Biosynthesis of bakuchiol from cinnamic and p-coumaric acids

Phytochemistry, 1984
Abstract Specific incorporation of l -[U-14C]phenylalanine, [U-14C]cinnamic acid and p[2-14C]coumaric acid into bakuchiol has been observed in Psoralea corylifolia. Our findings show that the aromatic moiety along with two carbon atoms of the side chain are biosynthetically derived via phenylpropane pathway and not by the alternate pathway proposed ...

Geranyl derivatives of p-coumaric acid from Chrysothamnus pulchellus

Phytochemistry, 1990
Abstract Several E- and Z-configurated cinnamic acid derivatives, all being substituted with a geranyl group, were isolated from the aerial parts of Chrysothamnus pulchellus. The structures were elucidated by high field NMR spectroscopy. The chemotaxonomy of the genus was discussed briefly.

Photo-Fenton-assisted ozonation of p-Coumaric acid in aqueous solution

Chemosphere, 2005
The degradation of p-Coumaric acid present in olive oil mill wastewater was investigated as a pretreatment stage to obtain more easily biodegradable molecules, with lower toxicity that facilitates subsequent anaerobic digestion. Thus, photo-Fenton-assisted ozonation has been studied and compared with ozonation at alkaline pH and conventional single ...

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 ...

New Approaches and Advancements in Drug Development from Phenolic P-coumaric Acid

Current Topics in Medicinal Chemistry, 2022
Abstract: P-coumaric acid is a common dietary polyphenol present in fruits, vegetables, and cereals in conjugated and free form. The toxicity profile of the drug is very low, and it exhibits many pharmacological actions (antihypertensive, anti-inflammatory, anticancer, antimicrobial activity, antidiabetic, anticancer, and antioxidant effect).
