Ibogaline
Alkaloid found in Tabernanthe iboga
From Wikipedia, the free encyclopedia
Ibogaline is an alkaloid found in Tabernanthe iboga along with the related chemical compounds ibogaine, ibogamine, and other minor alkaloids. It is a relatively smaller component of Tabernanthe iboga root bark total alkaloids (TA) content. It is also present in Tabernaemontana species such as Tabernaemontana australis[1] which shares similar ibogan-biosynthetic pathways. The percentage of ibogaline in T. iboga root bark is up to 15% TA with ibogaine constituting 80% of the alkaloids and ibogamine up to 5%.[2][3]

Chemistry
Derivatives
Kisantine and Gabonine are thought to be ibogaline's oxidation byproducts.[4]
Adverse effect
In rodents, ibogaline induces more body tremor and ataxia compared to ibogaine and ibogamine.[5] Among a series of iboga and harmala alkaloids evaluated in rats, the study authors found the following order of potency in causing tremors:[5]
- ED50 (μmol/kg, sc): tabernanthine (4.5) > ibogaline (7.6) > harmaline (12.8) > harmine (13.7) > ibogaine (34.8) > noribogaine (176.0)
A subsequent study confirmed these findings.[6]
