Antioxidants are groups of substances able to prevent and delay the oxidation of easily oxidizable molecules and avoid free radicals’ formation. In living organisms, the main free radicals are reactive oxygen species and reactive nitrogen species. At low levels, they are involved in the regulation of diverse physiological processes, but an imbalance ...

Antioxidant activity of retinoids
1990Publisher Summary Although the effects of retinoids are numerous in biological systems, among them are indications that retinoids may exert some of their actions by virtue of their acting as lipid-soluble antioxidants. In evaluating a substance as an antioxidant, it is important to use more than one assay, because an antioxidant may be very sensitive

Antioxidant activity of Erica arborea
Fitoterapia, 2007The antioxidant properties of the methanol extract of leaves and flowers of Erica arborea and the ethyl acetate, butanol and water soluble fractions were investigated. The ethyl acetate extract was found to be the richest for phenolic and flavonoid content which showed the highest antioxidant activity.

The antioxidant activity of caroverine
Biochemical Pharmacology, 2003Caroverine, 1-(2-diethylaminoethyl)-3-(p-methoxy benzyl)-1,2-dihydro-2-quinoxalin-2-on-hydrochloride, is a class B calcium-channel-blocker and antiglutamatergic agent with significant effects on the brain function. Caroverine exhibits competitive AMPA antagonism, and at higher concentrations, noncompetitive NMDA antagonism.

Antioxidant activity of Litsea cubeba
Fitoterapia, 2005The antioxidant activity of Litsea cubeba was studied in terms of three different assay systems: DPPH assay, peroxidase/guaiacol assay, and TBA test. The L. cubeba methanol extract and its fractions showed remarkable antioxidant activity in comparison with alpha-tocopherol and ascorbic acid.

Antioxidant activity of different dihydropyridines
Biochemical and Biophysical Research Communications, 2003Lacidipine, a dihydropyridine-based calcium antagonist (DHP), has already been demonstrated to possess antioxidant activity and to reduce the intracellular production of reactive oxygen species (ROS). To verify if this effect is a peculiarity of this molecule, or belongs to other DHPs, the activity of lacidipine was compared with those of amlodipine ...

ANTIOXIDANT ACTIVITIES OF ARTICHOKE PHENOLICS
Acta Horticulturae, 2005Both leaves and heads from artichokes are rich in phenolic compounds belonging to different classes: benzoic and cinnamic derivatives, flavonoids and tannins. There are conditions when these phenolic compounds show antioxidant activities and quench different types of free radicals.
