DIVERSIDAD GENÉTICA Y MEJORAMIENTO DE PLANTAS MEDICINALES= Medicinal plants and improvement of medicinal herbs:

The allergenic pollen of Argemone mexicana L. a common road-side weed was subjected to artificial SO2 fumigation at a concentration of 100 ppm for 24 hours, 48 hours and 72 hours and its effect on the total carbohydrate, lipid, free amino acid, DNA and RNA content as well as peroxidase isozyme and DNA profile studied. In comparison to the control (pollen exposed to charcoal-filtered air), the carbohydrate, lipid, DNA and RNA content decreased with the increase in the time of exposure to SO2, where as the percentage composition of free amino acid increased. Contrary, to this, the activity of peroxidase was found to increase with a change in the iso-peroxidase zymogram showing three new anionic isozyme bands. SO2 affected the total DNA profile leading to the gradual breakdown of DNA with several bands observed on agarose gel electrophoresis with an increase in the time of fumigation.

Argemone mexicana (Papaveraceae) is a weed native to Mexico and Southern USA, although at present it can be found widespread throughout the continent, reaching some areas of Patagonia. Also known by the common name of Mexican poppy, the presence of toxic alkaloids has limited the medicinal use of this plant. However, some of these compounds have shown interesting pharmacological data, mostly in the fields of cardiology and infectology, and more recently as an interesting option in the clinical treatment of malaria. Some authors, however, strongly advice against the use of A. mexicana under any circumstance.
