FRAGMENTATION OF DEPROTONATED PLUMERAN INDOLE ALKALOIDS BY ELECTROSPRAY IONIZATION TANDEM MASS SPECTROMETRY

FRAGMENTATION OF DEPROTONATED PLUMERAN INDOLE ALKALOIDS BY ELECTROSPRAY IONIZATION TANDEM MASS SPECTROMETRY

The fragmentation of four deprotonated plumeran indole alkaloids (PIAs), namely aspidospermidine (1), demethoxypalosine (2), aspidocarpine (3), and aspidolimine (4), previously isolated from Aspidosperma spruceanum has been investigated by electrospray ionization tandem mass spectrometry (ESI-MS/MS)...
