Journal ArticleDOI
Interactions of Flavonoids with Iron and Copper Ions: A Mechanism for their Antioxidant Activity
Lurdes Mira,M T Fernandez,Marta R. Santos,Rafaella Martins Freitas Rocha,M. H. Florêncio,Keith R. Jennings +5 more
TL;DR: The metal chelating properties of flavonoids suggest that they may play a role in metal-overload diseases and in all oxidative stress conditions involving a transition metal ion.
Journal ArticleDOI
Rosmarinic acid, scutellarein 4′-methyl ether 7-O-glucuronide and (16S)-coleon E are the main compounds responsible for the antiacetylcholinesterase and antioxidant activity in herbal tea of Plectranthus barbatus ("falso boldo").
Pedro L. Falé,Carlos Borges,Paulo J. Amorim Madeira,Lia Ascensão,Maria Eduarda M. Araújo,M. H. Florêncio,Maria Luísa Serralheiro +6 more
TL;DR: Plectranthus barbatus, known as “falso boldo” in Brazil, is used in herbal tea or cooked as a vegetable, and extracts from P. barbatus were analysed for their inhibition of acetylcholinesterase and their antioxidant activity as discussed by the authors.
Journal ArticleDOI
Synthesis of anatase TiO2 nanoparticles with high temperature stability and photocatalytic activity
TL;DR: In this article, a fast and easy method for preparing pure and stable nano-sized TiO2 anatase phase, using mild hydrothermal conditions, is presented, where the precursor is obtained via precipitation route using TiCl3 as starting material.
Journal ArticleDOI
Doped titanium dioxide nanocrystalline powders with high photocatalytic activity
Ana L. Castro,M. R. Nunes,Maria Deus Carvalho,Liliana P. Ferreira,Liliana P. Ferreira,Jean-Claude Jumas,F.M. Costa,M. H. Florêncio +7 more
TL;DR: In this article, the anatase structure of doped titanium dioxide nanopowders was investigated and the results showed an appreciable enhancement in the photoactivity of Sb:TiO2.
Journal ArticleDOI
Influence of the metabolic profile on the in vivo antioxidant activity of quercetin under a low dosage oral regimen in rats.
Marta R. Santos,M J Rodríguez-Gómez,M J Rodríguez-Gómez,Gonçalo C. Justino,Nuno Charro,M. H. Florêncio,Lurdes Mira +6 more
TL;DR: A first and crucial step to understand the mechanisms underlying potential health benefits of flavonoids is knowledge of their metabolites and their biological activities.
