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.

Efficiency of Trapping Methylglyoxal by Phenols and Phenolic Acids
Journal of Food Science, 2011Abstract: The carbonyl stress that leads to the formation of advanced glycation end products (AGEs) has drawn much attention recently because of its micro‐ and macrovascular implications. During monitoring of methylglyoxal (MG), the efficiency of phenolics to directly trap MG can be demonstrated.

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 ...

Aquatic Botany, 1979
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 ...

AbstractBACKGROUNDPhenolic acid exhibits a variety of well‐known physiological functions. In this study, optimal germination conditions to ensure total phenolic acid enrichment in barley sprouts induced by salicylic acid treatment and its effects on sprout physiology and activity, as well as the gene expression of key enzymes for phenolic acid ...

Oxidative phenol-arene and phenol-phenol cross-coupling using periodic acid
Tetrahedron, 2019Abstract A simple, metal-free protocol for unsymmetrical biaryl coupling using H5IO6 is reported. H5IO6 was evaluated for a novel application in the oxidative cross-coupling of phenol-arene, phenol-phenol, and phenol-naphthol compounds. In this work, most of the couplings were completed within 30 min at ambient temperature.

Shikimic Acid Pathway: Phenols
2023Plant metabolites having one or more hydroxyl groups attached to an aromatic ring are known as phenols. Phenols are a heterogeneous group of compounds. One of the most important functions of phenols is in plant communication e.g., allelopathy, attracting pollinating and disseminating agents, attracting symbiotic bacteria, and inhibiting pathogens and ...
