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).

The compounds have a bitter taste and, together with other alkaloids, apparently deter animals from eating the plants.
