Solvation of p-Coumaric Acid in Water

The Journal of Physical Chemistry B, 2007
The photoactive yellow protein (PYP) is an important model protein for many (photoactive) signaling proteins. Key steps in the PYP photocycle are the isomerization and protonation of its chromophore, p-coumaric acid (pCA). In the ground state of the protein, this chromophore is in the trans configuration with its phenolic oxygen deprotonated.

p -Coumaric acid esters from Tanacetum longifolium

Phytochemistry, 2003
Two new long chain alkyl p-coumaric acid esters (2-3) along with eicosanyl trans-p-coumarate (1) were isolated from chloroform extract of the roots of Tanacetum longifolium. The structures of new compounds were assigned as 21'-hydroxyheneicosanyl-4-hydroxy-(cis and trans) p-coumarate (2a, 2b) and 27'-hydroxy heptacosanyl-cis-p-coumarate (3) by ...

Electroanalytical Oxidation ofp‐Coumaric Acid

Analytical Letters, 2007
The mechanism of the electrochemical oxidation of p-coumaric acid on a glassy carbon electrode was investigated using cyclic, differential pulse and square wave voltammetry at different pHs. The oxidation of p-coumaric acid is irreversible over the whole pH range.

Tyrosinase inhibitory p‐Coumaric acid from Ginseng leaves

Phytotherapy Research, 1999
By 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.

Biotransformation of p-coumaric acid by Paecilomyces variotii

Letters in Applied Microbiology, 2006
To investigate the biotransformation of p-coumaric acid into p-hydroxybenzoic acid (p-HBA) by Paecilomyces variotii Bainier MTCC 6581.As a result of p-coumaric acid degradation by P. variotii, three phenolic metabolites, p-hydroxybenzaldehyde (p-HBAld), p-HBA and protocatechuic acid were formed. These phenolics were detected using TLC and HPLC.

Caffeic and coumaric acid esters from Calystegia soldanella

Fitoterapia, 2000
Esters 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.

Coumaric acid degradation by electro-Fenton process

Journal of Electroanalytical Chemistry, 2012
Abstract 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.
