Abstract

Reversed-phase high-pressure liquid chromatography with gradient elution on Zorbax-ODS columns has been used to separate, identify, and measure, spectrophotometrically, the steroids secreted by both human adrenal and testis cells in primary monolayer culture. Three related systems using exponential concave gradients have been developed with the specific objective of resolving the steroids produced by these two tissues. A methanol-water gradient has been used to separate most adrenal steroids, an acetonitrile-water gradient to separate testis steroids, and a dioxane-water gradient to separate polar steroids, including aldosterone. These three systems together permit the resolution of at least 43 naturally occurring steroids, plus four synthetic steroids with adrenocortical activity, with overall total elution times of 1 h or less for each system. Retention data for these steroids are given and the separation of steroids in the biological samples illustrated.
