Voacristine

Voacristine is a indole alkaloid occurring in Voacanga and Tabernaemontana genus. It is also an iboga type alkaloid.

Chemistry
Its structure is almost similar to voacangine, an alkaloid used in semi-synthesis of ibogaine. Compared to voacangine, it has an extra O-atom. When it is degraded, iboxygaine and ibogaine are formed.
