Phenolic Acids in Experimental Uremia
Archives of Neurology, 1969A PREVIOUS study has evaluated the role of 3,4-dihydroxybenzoic acid (3,4-DHBA) (procatechuic acid) in the genesis of the uremic syndrome. 1 Like its 2,4-dihydroxy isomer (2,4-DHBA) (β-resorcylic acid), 3,4-DHBA hastened paresis, prostration, and death and contributed to cardiac dysfunction in rats in acute renal failure.

Ninety-six samples of flaxseed from eight cultivars grown at four locations in western Canada for three years were used to study the effect of cultivar, location, and growing season on the phenolic acid contents of the seed. Flaxseed contained 8-10 g/kg of total phenolic acids, about 5 g/kg of esterified phenolic acids, and 3-5 g/kg of etherified ...

Phenolic acids and phenolic glycosides of Gaultheria species
Phytochemistry, 1966Abstract Twenty-two species of Gaultheria were examined for phenols and phenolic acids obtained by hydrolysis of ethanolic extracts. Most species yielded p -hydroxybenzoic, o -pyrocatechuic, protocatechuic, gentisic, vanillic, p -coumaric, caffeic and ferulic acids.

A study of the identification and determination of phenols and phenolic acids in urine
Clinica Chimica Acta, 1958Abstract 1. 1. The following reactions have been examined with a view to their application to the identification and determination of phenolic substances in urine-the Folin-Ciocalteu reaction, indophenol pigment formation, the i -nitroso-2-naphthol reaction and the Ehrlich reagent. 2. 2. Procedures, including the use of paper chromatography,

Inhibition by Phenol and Phenolic Acids of Platelet Release Reaction
Thrombosis and Haemostasis, 1973SummaryIt has been postulated that the high phenol and phenolic acids plasmatic levels found in patients with chronic renal failure are contributory factors in the abnormal platelet function described in these patients. This hypothesis was corroborated by “in vitro” studies showing the deleterious effect of these compounds on certain platelet function ...

Boric acid complexes of phenolic acids
Polyhedron, 1991Abstract The complexation between boric acid and the three phenolic carboxylic acids, 3,4-dihydroxybenzoic, caffeic and chlorogenic acids, has been examined spectroscopically and this has established that a 1 : 1 complex is formed in each case. With the first two acids, there is also evidence of a 2 : 1 complex being formed at high acid to B ratios ...

Aqueous micromolar solutions of glutaraldehyde produce a yellow color when treated with 20% phenol in ethanol followed by concentrated sulfuric acid or with phenol in 70% perchloric acid. The absorbance at 482 or 479 nm, respectively, is linearly related to the glutaraldehyde concentration.

Total Phenolics and Phenolic Acids in Plants and Soils
2007During allelopathic investigations of interrelationships among different plant species in their natural sites, special attention is paid to the presence of phenolic acids (PAs) in dominant plants, plant litter and in the soil. They are localized in all plant organs, both as free and in bound forms i.e.
