A poisonous glucoside found in many plants, as in the root of soapwort (Saponaria), in the bark of soap bark (Quillaia), etc. It is extracted as a white amorphous powder, which occasions a soapy lather in solution, and produces a local anaesthesia. Formerly called also struthiin, quillaiin, senegin, polygalic acid, etc. By extension, any one of a group of related bodies of which saponin proper is the type.

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 hemolytics when injected into the blood stream able to dissolve red blood cells at even extreme dilutions.

The term is used generically for a group of not well-defined glucosidal, non-nitrogenous substances, which are hemolytic and which cause frothing even in very dilute solution, hence the term. The s's are widely distributed; most of them are neutral in reaction, some are acid, and one (solanin) contains nitrogen and acts as a base. In a more restricted sense the term is applied to the saponin obtained from Saponaria officinalis and Quillaja. The formula is probably C17H26O10. Commercial s. consists largely of sapotoxin. See sapotoxin. [Lat.]
