Digitalis purpurea
(gcide) | Foxglove \Fox"glove`\, n. [AS. foxes-gl[=o]fa,
foxes-cl[=o]fa,foxes-clife.] (Bot.)
Any plant of the genus Digitalis. The common English
foxglove (Digitalis purpurea) is a handsome perennial or
biennial plant, whose leaves are used as a powerful medicine,
both as a sedative and diuretic. See Digitalis.
[1913 Webster]
Pan through the pastures oftentimes hath run
To pluck the speckled foxgloves from their stem. --W.
Browne.

Digitalis purpurea
(gcide) | 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.

(according to Linn[ae]us) from its finger-shaped corolla.]
1. (Bot.) A genus of plants of the family
Schrophulariaceae, including the foxglove.
[1913 Webster]
2. (Med.) The dried leaves of the purple foxglove ({Digitalis
purpurea}), formerly used in heart disease, disturbance of
the circulation, etc. Its use has been largely replaced by
that of the pure active ingredient, digitalin. See

Digitalis purpurea
(gcide) | 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

3-substituted triglucoside of a steroid, related structurally

(gcide) | fingerroot \fingerroot\ n.
