Abstract

In addition to the konwn alkaloids from Papaver oreophilum F. J. RUPR., i.e. oridine, mecambridine, isocorydine, protopine, oreodine, rhoeadine, nuciferine, isooridine (oridine-2), oridine-3, alkaloid PO-5 (R-K, alborine) and trace alkaloids rhoeagenine, oreogenine, isorhoeadine, papaverrubines A, D and E, sanguinarine, N-methyloridine and coptisine, we isolated from the aerial part or from the roots the following further alkaloids: allocryptopine and - from the quaternary fraction - menisperine and magnoflorine (3.6%), which is the main alkaloid in the roots. Further corydine and trace amounts of papaverrubine C, chelirubine, berberine, corysamine and probably O-methyloridine and O,N-dimethyloridine were also detected. It was shown that oridine-3 was identical with the hydrochloride of isooridine.
