The essential oils and aromatic water, known as Arak in traditional Iranian medicine, comes from the aerial part of Teucrium persicum Boiss., which is grown in Fars Province located in Iran. The samples were collected in summer and the oils and aromatic water were obtained through steam distillation. The chemical composition of the oils was analyzed using GC-MS. An analysis of the chemical...

oxygen free radicals may be implicated in the pathogenesis of ischemia reperfusion damage. as the antioxidant effects of some species of pistacia have been reported, the protective effects of pistacia vera l. gum extract (0.1-0.5 g/kg) on oxidative damage following cerebral ischemia were studied in rats. ischemia was induced using four-vessel occlusion model and evaluated using measurement of m...

A simple, automated test measuring the ferric reducing ability of plasma, the FRAP assay, is presented as a novel method for assessing "antioxidant power." Ferric to ferrous ion reduction at low pH causes a colored ferrous-tripyridyltriazine complex to form. FRAP values are obtained by comparing the absorbance change at 593 nm in test reaction mixtures with those containing ferrous ions in know...

enhanced oxidative stress in diabetes mellitus may contribute to the pathogenesis of diaetic complications. in this article, the stress oxidative generation has been studied in experimental diabetes by ferric reducing ability of plasma assay, a sensitive and simple method, and by other oxidative damage markers. the ferric reducing ability of plasma values as a total antioxidant capacity were si...

The properties of a ferric ion-reducing system which catalyzes the reduction of ferric ion with elemental sulfur was investigated with a pure strain of Thiobacillus ferrooxidans. In anaerobic conditions, washed intact cells of the strain reduced 6 mol of Fe with 1 mol of elemental sulfur to give 6 mol of Fe, 1 mol of sulfate, and a small amount of sulfite. In aerobic conditions, the 6 mol of Fe...

The study examined the phytochemical composition, DPPH radical scavenging activity, hydrogen peroxide scavenging radical activity, ferric reducing power, hemolytic inhibition, hemagglutination inhibition and antibacterial activity of methanol leaf extract of Ficus sycomorus and P. thonningii plant. The results showed the presence of tannins, saponnins, flavonoids, glycoside and phenols while te...

INTRODUCTION Calcium dobesilate is an antioxidant drug and this study is aimed to investigate the effects of calcium dobesilate on gentamicin-induced nephrotoxicity. MATERIAL AND METHODS This experimental study was conducted on 40 male Sprague-Dawley rats. The rats were randomly divided into the following 5 groups: control, sham, gentamicin (100 mg/kg/d, intraperitoneal), gentamicin and calci...

Aim of the study was to evaluate antioxidant activity and total phenolic content of Achyranthes coynei; an endemic plant used in treatment of several diseases in the same lines that of Achyranthes aspera by traditional practitioners of Belgaum region. Efficiency of extraction methods was studied for aerial parts (leaves, stem, and inflorescence) extracted in methanol using continuous shaking, m...
