Steroidal alkaloids found in Solanaceae

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. Solanine was first isolated in 1820 from the berries of the European black nightshade (Solanum nigrum), after which it was named. It belongs to the chemical family of saponins.

α-Chaconine is a steroidal glycoalkaloid that occurs in plants of the family Solanaceae. It is a natural toxicant produced in green potatoes and gives the potato a bitter taste. Tubers produce this glycoalkaloid in response to stress, providing the plant with insecticidal and fungicidal properties. It belongs to the chemical family of saponins. Since it causes physiological effects on individual organism, chaconine is considered to be a defensive allelochemical. Solanine, a related substance also found in potatoes, has similar properties.

Tomatine (sometimes called tomatin or lycopersicin) is a glycoalkaloid, found in the stems and leaves of tomato plants, and in the fruits at much lower concentrations. Chemically pure tomatine is a white crystalline solid at standard temperature and pressure.

Solamargine is a cytotoxic chemical compound that occurs in plants of the family Solanaceae, such as potatoes, tomatoes, and eggplants. It has been also isolated from Solanum nigrum fungal endophyte Aspergillus flavus. It is a glycoalkaloid derived from the steroidal alkaloid solasodine.

Solanidine is a poisonous steroidal alkaloid chemical compound that occurs in plants of the family Solanaceae, such as potato and Solanum americanum. The sugar portion of glycoalkaloids hydrolyses in the body, leaving the solanidine portion. == Occurrence == Solanidine is the hydrolyzed form of several naturally occurring compounds all found in the Solanaceae family, such as glycoalkaloids, α-solanine and α-chaconine. Solanidine is not commonly found in nature, but precursors to it are. Glycoalkaloids are one of the toxins present in Solanum dulcamara and can be found in other Solanum plants

Solasonine is a glycoalkaloid that is found in Solanum plants of the family Solanaceae. Solasonine is a poisonous chemical compound when used at high levels. It is a glycoside of solasodine. Glycoalkaloids such as solasonine have various applications including pharmacology, cancer treatments and even a role as a pesticide.

Solasodine is a poisonous alkaloid chemical compound that occurs in plants of the family Solanaceae such as potatoes and tomatoes. Solasonine and solamargine are glycoalkaloid derivatives of solasodine. Solasodine is teratogenic to hamster fetuses in a dose of 1200 to 1600 mg/kg. A 2013 literature survey found that various studies have indicated that solasodine may have diuretic, anticancer, antifungal, cardiotonic, antispermatogenetic, antiandrogenic, immunomodulatory, antipyretic and/or various other effects on central nervous system.

Solanocapsine is a toxic steroidal alkaloid from Jerusalem cherry (Solanum pseudocapsicum).
