The following 12 known alkaloids were isolated from the fruits (f), leaves (lv), trunk-barks (t) and root-bark (r-b) of Tabernanthe pubescens: coronaridine reaves (iv), voaphylline (iv), tetrahydroalstonine (iv), voaphylline hydroxy-indolenine (iv), (f), tetrahydroalstonine (iv), voaphylline hydroxy-indolenine (iv), 11-hydroxy tabersonine (iv), ibogamine (t), ibogaine (t, r-Four new alkaloids were also isolated. These were 3,6-oxido iboxygaine (t), Four lies were also isolated. These were established through chemical correlations with the parent (p), showed in the parent (p), whose structures were established through chemical correlations with the parent alkaloids.
