Steroids squill

History. For centuries man has recognized that rodent pests destroy his habitat, consume his food, and cause the spread of virulent diseases. Throughout the same centuries man has sought to eliminate these pests with a variety of poisons such as strychnine, arsenious oxide, and red squill - a steroidal glycoside extracted from the bulb of a lily-like plant, Urginea maritima. 

An immunogen for proscillaridin, a squill glycoside, can be prepared in the same way as that for ouabain, and the specificity is almost exclusively directed toward proscillaridin and closely related derivatives. Digoxin, digitoxin, and ouabain have only weak cross reactivity whilst steroids are totally ineffective as inhibiting antigens (Belz et al. 1973).
