Solanine is a glycoalkaloid poison found in species of the nightshade family within the genus "Solanum", such as the potato ("Solanum tuberosum"), the tomato ("Solanum lycopersicum"), and the eggplant ("Solanum melongena").
 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.
 Solanine was first isolated in 1820 from the berries of the European black nightshade ("Solanum nigrum"), after which it was named.
Solanum douglasii is a species of nightshade known by the common name greenspot nightshade.
Withania somnifera, known commonly as ashwagandha, Indian ginseng,padalsingh (rajasthan), poison gooseberry, or winter cherry, is a plant in the Solanaceae or nightshade family.
 Several other species in the genus "Withania" are morphologically similar.
 It is used as a herb in Ayurvedic medicine.
Solanum aculeastrum is commonly known as soda apple, sodaapple nightshade, goat apple, poison apple, or more ambiguously as "bitter-apple".
 It is a poisonous nightshade species from Africa and not related to true apples.
 The term "soda apple" probably derives from "Sodom apple", modified due to the fruit's detergent properties.
Toxicodendron is a genus of flowering plants in the sumac family, Anacardiaceae.
 It contains woody trees, shrubs and vines, including poison ivy, poison oak, and the lacquer tree.
 All members of the genus produce the skin-irritating oil urushiol, which can cause a severe allergic reaction.
 The generic name is derived from the Greek words τοξικός ("toxikos"), meaning "poison," and δένδρον ("dendron"), meaning "tree".
 The best known members of the genus in North America are poison ivy "(T. radicans)", practically ubiquitous throughout most of eastern North America, and western poison oak ("T. diversilobum"), similarly ubiquitous throughout much of the western part of the continent.
Dioscorine is an alkaloid toxin isolated from the tubers of tropical yam on several continents.
 It has been used as a monkey poison in some African countries, and as an arrow poison to aid in hunting in several parts of Asia.
 It was first isolated from "Dioscorea hirsute" (synonymous with "Dioscorea hirsuta") by Boorsma in 1894 and obtained in a crystalline form by Schutte in 1897, and has since been found in other "Dioscorea" species.
 Dioscorine is a neurotoxin that acts by blocking the nicotinic acetylcholine receptor.
 Dioscorine is generally isolated in tandem with other alkaloids such as dioscin but is usually the most potent toxin in the mixture.
 It is a convulsant, producing symptoms similar to picrotoxin, with which it shares a similar mechanism of action.
 (Dioscorine is not to be confused with dioscorin, the yam storage protein.)
Cassaine is a toxic compound found within the "Erythrophleum" genus of trees.
 This genus has a range from Senegal to Sudan and Kenya in the east, and south to Zimbabwe and Mozambique.
 Cassaine was first isolated by the G. Dalma group in 1939 from the "Erythrophleum guinneese" tree.
 Since ancient times Cassaine has been used as an ordeal poison by African tribes.
 It has also been utilized extensively as an arrow poison by the Casamance people of Senegal.
Solanum physalifolium, known as hoe nightshade, Argentine nightshade, green nightshade and hairy nightshade, is a species in the family Solanaceae (the nightshade family).
 Native to Argentina, Bolivia and Chile, it is widely naturalized in Australia, New Zealand, Europe, western Canada and the north western United States.
 "Solanum physalifolium" has been widely but incorrectly known as "Solanum sarrachoides", a different species.
 It has been listed as a noxious weed in the US states of Kansas and Michigan under this misapplied name.
The genus Alishewanella is one of the major branches of the family Alteromonadaceae.
 It was proposed to accommodate "A. fetalis", isolated from an autopsy of a human fetus, in 2000.
 In 2009, "A. aestuarii" was isolated from tidal flat sediment and indicated as being a representative of Alishewanella.
 The third Alishewanella species was isolated from gajami sikhae, a Korean fermented food, in 2009 and was given the name "A. jeotgali".
 Most recently, in 2010, the fourth currently isolated species of Alishewanella, "A. agri", was isolated from landfill soil in Korea.
 Currently these are the only four isolated and characterized species of the genus Alishewanella.
European black nightshade ("Solanum nigrum") or locally just black nightshade, duscle, garden nightshade, garden huckleberry, hound's berry, petty morel, wonder berry, small-fruited black nightshade, or popolo) is a species in the "Solanum" genus, native to Eurasia and introduced in the Americas, Australasia, and South Africa.
 Parts of this plant can be toxic to livestock and humans.
 Nonetheless, ripe berries and cooked leaves of edible strains are used as food in some locales, and plant parts are used as a traditional medicine.
 A tendency exists in literature to incorrectly refer to many of the other "black nightshade" species as ""Solanum nigrum"".

Question: what is the name of the poison isolated from Duscle garden nightshade?
Answer: Solanine
