In the aerial part of the foxglove red contains steroid glycosides (digitonin, digitoxin, gitonin, gitoksin), as well as a number of genuinic glycosides (purpureaglycosides A and B), which during drying and storage turn into the main (secondary) glycosides. The plant also contains choline, a number of organic acids, flavonoids (luteolin), saponins and other compounds. The leaves include ash, macro-and micronutrients (potassium, calcium, magnesium, zinc, selenium, iron and others).
Digitalis isolated from digitalis has long been the only and indispensable drug in the treatment of chronic heart failure.
