Eschscholtzia oregana

Eschscholtzia oregana, and E. califomica and the /3-form in Glaucium comiculatum, Papaver rhoeas, and P. syriacum. The alkaloid content of Argemone mexicana, and particularly the presence of four quaternary bases, namely (—)-/3-scoulerine methohydroxide, (-)-cheilanthifoline, and both the a- and /8-methohydroxides of (-)-stylopine, suggests a close relationship between this plant and A. ochroleuca and A. albiflora (cf Vol. 5). ° Similarly, the presence of (-)-scoulerine and the benzophenanthridine norchelerythrine in A. polyanthemos confirms its close biochemical relationship with A. albiflora. ... [Pg.143]

Species belonging to the section Stenocraspedontae are characterized by the presence of benzylisoquinoline alkaloids, for example, E. oregana Greene contains escholamine (33) as the major alkaloid. Eschscholtzia lobbii Greene appears to be exceptional since neither pavine nor benzylisoquinoline alkaloids have been detected therein. The presence of aporphine alkaloids is characteristic for all the species. [Pg.40]
