Détermination des teneurs en atropine et scopolamine de différentes espèces sauvages et ornementales du genreDatura

Abstract: Résumé -Introduction : Le genre Datura fait partie de la famille des solanacées, vaste de plusieurs milliers d'espèces. Ce genre se caractérise par une production importante d'alcaloïdes tropaniques : hyoscyamine, atropine et scopolamine. L'objectif de cette étude est d'apprécier la dangerosité de certaines espèces ornementales par rapport aux espèces sauvages en déterminant leurs concentrations respectives en atropine et scopolamine. Méthodes : Cinq plants d'origine sauvage (Datura stramonium et inoxia) et de… Show more

“…Recent analysis of hair of patients suffering from Datura poisoning revealed atropine (8.4-15.0 pg/mg) and scopolamine (1.0-1.3 pg/mg) in a patient who admitted regular consumption of Datura stramonium 113 , and only scopolamine (14 to 48 pg/mg) in a regular Cannabis abuser who had consumed six dried flowers of D. inoxia in hot water 114 . These data are consistent with phytochemical studies that show that the ratio of scopolamine to www.nature.com/scientificreports/ atropine is substantially higher in D. inoxia than in D. stramonium 115,116 . The high ratio of scopolamine to atropine found in the hair from the cave of Es Càrritx cannot be associated with the use of D. inoxia since this is not a species native to the Old World.…”

“…La Datura inoxia présente des concentrations en atropine faibles et de fortes concentrations en scopolamine. Pour l'espèce ornementale Datura wrightii, les concentrations retrouvées en atropine sont relativement faibles [2].…”

“…Atropine is a racemic mix of the R-and L-enantiomer of hyoscyamine (tropane alkaloids from Datura stramonium, wrightii, Solanaceae family) [1]. Its anticholinergic effects are due to its binding to muscarinic acetycholine receptors which are widely distributed throughout the body [2].…”

“…Atropine sulfate was used therapeutically as antispasmodic drug in gastroenterology, cardiology and ophtalmology [3]. It is also used as an antidote for insecticide poisoning [3], and sometimes used for addiction and criminal purposes [1]. The drug is readily absorbed from the intestine but not from the stomach [4].…”
