Insights into the antioxidant activity of some flavones on silver nanoparticles using the chemiluminescence method

The work aims to simulate in vitro the effects caused by oxidation of five hydroxyflavones (HF) (some typical models of flavonols), (3-HF, 6-HF, 7-HF, 3,6-diHF and 3,7-diHF) on silver nanoparticles (SNPs) using the chemiluminescent system luminol-hydrogen peroxide, in phosphate buffer, pH 7.4. The contribution of bovine and human serum albumins to the antioxidant activity of the mentioned flavones, and the effect on the SNPs support, in the chemiluminescent system luminol-hydrogen peroxide, has been also investigated. The results are discussed with relevance to the oxidative stress process.
