solanine

[′sō·lə‚nēn]
(biochemistry)
A bitter poisonous alkaloid derived from potato sprouts (Solanum tuberosum), tomatoes, and nightshade.

Solanine

 

any one of several plant glycosidal alkaloids in which the steroidal alkaloid solanidine is the aglycon. The carbohydrate portion consists of one to three monosaccharides (glucose, galactose, and rhamnose). Solanines occur in plants of the genus Solarium of the family Solanaceae; especially high concentrations are present in the shoot tips and flowers of the potato. The compounds have a bitter taste and, together with other alkaloids, apparently deter animals from eating the plants.
