Alkaloids From Egyptian Papaver rhoeas
Planta Medica, 1981N-methylasimilobine was isolated as the major alkaloid from an Egyptian sample of P. RHOEAS L. Other alkaloids isolated from the same plant material were stylopine, coptisine, isocorydine and rhoeadine. Chromatography indicated the presence of at least nine other minor alkaloids.

QUANTIFICATION OF ESSENTIAL ELEMENTS IN PAPAVER RHOEAS L. AND PAPAVER SOMNIFERUM
Book of Proceedings: 1st International Conference on Chemo and BioInformatics, 2021Plants are very important for proper human nutrition, so the content of essential elements was investigated in two poppy species. Essential elements such as Ca, Na, K, Mg, Fe, Cu, Co, Mn, Mo and Zn play a vital role in various biological processes. Samples of roots, stems, leaves and seeds of Papaver rhoeas L. and Papaver somniferum were acid dissolved

In this paper, we report a case of misidentification of medicinal plants involving dried petals of Papaver rhoeas (red poppy) contaminated with Papaver bracteatum (scarlet poppy) petals. Preliminary TLC analysis indicated the presence of thebaine either in the fluid extracts or in the petals.

Colour development and pigment characterisation in flowers of Papaver nudicaule and Papaver rhoeas
2021The present thesis extended the knowledge about floral pigments and volatiles and their role in plant-pollinator interaction in two widely distributed Papaver species. The bright red flowers of P. rhoeas, the corn poppy, are characterised by a highly variable colouration in the UV-A wavelength range depending on geographical distribution.

Molecular basis of resistance to sulfonylureas in Papaver rhoeas
Pesticide Biochemistry and Physiology, 2004Abstract A Papaver rhoeas population resistant to several acetolactate synthase (ALS) inhibiting herbicides, called 25/98, was found in Catalonia (Northeastern of Spain). This population has an altered form of the enzyme that showed cross-resistance to several herbicides of this group.
