Medical Definition of Saponins
1. Sapogenin glycosides. A type of glycoside widely distributed in plants. Each consists of a sapogenin as the aglycon moiety, and a sugar. The sapogenin may be a steroid or a triterpene and the sugar may be glucose, galactose, a pentose, or a methylpentose. Sapogenins are poisonous towards the lower forms of life and are powerful haemolytics when injected into the blood stream able to dissolve red blood cells at even extreme dilutions. (12 Dec 1998)
