[1] Tropane alkaloids occur naturally in many members of the plant family Solanaceae.
Certain tropane alkaloids such as cocaine and scopolamine are notorious for their psychoactive effects, related usage and cultural associations.
[2][3][4][5][6][7] Particular tropane alkaloids such as these have pharmacological properties and can act as anticholinergics or stimulants.
Anticholinergic drugs[8] and deliriants:[9] All three acetylcholine-inhibiting chemicals can also be found in the leaves, stems, and flowers in varying, unknown amounts in Brugmansia (angel trumpets), a relative of Datura.
The same is also true of many other plants belonging to subfamily Solanoideae of the Solanaceae, the alkaloids being concentrated particularly in the leaves and seeds.
