  digitalin \dig"i*ta`lin\, n. [Cf. F. digitaline.]
        (a) (Medicine, Pharmacy) Any one of several extracts of
            foxglove ({Digitalis}), as the "French extract," the
            "German extract," etc., which differ among themselves
            in composition and properties. Both {Digitalis lanata}
            and {Digitalis purpurea} have been used to prepare


            such extracts.
        (b) (Chem.) the distinctive chemical substance, a steroid
            glycoside, which is the essential ingredient of the
            extracts of foxglove. It is a white, crystalline
            substance ({C36H56O14}), and is a 3-substituted
            diglucoside of a steroid. It is a powerful cardiac
            stimulant and is used as a cardiotonic for treatment
            of certain heart conditions, such as congestive heart
            failure. Chemically it is
  
            (3[beta],5[beta],16[beta])-3-[6-Deoxy-4-O-[beta]-D-glucopyranosyl-3-O-methyl-[beta]-D-galactopyranosyl)oxy]-14,16-dihyroxy-card-20
            (22)-enolide. The related compounds {digitoxin} and
            {digoxin} are also extracted from the foxglove. The
            class of steroid glycosides having cardiotonic
            properties are refered to as the cardiac glycosides.
