Papaver argemone L. and Papaver pavoninum FISCH. et MEY. species of the Argemonorhoeades FEDDE (Papaveraceae) section were studied. A very low content of alkaloids was found in both species (less than 0·05%). P. argemone contains corytuberine and its quaternary N-methyl derivative magnoflorine as the dominant bases. As minor constituents were isolated: protopine, isocorydine, scoulerine, and alkaloids PAR 1, PAR 2, PAR 3. Chromatographic analysis detected allocryptopine, cryptopine, coptisine and traces of rhoeadine, papaverrubines C, D and E, and more than 6 unidentified bases. P. pavoninum gave N2-methyl-1,2,3,4-tetrahydro-β-carboline as the dominant alkaloid, along with minor amounts of the tertiary bases protopine, allocryptopine, corydine, isocorydine and corytuberine. Of quaternary bases, coptisine, magnoflorine and an unidentified alkaloid PP 1 were isolated. The presence of many other, considerably labile bases has been proven in both species.
