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...
متن کاملFerritin and superoxide-dependent lipid peroxidation.
Ferritin was found to promote the peroxidation of phospholipid liposomes, as evidenced by malondialdehyde formation, when incubated with xanthine oxidase, xanthine, and ADP. Activity was inhibited by superoxide dismutase but markedly stimulated by the addition of catalase. Xanthine oxidase-dependent iron release from ferritin, measured spectrophotometrically using the ferrous iron chelator 2,2'...
متن کاملPathological implications of nitric oxide, superoxide and peroxynitrite formation.
Introduction Approximately 6 years ago, nitric oxide was identified as the endothelium-derived relaxing factor (EDRF), the endogenous vasodilator mimicked by nitroglycerin and nitroprusside [ 1-41. An astonishing variety of tissues synthesize nitric oxide, which has important roles in the control of systemic blood pressure, respiration, digestion, penile erection, platelet aggregation, cerebral...
متن کاملInhibition of superoxide and ferritin-dependent lipid peroxidation by ceruloplasmin.
Ceruloplasmin (CP) was found to inhibit xanthine oxidase and ferritin-dependent peroxidation of phospholipid liposomes, as evidenced by decreased malondialdehyde formation. Ceruloplasmin was also shown to inhibit superoxide-mediated mobilization of iron from ferritin, in a concentration-dependent manner, as measured spectrophotometrically using the iron(II) chelator bathophenanthroline sulfonat...
متن کاملNitric Oxide, Superoxide, Hydrogen Peroxide, and Peroxynitrite
The evanescent nature of reactive oxygen and nitrogen species, the multiple cellular mechanisms evolved to maintain these substances at low (submicromolar) concentrations within the vascular system, and the often multifaceted nature of their reactivities have made measurement of these compounds within the vasculature problematic. This review attempts to provide a critical description of some of...
