Salicylic Acids

Vanillic and salicylic acids, and the coumarins marmesin, herniarin, esculetin, and bergapten were identified as constituents of whole tomato plants by paper and thin-layer chromatography and ultraviolet spectroscopy in the presence of diagnostic reagents. Strong evidence for the occurrence of p-hydroxybenzoic, syringic, ferulic, and p-hydroxycinnamic acids was obtained on the basis of chromatographic data and chromogenic reactions. Only the last two compounds and salicylic acid had been reported to occur in tomato plants. Biosynthetic implications of the occurrence of these phenolics are considered.

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.
