The corticoid was extracted with chloroform from the rat adrenals and this solution was then passed through a small column of florisil. The eluates were evaporated to dryness, then the dry residue was dissolved in chloroform and was deposited on to the plates which was coated with silica gel. The solvent systems were chloroform-aceton (3: 2), and ascending chromatography was carried out. The Rf values of aldosterone, 18-hydroxycorticosterone and corticosterone in the systems were respectively 0.33, 0.18 and 0.56, and over-all recovery throughout the separation steps was 75 per cent. These corticoids have been thus separated by thin layer chromatography and the method is available for the study of adrenal activity, especially in the rat.
