Abstract
AbstractPositive‐ion fast‐atom bombardment (FAM) mass sspectrometry was used to ionize two indole alkaloids, namely trinervine and its quaternary metho‐salt venecurine containing a hemiketal ring system. Analysis of collision‐activated dissociation spectra by the technique of linked scanning at consltant B/E gave sturcturally useful information. Addition of concentratedf acid to the glycerol matrix yielded glycoside‐type derivatives from both compounds. These studies Provide further examples of an ‘acid effect’ on the protonation site of polyfunlctional molecules along with the possibility of their undergoing chemical mokification in the FAB matrix.
