The product of enzymatic reduction of phloroglucinol was tentatively identified as a dihydrophloroglucinol based on thin-layer chromatography and ultraviolet spectrum. Confirmatory evidence of its identity is presented by mass spectroscopic analysis.

ABSTRACT Rat and bovine brain have been incubated with testosterone-4-14C 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 less-polar fraction were separated by acetylation and thin-layer chromatography and the major end-products identified by recrystallization to constant specific activity or constant 3H/14C ratios. Androst-4-enedione and 5α-dihydrotestosterone were formed consistently under the conditions utilized. Trace amounts of other less-polar metabolites were noted occasionally.
