Voacristine is a indole alkaloid occurring in Voacanga and Tabernaemontana genus. It is also an iboga type alkaloid.^[1]

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.^[2]

Sources

Voacristine is found in multiple species of Tabernaemontana including Tabernaemontana divaricata,^[3] Tabernaemontana heyneana,^[4] Tabernaemontana ventricosa,^[5] and Voacanga africana.^[6]
