Objective: In this study, the levels and antioxidant activities of some secondary metabolites isolated from five pistachio (Pistacia vera)cultivars collected from four different geographical regions of Iran, were studied. Materials and Methods: Total phenolic compounds levels were determined by Folin-Ciocalteu method. Total flavonoid content was determined as AlCl3 complex and expressed as mg o...

A review of the literature indicates that numerous microorganisms can reduce ferric iron during the metabolism of organic matter. In most cases, the reduction of ferric iron appears to be enzymatically catalyzed and, in some instances. may be coupled to an electron transport chain that could generate A TP. However, the-physiology and biochem" istry of ferric irQn reduction are POQrly understood...

the anthocyanins of the fruit skin of iranian forest pear (sange khouj) were separated, identified and quantified using high-performance liquid chromatography/diode array detection (hplc/dad) and hplc/electrospray ionization /mass spectrometry (hplc/esi /ms). the individual anthocyanins were identified by comparing their mass spectral data and retention times with those of standards and publish...

the essential oil from the aerial parts ofjurinea leptoloba dc., collected from shiraz (south of iran), was investigated for total phenolic content (tpc), antioxidant and cytotoxic effects. tpc of j. leptoloba oil was determined to be 16.53 ± 5.69 μg gallic acid equivalent/mg sample (μg gae/mg oil) using the folin-ciocalteau assay. the ferric reducing power of the oil was determined 0.117 ± 0.0...

Aim: Evaluation of effect shodhana process datura seed (Datura stramonium) antioxidant activity. Methods: The was purified with two different processes viz. cow’s urine, and milk by Dolayantra method. Antioxidant activity evaluated in-vitro 1,1-Diphenyl-2-picryl hydrazyl (DPPH) radicals scavenging Ferric reducing power ability (FRPA) assay. Result: cow urine (CUD) showed a significant in inhibi...

conclusions the results showed that the effect of l. acidophilus is time-dependent. materials and methods antioxidant biomarkers, such as total antioxidant power (tap), measured with the frap (ferric-reducing ability of plasma) method, were evaluated at 24, 48, and 72 hours. results the results showed that extracts and bacteria of l. acidophilus were able to significantly increase tap after 24 ...

new sulfonamide and amide derivatives containing coumarin moieties; oxo-2h-chromen-sulfamoylphenylacetamides and oxo-2h-chromen-arylacetamides were synthesized starting from diverse 2-chloroacetamide derivatives and a wide range of coumarins. the structures of the obtained compounds were elucidated by ir and nmr spectra and also analytical elemental analysis. in the next step, the above mention...

BACKGROUND Herbal medicines played a major role in the treatment of hepatic disorders, and a number of medicinal plants and their compounds were widely used for the treatment of these disorders, and oxidant stress injury was one of the mechanism of liver injury. MATERIALS AND METHODS Antioxidant activity of Nelumbo nucifera leaves (NU) extracts was assayed by the methods of scavenging 1,1-dip...

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...

antioxidant activity of peucedanum pastinacifolium boiss. & hausskn aerial part hydroalcoholic extract (hae) and polyphenolic extract (ppe) as well as their total phenolic and flavonoid contents were studied. phenolic and flavonoid contents were respectively estimated as gallic acid and quercetin equivalents. the in vitro antioxidant activity of two extracts of p. pastinacifolium were evaluated...
