Abstract

IN 1937, Hirschmann and Wintersteiner1 reported the isolation of 17-dihydroequilenin from the urine of pregnant mares and expressed surprise that no evidence of the presence of dihydroequilin was obtained. (The nomenclature used here is that employed by Carol and his co-workers3,4,6.) Afterwards, the presence of β-dihydroequilin was detected in material derived from pregnant mares' urine by the dioxane hydrolysis procedure of Grant and Beall2, but isolation was not effected3.
