p-Coumaric acid attenuates alcohol exposed hepatic injury through MAPKs, apoptosis and Nrf2 signaling in experimental models.

Chemico-Biological Interactions, 2020
Overconsumption of alcohol could lead to severe liver injury that connects with oxidative stress, apoptosis, and inflammatory response. Previously, we proved that p-coumaric acid prevents ethanol induced reproductive toxicity; however, p-coumaric acid ...

Coumaric acid derivatives as tyrosinase inhibitors: Efficacy studies through in silico, in vitro and ex vivo approaches.

Bioorganic chemistry (Print), 2020
p-Coumaric acid is a known inhibitor of tyrosinase, an enzyme involved in the initial steps of the melanin synthesis in human and other species. However, its low lipophilicity impairs its penetration through skin and efficacy as antimelanogenic agent ...

Production of coumaric acid from sugarcane bagasse

Innovative Food Science & Emerging Technologies, 2009
Abstract Phenolic acids were released from sugarcane bagasse by alkaline hydrolysis at 30 °C for 4 h; The alkaline hydrolysates were ultrafiltrated, the permeates purified with anion exchange resin. The phenolic acids bound by the resin were desorbed by a mixture of water–ethanol–HCl solution (36: 60: 4) after washing the resin with water, ethanol ...

Defense Responses, Induced by p-Coumaric Acid and Methyl p-Coumarate, of Jujube ( Ziziphus jujuba Mill.) Fruit against Black Spot Rot Caused by Alternaria alternata.

Journal of Agricultural and Food Chemistry, 2019
The esterified fraction of jujube ( Ziziphus jujuba Mill.) peel extract showed strong antifungal activity on Alternaria alternata. p-Coumaric acid (pCA) was found to be the most predominant individual phenolic acid that was correlated highly with the ...

Goitrogenic activity of p‐coumaric acid in rats

Journal of Biochemical and Molecular Toxicology, 2003
AbstractThe effects of three natural phenolic acids (caffeic, ferulic, and p‐coumaric) on the rat thyroid gland were examined in a 3‐week oral‐treatment study. Forty male Wistar albino rats, divided into groups of 10 rats each and fed iodine‐rich diet, were administered by gastrointestinal tube saline (control), caffeic acid, ferulic acid, or p ...

p-Coumaric acid derivatives from Artemisia monosperma

Phytochemistry, 1990
Abstract Artemisia monosperma afforded four flavonoids, two acetylenes, eight p -hydroxyacetophenone derivatives and three p -coumaric acid derivatives, two of them being new. The structures were elucidated by spectral methods. The flavonoids present are naringenin 7-methyl ether, eriodictyol 7-methyl ether, quercetin 3,7-dimethyl ether and ...

Application of p-coumaric acid for extraordinary lipid production in Tetradesmus obliquus: A sustainable approach towards enhanced biodiesel production

, 2020
In the present study, biomass and lipid production of the biodiesel promising green microalga Tetradesmus obliquus BPL16 were studied by application of p-coumaric acid as a suggested novel growth regulator found predominantly in phenolics-rich streams ...
