A new method for the simultaneous determination of cortisol and cortisone in serum by high-performance liquid chromatography with fluorimetric detection has been developed. The two steroids were derivatized by treatment with 9-anthroyl nitrile in triethylamine-acetonitrile to give the fluorescent es
