Flavonoids are widely occurring polyphenol compounds of plant origin with multiple
biological and chemical activities. Due to the presence of carbonyl and hydroxyl groups they …

Tannins, also known as plant polyphenols (PPs), are secondary metabolites widely existing
in higher plants and are a kind of natural renewable resource with wide distribution, variety …

In this review, primary attention is given to the antioxidant (and prooxidant) activity of
polyphenols arising from their interactions with iron both in vitro and in vivo. In addition, an …

Iron oxide nanoparticles (IONPs) have been proposed as targeted carriers to deliver
therapeutic molecules in the central nervous system (CNS). However, IONPs may damage …

Polyphenols (synthetically modified or directly provided by human diet) scavenge free
radicals by H-atom transfer and may thus decrease noxious effects due to oxidative stress …

The reactions of 10 flavonoids with 2, 2-diphenyl-1-picrylhydrazyl radical (dpph•) carried out
in alcohols always occur significantly faster than in acidified alcohols or in dioxane. These …

Simple sugars and their derivatives—with oxygen, nitrogen, sulphur or phosphorous
anchoring donor groups—form metal ion complexes of various composition and stability …

The benefits of flavonoids on human health are very often ascribed to their potential ability to
act diminishing free radical steady state concentration in biological systems providing …

Despite the intensive research on radical scavenging action of flavonoids, a systematic
study of the thermochemistry for their mono-deprotonated species in aqueous solution is still …

Complex formation between aluminium and quercetin (Q) in methanol was studied by the
combined use of spectroscopic measurements and quantum chemical calculations …
