  Present in several Iboga species, this base is slightly laevorotatory, having [α]_D - 5° (CHC13 ). It contains one methoxyl group, an imino group and a secondary hydroxyl group. It forms a crystalline p-toluenesulphonyl derivative, m.p. 267- 8°C. On catalytic reduction, the base furnishes ibogaine (q.v.). The structure has been determined from chemical and spectroscopic evidence to be decarbomethoxyvoacangarine.
