Abstrakt: Rat and bovine brain homogenates have been incubated with [4-14C] testosterone under standard conditions. With use of paper chromatography, the extracted metabolites were noted to fall into less polar, iso-polar, and more polar fractions. The components of the iso-polar fraction were separated after acetylation by thin-layer chromatography and the major end-product identified by gas-liquid chromatography and recrystallization to constant specific activity.Rat brain forms a major iso-polar metabolite, allo-tetrahydrotestosterone, and a small amount of tetrahydrotestosterone. Neither of these could be detected in the bovine brain incubates.
