Tetradium ruticarpum Identity & Plant Part
The botanical entity is Tetradium ruticarpum (A.Juss.) T.G.Hartley, a small tree of the Rutaceae, formerly filed as Evodia rutaecarpa. The part used is the fruit, a small, rounded, five-lobed capsule collected before it opens. Leaves, bark and roots are not part of this ingredient. Fruit size and maturity vary between lots and affect the chemistry.
The best-known constituents are indoloquinazoline alkaloids such as evodiamine and rutaecarpine, together with limonoid bitter principles and a volatile oil, named here as families only. Those alkaloids dissolve poorly in water, so a Tetradium ruticarpum water extract is not an alkaloid concentrate, and no alkaloid percentage is stated on this entry.
