Affinine is a monoterpenoid indole alkaloid which can be isolated from plants of the genus Tabernaemontana.[1][2] Structurally it can be considered a member of the vobasine alkaloid family and may be synthesized from tryptophan.[3] Limited pharmacological testing has indicated that it may be an effective inhibitor of both acetylcholinesterase and butyrylcholinesterase.[4]
