Definition: Digitalis lanata
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.

digitoxin
\dig`i*tox"in\ (d[i^]j`[i^]*t[o^]k"s[i^]n), n. (Chem.)
A steroid glycoside, one of the cardiotonic chemical
substances which is extracted from the foxglove. It is a
white, crystalline substance (
C41H64O13), and is a
3-substituted triglucoside of a steroid, related structurally
to digitalin and digoxin. It is used as a cardiotonic for
treatment of certain heart conditions, such as congestive
heart failure. Chemically it is
(3[beta],5[beta])-3-[(O-2,6-Dideoxy-[beta]-D-ribo-hexopyranosyl-(1[rarr]4)-O-2,6-dideoxy-[beta]-D-ribo-hexopyranosyl-(1[rarr]4)-2,
6-dideoxy-[beta]-D-ribo-hexopyranosyl)oxy]-14-hydroxy-card-20(22)-enolide.
The related compounds
digitalin and
digoxin are also
extracted from the foxglove (
Digitalis lanata and
Digitalis purpurea). The class of steroid glycosides having
cardiotonic properties are refered to as the cardiac
glycoside group. --MI11
