HPLC-DAD based method for the quantification of flavonoids in the hydroethanolic extract of Tonina fluviatilis Aubl. (Eriocaulaceae) and their radical scavenging activity
(Sociedade Brasileira de Química, 2014)
This article describes the isolation and identification of flavonoids in the hydroethanolic extract of the aerial parts from Tonina fluviatilis and evaluation of their antiradical activity. A method based on HPLC-DAD was ...
Flavonoids and fatty acids of Camellia japonica leaves extract
(Sociedade Brasileira de Farmacognosia, 2011-12-01)
The ethanol extract from the leaves of Camellia japonica L., Theaceae, showed antiradical potential in the DPPH test using TLC plates (SiO2). Aiming the isolation of active compounds, this extract was partitioned between ...

Antiradical capacity of a series of organotin(IV) compounds: A chemical reactivity study in the Density Functional Theory framework
(2014)
Here we explore in the Density Functional Theory (DFT) framework the antiradical activity of picolinic (PA), nicotinic (NA) and isonicotinic (INA) acids and a group of derivative stannoxanes of the type RC(O)OSnX3. Using ...

Theoretical study of the reaction mechanism of a series of 4-hydroxycoumarins against the DPPH radical
(Elsevier Science, 2014-05)
Structural, electronic and energetic characteristics of a series of 4-hydroxycoumarin derivatives have been studied using DFT to elucidate the mechanisms involved in their antiradical activities against DPPH radical. ...
