The best-known member of the genus Atropa is deadly nightshade (A. belladonna) – the poisonous plant par excellence in the minds of many. [8] The pharmacologically active ingredients of Atropa species include atropine, scopolamine, and hyoscyamine, all tropane alkaloids having anticholinergic, deliriant, antispasmodic and mydriatic properties.
deadly nightshade, belladonna, devil's cherry, dwale Solanaceae: One of the most toxic plants found in the Western Hemisphere, all parts of the plant contain tropane alkaloids [61] – as do those of its equally deadly sister species A. baetica, A. pallidiflora and A. acuminata.
Nightshade vegetables come from the Solanaceae family of flowering plants, which are nutritional powerhouses, packed with vitamins (such as C and K), minerals (like potassium and magnesium), and ...
Naturally-occurring anticholinergic deliriants are found in the plant species Atropa belladonna (deadly nightshade), various Brugmansia species (Angel's Trumpets), Datura stramonium (Jimson weed), Hyoscyamus niger (henbane), and Mandragora officinarum (mandrake) in the form of the tropane alkaloids scopolamine, atropine, and hyoscyamine.
Hyoscyamine (also known as daturine or duboisine) is a naturally occurring tropane alkaloid and plant toxin. It is a secondary metabolite found in certain plants of the family Solanaceae, including henbane, mandrake, angel's trumpets, jimsonweed, the sorcerers' tree, and Atropa belladonna (deadly nightshade).
In India, another strain is found with berries that turn red when ripe. [7] Sometimes S. nigrum is confused for the more toxic deadly nightshade (Atropa belladonna), which is in a different genus within Solanaceae. A comparison of the fruit shows that the black nightshade berries grow in bunches, whereas the deadly nightshade berries grow ...
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.
