Abstract Mass spectra have been determined of a number of phloroglucinol derivatives and closely‐related compounds encountered in chemical studies of hop components. Initial fission involving acyl, alkyl or alkenyl side‐chains gives predominantly even‐electron ions which then fragment their oxygen heterocyclic rings by elimination of neutral molecules, whilst gem ‐dialkenyl centres show preference for loss of an alkenyl group. The fragment ions induced by electron‐impact may be correlated to a useful extent with molecular structure.
