Mechanisms of scavenging superoxide, hydroxyl, nitrogen dioxide and methoxy radicals by allicin: catalytic role of superoxide dismutase in scavenging superoxide radical

Radical and superoxide scavenging activities of matairesinol and oxidized matairesinol.

The radical and superoxide scavenging activities of oxidized matairesinols were examined. It could be assumed that the free benzylic position was important for higher radical scavenging activity. The different level of activity was observed between 7'-oxomatairesinol (Mat 2) and 7-oxomatairesinol (Mat 3). The activity of 8-hydroxymatairesinol was lower than that of matairesinol (Mat 1). The sup...

Superoxide dismutase Superoxide dismutase

Superoxide dismutase and superoxide radical in Morris hepatomas.

Total superoxide dismutase (SOD) and manganese superoxide dismutase (Mn SOD) specific activities were measured in tissue homogenates and in isolated mitochondria from normal rat liver and three Morris hepatomas of different growth rates. Total SOD and Mn SOD specific activities were decreased in all tumor homogenates when compared to normal liver; the lowest activity was associated with the fas...

Lipid Peroxidation Inhibition, Superoxide Anion and Nitric Oxide Radical Scavenging Properties of Thymus daenensis and Anethum graveolens Essential Oils

Background: Safety and efficacy of the synthetic antioxidants used in the food industry are frequently questioned because such antioxidants are unstable and highly volatile, therefore, interest in finding naturally occurring antioxidants that have the potential to protect human beings from damage induced by oxidative stress has intensified. Objective: Bioactivities of Thymus daenensis and Ane...

Superoxide anion scavenging activity ofCarthamustinctorius flower

In this study, ethanol extract of Carthamustinctoriuswas studied for superoxide anion scavenging activity. The antioxidant properties of Carthamustinctorius ethanol extract was evaluated using superoxide anion radical scavenging activities. The extract of Carthamustinctorius exhibited strong total antioxidant activity and superoxide anion scavenging activity. This antioxidant activity test were...
