Abstract

A post‐source decay matrix‐assisted laser desorption/ionization mass spectrometric (PSD‐MALDI‐MS) study of rutin, a naturally occurring flavone glycoside cationized with different alkali metal ions, is reported. The fragmentations of rutin were performed by selecting the [R + Cat]^+^ peaks for PSD, where R represents a rutin molecule and Cat an alkali metal ion (Li^+^, Na^+^, K^+^). The PSD‐MALDI mass spectra showed, depending on Cat, different fragmentation patterns with respect to both the quality and quantity of the fragment ions formed. The intensity of fragmentation decreased in the order Li^+^ > Na^+^ > K^+^. The fragmentation mechanism and an explanation for the observed differences are suggested.

Post-source decay fragment analysis using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOFMS) has been applied to a highly branched xyloglucan heptasaccharide from tamarind seed. All fragment ions were produced by cleavage of the glycosidic linkages, including
