Synthesis of glyceryl ferulate by immobilized ferulic acid esterase
Biotechnology Letters, 2008Glyceryl ferulate was synthesized by the condensation of ferulic acid with glycerol using Pectinase PL "Amano" from Aspergillus niger, which contained ferulic acid esterase, to improve the water-solubility of ferulic acid. The optimum reaction medium was glycerol/0.1 M acetate buffer, pH 4.0, (98:2 v/v).

Metabolism of ferulic acid in rats
Journal of Asian Natural Products Research, 2005Ferulic acid is the major active constituent in many natural Chinese medicinal herbs. The metabolism of ferulic acid has been investigated using solid-phase extraction and HPLC-DAD methods that were established to separate and analyze the metabolites in urine, feces and bile.

Ferulic Acid: Signaling Pathways in Aging
Drug Research, 2023AbstractThe need for clinical remedies to the multiple age-related deficiencies in skin function brought on by extrinsic and intrinsic causes is increased by these demographic changes. Reactive oxygen species (ROS), mitochondrial deoxyribonucleic acid (mtDNA) mutations, telomere shortening, as

Oxidation of Ferulic Acid or Arabinose-Esterified Ferulic Acid by Wheat Germ Peroxidase
Journal of Agricultural and Food Chemistry, 2002The oxidation of ferulic acid (FA) or 5-O-(trans-feruloyl)-L-arabinose (EFA) by a purified wheat germ peroxidase was followed by UV spectrophotometry and high-performance liquid chromatography using an electrochemical detection. Wheat peroxidase (POD) exhibits a ping-pong bireactant mechanism forming phenoxy radicals more rapidly from FA than from EFA ...

Ferulic acid: Pharmacological and toxicological aspects
Food and Chemical Toxicology, 2014Ferulic acid (FA) belongs to the family of phenolic acids and is very abundant in fruits and vegetables. Over the past years, several studies have shown that FA acts as a potent antioxidant by scavenging free radicals and enhancing the cell stress response through the up-regulation of cytoprotective systems, e.g. heme oxygenase-1, heat shock protein 70,

Detoxification of ferulic acid by ectomycorrhizal fungi
Mycorrhiza, 2003The ectomycorrhizal fungi Laccaria amethystina and Lactarius deterrimus grown in liquid culture were used to study the fate of added ferulic acid. Laccaria amethystina degraded ferulic acid to the major metabolite vanillic acid. The intermediate vanillin was not detected. Lactarius deterrimus showed a completely different detoxification pattern.

Antioxidant potential of ferulic acid
Free Radical Biology and Medicine, 1992Ferulic acid is a ubiquitous plant constituent that arises from the metabolism of phenylalanine and tyrosine. It occurs primarily in seeds and leaves both in its free form and covalently linked to lignin and other biopolymers. Due to its phenolic nucleus and an extended side chain conjugation, it readily forms a resonance stabilized phenoxy radical ...

Characterization of physicochemical properties of ferulic acid
Archives of Pharmacal Research, 2003Ferulic acid (3-methoxy, 4-hydroxy cinnamic acid) is a flavoid component possessing antioxidant property. The compound is currently under development as a new drug candidate for the treatment of the dementia. The objective of this preformulation study was to determine the physicochemical properties of ferulic acid.

The Journal of Nutrition, 2003
Ferulic acid sugar esters, the common form of ferulic acid (FA) in cereals, show a stronger antioxidant potential than FA in vitro. However, there is little information on their metabolism and excretion in vivo. In the present study, we investigated the metabolic derivatives of FA in the plasma, urine and feces of rats administered 70 micro mol/kg body
