Bioconversions of Ferulic Acid, an Hydroxycinnamic Acid

Critical Reviews in Microbiology, 2006
Ferulic acid is the most abundant hydroxycinnamic acid in the plant world and is ester linked to arabinose, in various plant polysaccharides such as arabinoxylans and pectins. It is a precursor to vanillin, one of the most important aromatic flavor compound used in foods, beverages, pharmaceuticals, and perfumes.

Antioxidant Potential of Hydroxycinnamic Acid Glycoside Esters

Journal of Agricultural and Food Chemistry, 2008
Hydroxycinnamic acids are natural antioxidants found in fruits, vegetables, and cereals. In this study, the antioxidant activity of various types of hydroxycinnamoyl glycoside esters that mimic the structure of polymeric carbohydrates was studied in different model systems prone to oxidation, namely, liposomes and emulsions.

Anti-inflammatory effects of hydroxycinnamic acid derivatives

Biochemical and Biophysical Research Communications, 2007
NF-kappaB family of transcription factors are involved in numerous cellular processes, including differentiation, proliferation, and inflammation. It was reported that hydroxycinnamic acid derivatives (HADs) are inhibitors of NF-kappaB activation. Rice bran oil contains a lot of phytosteryl ferulates, one of HADs.

Hydroxycinnamic acids and human health: recent advances

Journal of the Science of Food and Agriculture, 2019
AbstractThere is an urgent need to improve human diet globally. Compelling evidence gathered over the past several decades suggests that a suboptimal diet is associated with many chronic diseases and may be responsible for more deaths than any other risks worldwide.

ANODIC OXIDATION OF 4-HYDROXYCINNAMIC ACIDS

Chemistry Letters, 1979
Abstract Anodic oxidation of 4-hydroxycinnamic acids was carried out at a controlled potential vs. SCE (+900 or 840 mV), using an undivided cell, to afford the corresponding asatone or isoasatone-type compound as well as pinoresinol-type dilactones.

Hydroxycinnamic acid esters from broccoli florets

Phytochemistry, 1997
Four conjugates of gentiobiose were isolated, from fresh, raw broccoli florets, using mild extraction conditions and preparative HPLC. From spectroscopic evidence the structures were characterized as two novel conjugates of gentiobiose: 1,2′-disinapoyl-2-feruloygentiobiose and 1-sinapoyl-2-feruloylgentiobiose and, two compounds previously reported to ...

Oxidation of caffeic acid and related hydroxycinnamic acids

Journal of Electroanalytical Chemistry, 1996
Abstract Oxidation of caffeic acid (3,4-dihydroxycinnamic acid) 1H3 has been studied by electrochemical methods and by pulse radiolysis in aqueous and organic solvents. The results have been compared with the behaviour of 4-coumaric acid 2H2 and ferulic acid 3H2.

Antibacterial Activity of Selected Hydroxycinnamic Acids

Journal of Food Science, 1983
ABSTRACT The objective of this study was to determine the antibacterial effectiveness of selected hydroxycinnamic acids (caffeic, ferulic, pcoumaric) against Escherichia coli and Staphylococcus aureus at pH 5.0, 6.0 and 7.0 and

Hydroxycinnamic acid esters from Polygala chamaebuxus

Phytochemistry, 1985
Abstract Three new glycosides have been isolated from the aerial parts of Polygala chamaebuxus by preparative liquid chromatography on an axially-compressed silica column. The compounds were identified as 1,3-diesters of β- D -fructofuranosyl-α- D -glucopyranoside with sinapoyl, feruloyl and acetyl ester moieties on the furanose ring.

Poly(p‐hydroxycinnamic acid)

Die Makromolekulare Chemie, 1985
AbstractPoly(p‐hydroxycinnamic acid) was synthesized by thionyl chloride activated polycondensation of p‐hydroxycinnamic acid at ambient temperatures and by polycondensation of its various monomeric esters at elevated temperatures. The thionyl chloride activated polycondensation proceeds as a 2‐stage process, yielding reduced viscosities of up to 102 ...
