From the epigeal part ofHaplophyllum dubium we have isolated dubamine, γ-fagarine, skimmianine, graveoline, haplopine, the new alkaloid norgraveoline, and the steroid β-sitosterol. This is the first time that γ-fagarine has been found in this plant. On the basis of the results of a study of spectral characteristics and also passage to the known alkaloid graveoline, it has been established that norgraveoline has the structure of 2-piperonyl-4-quinolone.
