Following the isolation of phenolic bases, nuciferine and roemerine, and a phenolic base, nornuciferine (I), from the leaves and petioles of lotus (Nelumbo nucifera GAERTN.), another base was isolated from the mother liquor left after separation of nornuciferine. The base was isolated as a crystalline oxalate of m. p. 211-212° and this was proved to be dl-armepavine (III).
