A method was developed for estimating Cortisol metabolites in urine (1) which involved a preliminary separation of the extract by paper chromatography (Bush B5 system) and, after bismuthate oxidation, determination by GLC on a neopentyl glycol adipa

Soil Physical and Moisture Properties,rmal instability of corticosteroids, and their derivatives which have been studied so far, made it seem unlikely that ester derivatives (acetate, formats, 5-dinitrobenzoates) would survive GLC. In view of the results obtained for steroids of the 21,17α-dihydroxy-20-oxo series, by masking the active
