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. It is the largest genus in the nightshade family Solanaceae, comprising around 1,500 species. It also contains the so-called horse nettles, as well as numerous plants cultivated for their ornamental flowers and fruit.
Heinz Ludwig Fraenkel-Conrat was a biochemist, famous for his research on viruses.
Solanum dulcamara is a species of vine in the genus Solanum of the family Solanaceae. Common names include bittersweet, bittersweet nightshade, bitter nightshade, blue bindweed, Amara Dulcis, climbing nightshade, felonwort, fellenwort, felonwood, poisonberry, poisonflower, scarlet berry, snakeberry, trailing bittersweet, trailing nightshade, violet bloom, and woody nightshade.
Solanine is a glycoalkaloid poison found in species of the nightshade family within the genus Solanum, such as the potato. 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, after which it was named. It belongs to the chemical family of saponins.
Solanum pseudocapsicum is a nightshade species with mildly poisonous fruit. It is commonly known as the Jerusalem cherry, Madeira winter cherry, or, ambiguously, "winter cherry". These perennials can be grown decoratively as house plants, but in some areas of South Africa, India, Australia and New Zealand it is regarded as a weed.
Solanum americanum, commonly known as American black nightshade, small-flowered nightshade or glossy nightshade, is a herbaceous flowering plant of wide though uncertain native range. The certain native range encompasses the tropics and subtropics of the Americas, Melanesia, New Guinea, and Australia.
Solanum nigrum, the European black nightshade or simply black nightshade or blackberry nightshade, is a species of flowering plant in the family Solanaceae, native to Eurasia and introduced in the Americas, Australasia, and South Africa. Ripe berries and cooked leaves of edible strains are used as food in some locales, and plant parts are used as a traditional medicine. Some other species may also be referred to as "black nightshade".
Solanum nelsonii, common names pōpolo and Nelson's horsenettle, is a partially woody sprawling shrub-like perennial plant in the family Solanaceae, part of the Solanum or nightshade genus. This poisonous plant is endemic to the Pacific Islands. It grows low in coastal sites in coral rubble to pure sand.
Solanum elaeagnifolium, the silverleaf nightshade or silver-leaved nightshade, is a species of plant in the nightshade family native to North and South America. It is common in parts of southwestern USA, and sometimes weed of western North America. Other common names include prairie berry, silverleaf nettle, white horsenettle or silver nightshade. In South Africa it is known as silver-leaf bitter-apple or satansbos. More ambiguous names include "bull-nettle", "horsenettle" and the Spanish "trompillo".
Heterodera tabacum is a plant pathogenic nematode affecting Jerusalem cherries.
Solanum ternatum is a species of plant in the family Solanaceae. Its natural habitat is subtropical or tropical moist montane forests.
The enzyme polyneuridine-aldehyde esterase (EC 3.1.1.78) catalyzes the following reaction:
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.
Solanum seaforthianum, the Brazilian nightshade, is a flowering evergreen vine of the family Solanaceae native to tropical South America. As a member of the Solanum genus, it is related to such plants as the tomato and potato. It is characterized by clusters of four to seven leaves and can climb to a height of 6 m (20 ft) given enough room. It blooms in the mid to late summer with clusters of star-shaped purple inflorescence followed by scarlet marble-sized berries. The plant is highly heat resistant, but cannot tolerate frost conditions. The plant contains modest amounts of various tropane alkaloids such as atropine, scopolamine and hyoscyamine and should be considered mildly toxic and inedible. Promising molluscicidal and schistosomicidal activities were displayed for the S. seaforthianum extracts and fractions which are attributed to the glycoalkaloid content.
Solanum diphyllum, commonly known as the twoleaf nightshade, is a species of nightshade native to the Americas. It is cultivated as an ornamental plant for its clusters of dark green round fruits that turn a bright yellow when ripe.
Hellinsia surinamensis is a moth of the family Pterophoridae. It is found in Suriname, Argentina, Bolivia, Colombia, Ecuador, Paraguay and Uruguay.
Solanum macrocarpon otherwise known as the African eggplant : añara), Surinamese eggplant or Vietnamese eggplant is a plant of the family Solanaceae. S. macrocarpon is a tropical perennial plant that is closely related to the eggplant. S. macrocarpon originated from West Africa, but is now widely distributed in Central and East Africa. The plant also grows in the Caribbean, South America, and some parts of Southeast Asia. S. macrocarpon is widely cultivated for its use as a food, its medicinal purposes, and as an ornamental plant.
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.
Steroidal alkaloids have the basic steroidal skeleton with nitrogen-based functional groups attached to the skeleton. More specifically, they are distinguished by their tetracyclic cyclopentanoperhydrophenanthrene skeleton that marks their close relationship with sterols. They fall in two major categories: Solanum alkaloids and Veratrum alkaloids. A Steroidal alkaloid has also been found in Chonemorpha fragrans, 'chonemorphine' was used to treat intestinal infections in Wistar rats..
The Solanaceae, 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 agricultural crops, medicinal plants, spices, weeds, and ornamentals. Many members of the family contain potent alkaloids, and some are highly toxic, but many—including tomatoes, potatoes, eggplant, bell, and chili peppers—are used as food. The family belongs to the order Solanales, in the asterid group and class Magnoliopsida (dicotyledons). The Solanaceae consists of about 98 genera and some 2,700 species, with a great diversity of habitats, morphology and ecology.
