A relatively simple method of gas chromatography, permiting the quantitative estimation of the most important urinary 17-ketosteroids and 17-OH corticosteroids, is reported. The procedure consists in enzyme hydrolysis, dichloromethane extraction, and (without any further purification) gas-liquid chromatography of the steroids as theiro-methyloxime-trimethyl silyi ether (MO-TMS) derivatives. The method is shown to be useful in clinical studies.
