Popis: The mass spectra of several naturally occuring Sceletium alkaloids, as well as several synthetic variants, have been investigated. Techniques used include high resolution mass measurements, analysis of metastable transitions by the technique of ion defocusing and specific deuterium labeling in conjunction with low resolution mass spectrometry. Characteristic major fragmentation pathways have been determined for four basic structure types studied: the cis-3a-aryl-octahydroindole ring system, exemplified by mesembrine; its 2,3-pyrido analog, Sceletium A4; the seco series of pyridine bases, represented by tortuosamine; and the seco analog of the mesembrine-type represented by tortuosamine; and the seco analog of the mesembrine-type represented by dehydrojoubertiamine.
