Gabunia

Ervatamia, Gabunia, Hazunta, Muntafara, Pagiantha, Pandaca, Peschiera, Phrissocarpus, and Stenosolen, All of these contain alkaloids related to Ibogaine. 

A characteristic of the genera Callichilia, Conopharyngia, Gabunia, Stemmadenia, Tabernaemontana, and Voacanga of the Apocynaceae family is the presence of bisindole alkaloids of the voacamine type, the prototype of this group being voacamine itself. All these alkaloids are composed of a vobasine-like [vobasine,... 

Gabimine (165), Conodurine (166), and Conoduramine (167).—Gabunine (165), from the Apocynaceae Gabunia odoratissima Stapf. contains, in contrast to the previously described bisindole alkaloids of this group, no JV-methyl function. 

When NMR and mass spectrometry became available, a large number of alkaloids from various apocynaceous plants were investigated (e.g. species of the genera Alstonia, Aspidosperma, Conopharyngia, Gabunia, Hunteria, Iboga, Oncinotis, Rauwolfia, Vinca). Villalstonine was the first bisindole alkaloid whose structure was elucidated by mass spectral analysis. 

A bisindole alkaloid isolated by the French group from Gabunia eglandulosa appears not to be voacamine, and may be new ten others, so far of unspecified structure, have been extracted from Muntafara sessilifolia, and a group of four, from Pandaca caducifolia, belong to a new structural type, but their structures have not yet been elucidated in detail.
