Digitonin is a glycoside obtained from Digitalis purpurea; the aglycone is digitogenin, a spirostan steroid. Used as a detergent, it effectively water-solubilizes lipids. As such, it has several membrane-related applications in biochemistry, including solubilizing membrane proteins, precipitating cholesterol, and permeabilizing cell membranes.

Digitonin is sometimes confused with the cardiac drug digoxin (sometimes also called digitalis or digitoxin), but has no heart-related effects.
