Free radical chemistry is characterized by an unregulated chain reaction of sequential oxidations and reductions that can rapidly amplify the concentration of reactive radicals. The free radical is defined by the occurrence of an unpaired electron in an organic molecule or metal ion (Halliwell & Gutteridge, 1989).

Free Radical Scavenging Properties of Wheat Extracts
Journal of Agricultural and Food Chemistry, 2002Three hard winter wheat varieties (Akron, Trego, and Platte) were examined and compared for their free radical scavenging properties and total phenolic contents (TPC). Free radical scavenging properties of wheat grain extracts were evaluated by spectrophotometric and electron spin resonance (ESR) spectrometry methods against stable 2,2-diphenyl-1 ...

Oxygen free radical scavenger properties of dehydroepiandrosterone
Cell Biochemistry and Function, 1998The microsomes from dehydroepiandrosterone (DHEA)-supplemented animals are good hydroxyl radical scavengers, as demonstrated through electron spin resonance and deoxyribose degradation. The ability of DHEA-supplemented microsomes to react with superoxide radical was also demonstrated through the inhibition of nitroblue-tetrazolium reduction determined ...

Free Radical-Scavenging Properties of Olive Oil Polyphenols
Biochemical and Biophysical Research Communications, 1998Plants in the Mediterranean basin, such as vine and olive trees, have developed an array of antioxidant defences to protect themselves from environmental stress. Accordingly, the incidence of coronary heart disease and certain cancers is lower in the Mediterranean area, where olive oil is the dietary fat of choice.

Radical scavenging ability of polyphenolic compounds towards DPPH free radical
Talanta, 2007Free radical scavenging activity of different polyphenolic compounds commonly present in wine has been evaluated using DPPH method. The experiments were performed with different amounts of phenols within the linear interval of response and with an excess of DPPH in all cases.

The Significance of Free Radicals and Free Radical Scavengers in L1210 Leukemia
1988L1210 leukemia is a murine leukemia which is associated with anemia and marked neutrophilia. In order to determine the significance of free radicals (FR) in this disorder, we determined the presence and localization of free radical scavengers (FRS) and scavenger-like systems in L1210 leukemia cells obtained in vivo and from in vitro cultures.

Oxygen Free Radicals and Radical Scavengers in Neurology
1990Free radicals have become fashionable in recent years. Hundreds of articles and many regional and national meetings have been devoted to them. The first international symposium on free radicals will take place this year in Vienna. Free radicals seem to be involved in one way or another in many diseases, such as cancer, ischemia, circulatory shock ...

Carbon Nanotubes as Free-Radical Scavengers
The Journal of Physical Chemistry C, 2008Density functional theory calculations have been used to model the potential ability of single-walled carbon nanotubes (SWCNT) to act as free-radical scavengers. The reactions of a (5,5) SWCNT fragment with six different radicals have been studied, and for hydroxyl radical, which is the most reactive and dangerous from all of the studied set, up to ...

Free radical scavenger activity of rutosides.
Minerva cardioangiologica, 2003The O-(beta-hydroxyethyl)-rutosides (HRs) are a standard mixture of flavonoid-derivatives that have a clinico-pharmacological activity on peripheral circulation, particularly on the endothelial cells of veins and lymphatics. Flavonoids are believed to prevent the oxidative damage derived from radical oxidative species (ROS), like hydroxyl radicals (HO.)
