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.

p-Coumaric acid abatement by ozone in aqueous solution
Water Research, 1995Abstract The ozonation process of p-coumaric acid in aqueous solution is studied by identification and quantitative evaluation of intermediates and final oxidation products. In all the investigated pH range (2.0–8.0) the initial oxidation step is represented by the direct attack of ozone to the exocyclic double bond, following oxidation steps being ...

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.

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.
