Coumaric acid degradation by electro-Fenton process
Journal of Electroanalytical Chemistry, 2012Abstract The degradation of the p-coumaric acid (CA, 4-hydroxycinnamic acid) has been investigated by electro-Fenton process. The electrolyses have been performed using an undivided cell equipped with a Ti/RuO 2 anode and a commercial graphite-felt to electrogenerate in situ hydrogen peroxide and regenerate ferrous ions as catalyst.

Synthesis and properties of coumaric acid derivative homo-polymers
Journal of Biomaterials Science, Polymer Edition, 2008Poly(4-hydroxycinnamic acid) (P4HCA), poly(3-hydroxycinnamic acid) (P3HCA), poly(3-methoxy-4-hydroxycinnamic acid) (PMHCA) and poly(3,4-dihydroxycinnamic acid) (PDHCA) were synthesized by the thermal poly-condensation of the corresponding monomers, which are lignin precursors, coumaric acid derivatives consisting of cinnamoyl groups and different ...

Benefits of p-coumaric acid in mice with rotenone-induced neurodegeneration
Metabolic Brain Disease, 2022The paper examines the use of natural antioxidant and anti-inflammation substances as therapeutic candidates for brain disease. Para-coumaric acid (pCA), a phenolic compound with a variety of medicinal properties, was used against deterioration caused by various diseases.

Caffeic and coumaric acid esters from Calystegia soldanella
Fitoterapia, 2000Esters of trans-4-hydroxycinnamic acid, cis-4-hydroxycinnamic acid and trans-3,4-dihydroxycinnamic acid with long-chain alcohols (n=15-20), were isolated from the stems of Calystegia soldanella.

Tyrosinase inhibitory p‐Coumaric acid from Ginseng leaves
Phytotherapy Research, 1999By bioassay-guided fractionation using mushroom tyrosinase, p-coumaric acid was characterized as the principal tyrosinase inhibitor from the fresh leaves of Panax ginseng (Araliaceae). It inhibited the oxidation of L-tyrosine more strongly than that of L-3, 4-dihydroxyphenylalanine (L-DOPA) by this enzyme.

A spectrophotometric study of the ionization of p-coumaric acid
Spectrochimica Acta, 1965Abstract A spectrophotometric study of the ionized and un-ionized forms of the cis and trans stereoisomerides of p-coumaric acid in ethanol and water solution has been made. The complex spectra were interpreted by calculation of the corresponding incremental second derivative functions.

Fluorometric determination of p-coumaric acid in beer
Journal of Agricultural and Food Chemistry, 1988A new spectrofluorometric method to determine p-coumaric acid in beer has been developed. After the pH of the samples was adjusted to 2, impurities were extracted into hexane. Phenolics were then extracted into ethyl acetate, dried, and redissolved in water.

Synthesis and Antifungal Activity of Anilides of Salicylic Acid and o-Coumaric Acid
Journal of Pharmaceutical Sciences, 1963Abstract A series of o -hydroxycinnamanilides and the corresponding series of salicylanilide derivatives were prepared and tested for antifungal activity. These compounds were investigated for the purpose of determining the effect of vinylogy and also the effect of substitution on the anilide rings.
