Naturally occurring hyoscine is a combination of laevo-tropic acid with inactive hyoscine. It is found, mostly in conjunction with hyoscyamine, in many species of Datura. In D. arborea, D. fastuosa, and D. metel, the alkaloid consists chiefly of hyoscine whilst D. stramonium contains principally hyoscyamine, with some hyoscine. It is present also in Scopolia and Hyoscyamus species, for instance in Scopolia japonica and Hyoscyamus niger. 

Scopolamine is found in the leaves of Datura metel L., D. meteloides L., and D. fastuosa var. alba (Cordell 1978). It is used as a sedative, a preanesthetic agent, and in the treatment of motion sickness (Merck 1989).
