„Hyoscyamine (atropine) and scopolamine are the predominant tropane alkaloids in the Datura genus, occurring in all plant organs… D. innoxia showed the highest concentrations of scopolamine in all organs examined, whereas D. metel accumulated the lowest scopolamine levels. Hyoscyamine, measured as atropine, was the highest in D. stramonium var. tatula, and the lowest in D. innoxia.“
