glycoside

glycoside /gly·co·side/ (gli´ko-sīd) any compound containing a carbohydrate molecule (sugar), particularly any such natural product in plants, convertible, by hydrolytic cleavage, into a sugar and a nonsugar component (aglycone), and named specifically for the sugar contained, as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc.

---

cardiac glycoside  any of a group of glycosides occurring in certain plants (e.g., Digitalis, Strophanthus, Urginea ), acting on the contractile force of cardiac muscle; some are used as cardiotonics and antiarrhythmics.

digitalis glycoside  any of a number of cardiotonic and antiarrhythmic glycosides derived from Digitalis purpurea and D. lanata, or any drug chemically and pharmacologically related to these glycosides.

glycoside

any compound containing a carbohydrate moiety (sugar), particularly any such natural product in plants, convertible, by hydrolytic cleavage, into a sugar and a nonsugar component (aglycone), and named specifically after the sugar contained, as glucoside (glucose), pentoside (pentose), fructoside (fructose), etc.
