Analysis of corticosteroids in human adrenal tissue by high pressure liquid chromatography.

High pressure liquid chromatography (HPLC) was demonstrated to be a good tool for the separation, identification and quantitation of corticosteroids (CS) extracted from homogenized tissue of adrenal glands and adrenal tumors in patients with hypercorticism. A chromatographic system consisting of Sorbax-SIL and Sorbax-CN columns, organic solvent extraction and a UV detector was used to analyze both more polar and less polar corticosteroids in the adrenal tissue.
