyzed by negative ion electrospray ionization mass spectrometry (ESIMS). The formation of glycosylamines rather than reductive amination in the labeling reaction produced many characteris
