Highly branched xyloglucan oligosaccharides were analyzed by the post-source decay (PSD) fragmentation method of matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS). The ratio of [M-Xyl] + and [M-Gal] + fragment ion intensities could be used to characterize the degree of Gal substitution at the non-reducing end, because the number of possible chemical species was directly related to their relative ion intensity. The intensity of the [M-Fuc] + ion was predominantly strong in the fragment spectrum of fucosyl oligosac-charides as the first fragmentation, indicating the fucosyl linkage to be much weaker than the other glycosidic link-ages in the MALDI-PSD fragmentation. Setting fragment ion [M-Fuc] + to the pseudo precursor ion [MF] +, the second fragmentation ions were produced from [MF] + in the drift region in PSD fragmentation of fucosyl oligosaccharides.
