Two new erythrinan alkaloids, named erythlaurine and erythramide, and the known alkaloids stepholidine (XII) and O-methylflavinantine (XIII) were isolated from the leaves of Cocculus laurifolius. On the basis of chemical and spectroscopic evidence, the structures of erythlaurine and erythramide were determined as VII and X, respectively.
