Antioxidant Activity of Essential Oils
Journal of Agricultural and Food Chemistry, 2013Essential oils (EOs) are liquid mixtures of volatile compounds obtained from aromatic plants. Many EOs have antioxidant properties, and the use of EOs as natural antioxidants is a field of growing interest because some synthetic antioxidants such as BHA and BHT are now suspected to be potentially harmful to human health.

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.

Evaluation of Antioxidant Activity by Chemiluminescence
Analytical Biochemistry, 1997A sensitive and simple chemiluminescent method for measuring antioxidant activity was developed. The method is based on antioxidant-dependent quenching of chemiluminescence generated from lipid hydroperoxide and isoluminol/microperoxidase reagent. This method was used to evaluate the antioxidant ability of various antioxidants by measuring the half ...

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.

Antioxidant Activity in Cells and Organs
American Review of Respiratory Disease, 1987Abstract Antioxidant activity in cells occurs at several levels. The present work focuses on some aspects of enzymatic antioxidant defense. In particular, the so-called ancillary enzymes and transport systems are presented. Recent aspects on the control of the levels of antioxidant enzymes include the oxyR regulon in microorganisms as

Basic mechanisms of antioxidant activity
BioFactors, 1997A book originating from an annual meeting of the Oxygen Society (Charleston, South Carolina, 1995) [7] and dedicated to Paul Hochstein in occasion of his retirement is entitled The Oxygen Paradox: the preface and some interesting articles define The Oxygen Paradox as the dual effects of oxygen, in a manner reminiscent of Fridovich’s article 20 years ...
