A new indole alkaloid, leucoridine A N-oxide (1), consisting of two units of a strychnan type of skeleton, was isolated from the leaves of Leuconotis griffithii. Its structure was elucidated by various spectroscopic means such as NMR and MS, and also by chemical means. Antiplasmodial activity against Plasmodium falciparum 3D7 of indole alkaloids isolated from L. griffithii was investigated.
