Atropa bella-donna, commonly known as deadly nightshade or belladonna, is a toxic perennial herbaceous plant in the nightshade family Solanaceae, [1] [2] which also includes tomatoes, potatoes and eggplant.
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.
Fruits including tomatoes, tomatillos, eggplant/aubergine, bell peppers and chili peppers, all of which are closely related members of the Solanaceae.. The Solanaceae (/ ˌ s ɒ l ə ˈ n eɪ s i. iː,-ˌ aɪ /), [3] or the nightshades, is a family of flowering plants that ranges from annual and perennial herbs to vines, lianas, epiphytes, shrubs, and trees, and includes a number of ...
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 ...
Solanine is a glycoalkaloid poison found in species of the nightshade family within the genus Solanum, such as the potato (Solanum tuberosum). It can occur naturally in any part of the plant, including the leaves, fruit, and tubers. Solanine has pesticidal properties, and it is one of the plant's natural defenses.
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).
Solanine is also found in other members of the Solanaceae plant family, which includes Solanum lycopersicum (tomato), Atropa belladonna (deadly nightshade), and Hyoscyamus niger (henbane) (see entries below). The concentration of glycoalkaloids in wild potatoes is sufficient to produce toxic effects in humans.
Solanum is a large and diverse genus of flowering plants, which include three food crops of high economic importance: the potato, the tomato and the eggplant (aubergine, brinjal). It is the largest genus in the nightshade family Solanaceae, comprising around 1,500 species.
