title: A comparison of three methods of hydrolysis for estrogen conjugates.
abstract: The efficiencies for estrogen conjugate hydrolysis were compared between enzyme hydrolysis, acid solvolysis and a new method, ammonolysis. Samples included: 1) crystalline 1,3,5(10)-estratriene-3, 17 beta-diol disulfate (estradiol 3,17-disulfate), 2) squirrel monkey urine collected following an intravenous injection of [2,4,6,7-H] 1,3,5(10)-estratriene-3,17 beta-diol (estradiol) and 3) a pool of human pregnancy urine. Ammonolysis demonstrated a significant increase over the other techniques in "free" estrogen yields, specifically, from estradiol 3,17-disulfate.
