Gas liquid and thin layer chromatography have been combined into a single microphysicochemical technique. The resolution of two terpenoids found in nature—piperitone and piperitone oxide—is described to illustrate the scope of the novel method of analysis. Occurrence of the epoxide in Mentha arvensis (Japanese mint), Mentha piperita (Mitcham peppermint), Eucalyptus dives Schauer, "Type" ("broad-leaved peppermint"), and Eucalyptus numerosa Maiden, var. "A" is reported for the first time. Its presence in these species should prove of biochemical as well as taxonomic interest.

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.
