Antioxidative activity of a novel antioxidant resorcimoline

Free Radical Research
During the synthesis of a known drug, we synthesized a novel compound impromptu, which we have named resorcimoline. This compound exhibited significant antioxidative activity. In this report, we present the concentration-dependent free radical scavenging activity of resorcimoline against various free radical species.

Antioxidant and Photo-antioxidant Activities of Phenylpropanoids

Journal of the Japan Petroleum Institute, 2008
Phenylpropanoids are one of the metabolic products of phenylalanine and tyrosine. The antioxidant and photo- antioxidant activities were studied kinetically and along the metabolic pathway, to investigate the possibility of application to petrochemical products. The metabolites showed only slight photo-antioxidant activities, compared with a commercial

Antioxidant activity of 4-methylcoumarins

Journal of Pharmacy and Pharmacology, 2007
Abstract Polyphenolic coumarins are known to act as antioxidants in biological systems, but it is difficult to distinguish their antioxidant activity from the many other effects they produce in cells. We have determined the radical scavenging capacity of 22 structurally related natural and synthetic 4-methylcoumarins, by measuring their ...

Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

Advanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Antioxidant Activity of Wine Pomace

American Journal of Enology and Viticulture, 1996
Extractable polyphenols and antioxidant activity of white and red grape pomaces were determined. Total extractable polyphenols assayed by the Folin-Ciocalteu method in white grape pomace (6.5%), skins (5.3%), and seeds (9.2%) were higher than those in red grapes: 2.2%, 2.1%, and 2.1%, respectively.
