THE IDENTIFICATION OF SOME ADRENOCORTICAL STEROIDS IN URINE

 N. J. HOLNESS, J. BARBARA LUNNON and C. H. GRAY

The two {alpha}-ketolic steroids R3 and R4, previously described by de Courcy, Bush, Gray & Lunnon [1953], and which lack the {Delta}4-3-keto group, have been identified as tetrahydrocortisol (5β-pregnane-3{alpha}:11β:17{alpha}:21-tetrol-20-one) and tetrahydrocortisone (5β-pregnane-3{alpha}:17{alpha}:21-triol-11:20 dione). The {Delta}4-3-ketone, X3, is shown to be identical with Reichstein's compound E ({Delta}4-pregnene-11β:17{alpha}:20β21-tetrol-3-one). X4 has chromatographic properties resembling Reichstein's compound U ({Delta}4-pregnene-17{alpha}:20β:21-triol-3:11-dione).
