Rauwolscine, also known asisoyohimbine,α-yohimbine, andcorynanthidine, is analkaloid found in various species within the generaRauvolfia andCorynanthe (includingPausinystalia).[1] It is astereoisomer ofyohimbine.[1] Rauwolscine is acentral nervous systemstimulant, alocal anesthetic and a vagueaphrodisiac.[1]

Rauwolscine acts predominantly as aα2-adrenergic receptorantagonist.[2][3] It has also been shown to function as a5-HT1A receptorpartial agonist and5-HT2A and5-HT2B receptorantagonist.[4][5][6]
