| Abstract: | A high performance liquid chromatographic method is described for the rapid, non-destructive separation of a number of physiologically important steroidal estrogens, including the labile catechol estrogens. This procedures uses a "Diol" column and gradient elution to separate in a single run, estrogens ranging from 2-methoxy estrone, one of the least polar C18 steroids, to estriol, one of the most polar. Simpler, isocratic conditions, are provided for the separation of estrogens of similar polarity. A semi-preparative column of similar composition was used for the purification of samples containing 25 to 50 mg of individual steroids. |
