Akuammine (vincamajoridine^[2]) is an indole alkaloid. It is the most abundant alkaloid found in the seeds from the tree Picralima nitida,^[3] commonly known as akuamma, comprising 0.56% of the dried powder. It has also been isolated from Vinca major.^[2] Akuammine is structurally related to yohimbine, mitragynine and more distantly Voacangine, all of which are alkaloid plant products with pharmacological properties.

Pharmacology

Akuammine has antimalarial activity,^[3] and may be the primary constituent of P. nitida seeds responsible for this activity.^[4]

Akuammine is an opioid agonist with low affinity, selective for the mu-opioid receptor, when tested in vitro.^[5]^[6]
