We have already reported (Bray, Ryman & Thorpe, 1947) upon the fate ofp-hydroxybenzoic acid and its amide in the rabbit. The present paper gives the corresponding results for the oand m-isomers. The changes which these compounds might undergo are theoretically the same as those for the p-isomer, i.e. the hydroxyl group may be conjugated with either glucuronic or sulphuric acids and the carboxyl...

AIMS To determine the effect of several wine-associated, phenolic acids on the growth and viability of strains of Oenococcus oeni and Lactobacillus hilgardii. METHODS AND RESULTS Growth was monitored in ethanol-containing medium supplemented with varying concentrations of hydroxybenzoic acids (p-hydroxybenzoic, protocatechuic, gallic, vanillic and syringic acids) and hydroxycinnamic acids (p-...

The phytochemical investigation on the chloroform and ethyl acetate soluble fractions of Colebrookia oppositifolia Smith. led to the isolation of four new-source compounds namely 1pentacosanol (1), stigmast-7-ene-3β-ol (2), p-hydroxybenzoic acid (3), ursolic acid (4) and seven known compounds namely triacontane (5), triacontanol (6), betulonic acid (7), negletein (8), 5,2′,6′-trihydroxy-7-metho...
