摘要：

A series of anomeric unsaturated C-glycosides were studied by negative ion mass spectrometry following keV ion bombardment. The compounds bearing an acidic hydrogen show a prominent [M - H]- peak; in the other cases, the [M - H]- peak is of very low intensity. A retro-Diels-Alder fragmentation and the abstraction of a hydrogen atom from the aglycon residue are observed in all cases.
