Abstract A luminol chemiluminescence (CL) reaction was applied for the simultaneous determination of nine corticosteroids (triamcinolone, prednisolone, prednisone, cortisone, betamethasone, dexamethasone, corticosterone, flumethasone and triamcinolone acetonide) using flow injection. The luminol solution was prepared in NaOH with hexacyanoferrate(II) and hexacyanoferrate(III) was used as oxidant. Adequate isocratic chromatographic separation was obtained using a simple mobile phase (acetonitrile...

A method for the determination of nine corticosteroids in bovine liver was developed. The liquid–liquid extraction method consisted in the addition of sodium hydroxide to the tissue sample followed by extraction with ethyl acetate. After centrifugation, the extract was evaporated to dryness and the residue redissolved in acetonitrile. The removal of fats was performed with n-hexane and the acetonitrile layer was evaporated. Afterwards, analysis of the extracts was performed using high-performanc...

A new method for the determination of dexamethasone (9α-fluoro-11β,17α,21-trihydroxy-16α-methylpregna-1,4-diene-3,20-dione) in bovine liver was developed. This new liquid−liquid extraction method comprises the addition of sodium hydroxide to the tissue sample followed by extraction with ethyl acetate. After centrifugation, the extract is evaporated to dryness and the residue dissolved in acetonitrile. The cleaning of the fat is performed with n-hexane, and the acetonitrile layer is evaporated. A...
