Abstract
A thin-layer chromatographic method for the determination of hydrocortisone in powdered preparations after the treatment of hydrocortisone with sulfuric acid is described. After developing with chloroform/methanol (85: 15 v/v), silica gel plates were dried, sprayed with sulfuric acid solution, and heated. Hydrocortisone spot on the chromatogram was measured with a TLC densitometer equipped with a dual-wave length TLC scanner at λEx 380nm, AEM 550nm.
