Mitraphylline, an oxindole derivative, is an active alkaloid in the leaves of the tree Mitragyna speciosa, commonly known as kratom.^[1] As a non-narcotic constituent, it also occurs to a significant amount in the bark of Uncaria tomentosa (Cat's Claw) along with a number of isomeric alkaloids.^[2]
