Abstract

Female sexual hormones are obtained from the urine of stallions by heating the slightly acidified urine, cooling and extracting with an organic solvent e.g. ether, washing the extract with sodium carbonate solution and then with water, evaporating the solvent and purifying the extract in the usual manner. Reference has been directed by the Comptroller to Specification 392,039.
