STUDIES CONCERNING THE OBTAINING OF A HIGH-CLASS DIGITALIS LANATA DRUG x
In cardiotherapy, the use of digitalis glycosides, mainly the glycosides C /digoxin and lanatoside C/ of Digitalis lanata, is preferred.
Prerequisite for the low-cost production of glycosides of the series C is the obtaining of a drug with a high and constant content of lanatoside C and content of digoxin, respectively. The high content of lanatoside C has to correlate with a high yield of green mass /about 30 tons/hectare/ and the resistance to fungus attacks.
The Digitalis lanata of different origin which was at our disposal at the beginning of our studies, did not meet these demands /table 1/.
