Tabernanthe orientalis, also called Tabernaemontana orientalis.
This plant is now called Ervatamia orientalis, and is found in Western Australia.
The leaves contain ibogaine, along with six minor alkaloids that are closely related, structurally.

Tabernaemontana orientalis (syn Ervatamia orientalis)
Australian Ibogaine Bush, Iodine Bush

Botanical information
An evergreen shrub, it grows to a height of 2.5m with a spread of 2m.
The stem is erect and branching; the leaves are opposite, thick, smooth, 10-15cm long and narowly ovate-acuminate; the flowers are white, and expanding tubular.
A native of Australia, India and some areas of the Pacific....

Traditional uses

The common name 'iodine bush' arose from its reputed use by Aborigines to cure sores and ulcers.
It belongs to a family with many toxic members and this one has been suspected of poisoning horses and cows.
However, there is no record of human poisoning and it appears that the protein-breaking enzymes, and possibly even antibiotics, in the milky latex may actually have healing properties.
It has also been called Bitter Bark and has found use as a quinine substitute in colonial times.
This Tabernaemontana is a close relative of the Tabernanthe iboga bush, which is used ritually in Africa.

Alkaloids of Ervatamia orientalis
Knox & Slobbe
Aust J Chem #28: 1813-56, 1975.

In this study leaves and bark of different Australian specimens were quantitavely and qualitatively analysed for their alkaloids.
In the leaves the alkaloids isolated,at about 0.22% yield, were ibogaine, iboxygaine, ervatamine, 19-dehydroervatamine and apparacine. in the ratios of 1.8 : 0.25 : 0.5 : 1 : 2 respectively.

Three samples of bark were found to contain 1.3 %, 2 % and 1.4 % alkaloids.
The alkaloids were found to be a mixture of ervatamine, tabernaemontanine, 16-demethoxycarbonyl-20�-epidihydro-voacamine, 20-epiervatamine, dregamine, 19-dehydroervatamine, vobasine, voacamine, 16-demethoxycarbonyl-dihydro-voacamine and voacristine.

The following alkaloids are of the ibogan type, ibogaine, iboxygaine and voacristine.

The alkaloids voacamine, 16-decarbomethoxy-19,20-dihydrovoacamine and 16 decarbomethoxy-19,20-dihydro-20-epi-voacamine are actually dimeric alkaloids constructed from a single ibogaine molecule combined with either a dregamine or tabernaemontanine molecule.


Just for interest sake'

Treatment of Voacamine with pot-ash and micro-waves yields Ibogaine'
A large majority of Ibogaine hcl in the world is made this way'
