%X Extraction of the aerial parts of Ophiorrhiza cf. ferruginea ( Rubiaceae ) has yielded the tertiary indole alkaloids dihydrocycloakagerine (1), 3,14-dihydrodecussine (mostuenine) (3) and tetrahydroakagerine (4), and the quaternary indole alkaloid isomalindine (5). The structures of dihydrocycloakagerine (1) and isomalindine (5) are confirmed by the X-ray method.
