Obtained by enzymatic hydrolysis of lanatoside A, q.v. Composed of the aglycone digitoxigenin and 3 mols digitoxose, to one of which an acetyl group is attached. Acetyldigitoxin-α differs from acetyldigitoxin-β in the position of the acetyl group. The β-form is obtained either by splitting off the glucose residue from lanatoside A by means of enzymes, or by extraction from the leaves of Digitalis ferruginea L., Scrophulariaceae. The α-form can be obtained from acetyldigitoxin-β by heating in an anhydrous or aq organic solvent at pH 3.5 to 8: Stoll, Kreis, US 2776963 (1957 to Sandoz).
