Corynanthine, also known asrauhimbine, is analkaloid found in theRauvolfia andCorynanthe (includingPausinystalia) genera of plants.[1][2] It is one of the twodiastereoisomers ofyohimbine, the other beingrauwolscine.[3][4] It is also related toajmalicine.

Corynanthine acts as anα1-adrenergic andα2-adrenergic receptorantagonist with approximately 10-foldselectivity for the former site over the latter.[3][4] This is in contrast to yohimbine and rauwolscine which have around 30-fold higher affinity for the α2-adrenergic receptor over the α1-adrenergic receptor.[3][4] As a result, corynanthine is not astimulant (or anaphrodisiac for that matter), but adepressant, and likely plays a role in theantihypertensive properties ofRauvolfia extracts. Like yohimbine and rauwolscine, corynanthine has also been shown to possess some activity atserotonin receptors.[5]
