a group of glycosides widely distributed in the plant world and characterized by (1) their property of forming durable foam when their watery solutions are shaken; this property may have importance in some plants in the development of frothy bloat in ruminants; (2) their ability to lyse erythrocytes even in high dilutions; and (3) their having the compound sapogenin as their aglycones.

lithogenic s's
saponins in panicoid grasses (Panicum, Brachiaria) Agave lecheguilla, Narthecium ossifragum, Tribulus terrestris are probably responsible for causing crystal-associated cholangiohepatopathy and subsequent secondary photosensitization; this is suspected as the cause of photosensitization associated with other plants. Called also steroidal saponin.
