## Abstract 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
We wish to report a photo-oxidative cleavage reaction of some benzylisoquinoline-based alkaloids, which should be particularly useful in structural studies of bisbenzylisoquinolines not readily amenable to the usual degradative methods. Ultraviolet irradiation' of laudanosine (I) in the presence of
