From leaves and root bark of Pandaca ochrascens ten alkaloids were isolated: apparicine, akuammicine, dehydro-19,20 condylocarpine, akuammidine, epi-16 dehydro-14,15 vincamine, ibogaine, iboluteine, ibogaline and also two new alkaloids, epi-19 ibogaine or (19R) 19-hydroxyibogaine and epi-19 iboxygaline or (19R) 19-hydroxyibogaline. The absolute configuration at C19 of these new alkaloids and other alkaloids hydroxylated on 19 of the Iboga type is discussed. © 1974.
