Conformational Map of Phenolic Acids
The Journal of Physical Chemistry A, 2018The benefits of vaporization by laser ablation and the high resolution and sensitivity attained by the chirped pulse Fourier transform microwave spectroscopy CP-FTMW have provided the first conformational map of the simplest phenolic acids of trans-cinnamic and p-coumaric.

Phenolic acids in oilseed flours
Food / Nahrung, 1983AbstractNoticeable quantitative differences were found in the content of free and bound phenolic acids in flours obtained from soybeans, cottonseed, peanuts, rapeseed, white mustard, flax and sesame seeds. Independently of the type of seeds used to produce flour, the highest amounts of acids were liberated from ester bonds.

Phenol electropolymerization in acid medium
Makromolekulare Chemie. Macromolecular Symposia, 1987AbstractAn overview is given of phenol electro‐polymerization in oxalic acid media, as a method of corrosion protection for Fe substrates. The work focuses on the electrical and/or chemical parameters of the system which mainly determine the growth and/or corrosion resistance of the organic‐inorganic films thus obtained.

Potentiometric titration of phenols with sodium methoxide in dimethylformamide, with a glass-calomel electrode system, is limited to monohydric phenols substituted with electron-attracting groups and dihydric phenols in which the two -OH groups are substituted in isolated benzene rings.

Simple phenols (catechol, 4-methyl catechol, resorcinol, phloroglucinol and pyrogallol), phenolic acids (p-hydroxybenzoic acid, protocatechuic acid, vanillic acid, gallic acid, syringic acid and salicylic acid), a phenylacetic acid (3,4-dihydroxyphenylacetic acid) and eugenol were assayed for clastogenic activity in Chinese hamster ovary (CHO) cells ...

Abstract Six phenolic acids were found in leaves of over 50% of the seagrasses surveyed. p -Hydroxybenzoic acid was the most ubiquitous and was recorded in each of the 12 genera and in each of the 25 species that included both Gulf-Caribbean and Indo-Pacific seagrasses.

Journal of Agricultural and Food Chemistry, 1995
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 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.

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.
