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.

Biosynthesis of bakuchiol from cinnamic and p-coumaric acids
Phytochemistry, 1984Abstract 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 ...

Metabolism of p-coumaric acid during lignification of a bamboo
Phytochemistry, 1970Abstract Occurrence of cinnamic acid-4-hydroxylase in the shoot of bamboos, asparagus, gingko and in seedlings of Japanese cedar was found by using their sliced tissues. Cell-free extraction of the hydroxylase was tentatively achieved with asparagus shoot.

p-Coumaric acid derivatives from Artemisia monosperma
Phytochemistry, 1990Abstract 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 ...

Identification of QTLs associated with p-coumaric acid and ferulic acid in barley
Euphytica, 2019Phenolic acids in plants is receiving more attention because of their nutritive function and essential roles in plant growth. However, the genetics of phenolic acids in barley is still unclear. In this study, two main phenolic acids, i.e. ferulic acid (FA) and p-coumaric acid (p-CA), were analyzed in the grains of a double haploid population derived ...

Degradation of trans-ferulic and p-coumaric acid byAcinetobacter calcoaceticus DSM 586
Biochimica et Biophysica Acta (BBA) - General Subjects, 1995Cell suspensions of Acinetobacter calcoaceticus strain DSM 586 and DSM 590 were able to grow on benzoic, p-hydroxybenzoic and vanillic acid as sole carbon source. Testing the utilization of trans-ferulic and p-coumaric acid, we found that the sole A. calcoaceticus DSM 586 efficiently degraded the lignocellulose related monomers.

Metabolomics has been widely used to identify changes in relevant differential metabolites. The metabolites of Saccharomyces cerevisiae cells supplemented with ferulic acid and p-coumaric acid were prepared and extracted. Untargeted metabolomics analysis of saccharomyces cerevisiae metabolites was performed.

Content of P‐coumaric and ferulic acid in forbs with potential grazing utilization
Archiv für Tierernaehrung, 1999Content of p-coumaric (PCA) and ferulic (FA) acid was determined by the HPLC method in fourteen forbs with a potential utilization as forages (range of nutrient content per kg DM: 100 to 244 g CP, 339 to 528 g NDF and 180-369 g ADF. PCA and FA were determined after methanol extraction in four fractions: free phenolic acids extracted into either, ester ...

Photo-Fenton-assisted ozonation of p-Coumaric acid in aqueous solution
Chemosphere, 2005The 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 ...

The applicability of p-coumaric acid and ferulic acid concentrations or ratios in (sub)fossil plant remnant as UV-B proxies relies on various aspects, which are discussed in this paper and will be illustrated with some experimental data. A newly developed THM-micropyrolysis-gas chromatography-mass spectrometry method was tested on various spores ...
