Tabernaemontanine
Tabernaemontanine is a naturally occurring monoterpene indole alkaloid found in several species in the genus Tabernaemontana including Tabernaemontana divaricata. == History == Tabernaemontanine was first reported in 1939 but its structure was only fully confirmed in the 1970s as there was confusion in the original literature regarding the configuration of the ethyl group in the piperidine ring of this alkaloid and its isomer dregamine, so that their identities had been reversed.
