title: A high-pressure-liquid-chromatography method for the determination of corticosterone in rat plasma.
abstract: A high-pressure-liquid-chromatography (HPLC), isotope dilution method for the determination of corticosterone in rat plasma is reported. Main characteristics of the technique are: efficient separation of the steroid from 18-HO-DOC and 11-deoxycortisol; two easy pre-purification steps consisting of an acetone extraction-deproteinization and fractionation on Sephadex LH-20; a sensitivity of 5 ng per injection and the possibility of determining 25 ng corticosterone in approximately one milliliter rat plasma.
