Oxidation of Ferulic Acid or Arabinose-Esterified Ferulic Acid by Wheat Germ Peroxidase

Journal of Agricultural and Food Chemistry, 2002
The 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 ...

Esterification of ferulic acid with polyols using a ferulic acid esterase from Aspergillus niger

Biochimica et Biophysica Acta (BBA) - General Subjects, 2006
Commercially available enzyme preparations were screened for enzymes that have a high ability to catalyze direct ester-synthesis of ferulic acid with glycerol. Only a preparation, Pectinase PL "Amano" produced by Aspergillus niger, feruloylated glycerol under the experimental conditions.

Ferulic acid: Pharmacological and toxicological aspects

Food and Chemical Toxicology, 2014
Ferulic 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,

Characterization of physicochemical properties of ferulic acid

Archives of Pharmacal Research, 2003
Ferulic 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.

Detoxification of ferulic acid by ectomycorrhizal fungi

Mycorrhiza, 2003
The 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.

Ferulic Acid and Alzheimer’s Disease: Promises and Pitfalls

Mini-Reviews in Medicinal Chemistry, 2015
Oxidative stress plays an important role in both initiation and progression of neurodegenerative diseases, such as Alzheimer and Parkinson. Therefore, much attention has been paid to antioxidants for developing therapeutic strategies for the neurodegenerative diseases.

Ferulic Acid Sugar Esters Are Recovered in Rat Plasma and Urine Mainly as the Sulfoglucuronide 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

Regioselective Dimerization of Ferulic Acid in a Micellar Solution

Journal of Agricultural and Food Chemistry, 2001
Dehydrodimers of hydroxycinnamates play an important role in the cross-linking of plant cell walls. An aqueous solution of quaternary ammonium salts with a long aliphatic chain is known to spontaneously organize itself into micelles with the ionic part at the outer sphere. It is shown that regioisomeric ferulic acid dehydrodimers can be obtained in one

Nanodispersion of quercetin and ferulic acid

Journal of Vacuum Science & Technology B: Microelectronics and Nanometer Structures Processing, Measurement, and Phenomena, 2009
Using natural compounds such as flavonoids in combination therapy methods in various diseases such as atopic dermatitis and psoriasis are under special consideration. Unfortunately poor solubility of flavonoids is a significant limitation in preparing pharmaceutical dosage forms.
