Argemone mexicana L. - Papaveraceae
prickly poppy, Mexican poppy, Mexikanischer Stachelmohn, Mexikanische Distel
Annual herb to 1m high, native to central America, cultivated for centuries, naturalized in many tropical and subtropical regions; plant with bright yellow latex; stems, leaves and sepals spiny; leaves usually blotched with paler green; flowers closely subtended by the upper leaves, yellow or cream, 3-6 cm wide.
„Fractionation of the chloroform extract from the aerial part of Argemone mexicana led to the isolation of two benzophenanthridine-type alkaloids, N-demethyloxysanguinarine and pancorine; three benzylisoquinoline-type alkaloids, (+)-1,2,3,4-tetrahydro-1-(2-hydroxy-methyl-3,4-dimethoxyphenylmethyl)-6,7-methylenedioxyisoquinoline, (+)-higenamine and (+)-reticuline.“

„Four quaternary isoquinoline alkaloids, dehydrocorydalmine, jatrorrhizine, columbamine, and oxyberberine, have been isolated from the whole plant of Argemone mexicana Linn. (Papaveraceae) and their structures established by spectral evidence.“
