Opium poppy. Papaver somniferum, the Opium poppy, is the species of plant from which opium and poppy seeds are derived. Opium is the source of many narcotics, including morphine (and its derivative heroin), thebaine, codeine, papaverine, and noscapine. The Latin botanical name means the "sleep-bringing poppy", referring to the sedative properties of some of these opiates. The poppy is the only species of Papaveraceae that is an agricultural crop grown on a large scale. Other species, Papaver rhoeas and Papaver argemone, are important agricultural weeds, and may be mistaken for the crop. Argemone mexicana. Chemical constituents[edit] A. mexicana seeds contain 22–36% of a pale yellow non-edible oil, called argemone oil or katkar oil, which contains the toxic alkaloids sanguinarine and dihydrosanguinarine.
Four quaternary isoquinoline alkaloids, dehydrocorydalmine, jatrorrhizine, columbamine, and oxyberberine, have been isolated from the whole plant of Argemone mexicana.[4] Glaucium flavum.
