Reevaluating the role of 1,10-phenanthroline in oxidative reactions involving ferrous ions and DNA damage

Effect of Boiling on the Cytotoxic and Antioxidant Properties of Aqueous Fruit Extract of Desert Date, <em>Balanites aegyptiaca</em> (L) Delile

“…Hydroxyl radical-scavenging assay was carried out using the method described by de Avellar et al [16] with some modifications. Both 1,10-phenanthroline (0.75 mM) and FeSO 4 (0.75 mM) were dissolved in phosphate buffer (pH 7.4) and mixed thoroughly.…”

Antioxidant Activities and Inhibitory Effects of &lt;i&gt;Auricularia Auricular&lt;/i&gt; and Its Functional Formula Diet Against Vascular Smooth Muscle Cell &lt;i&gt;in Vitro&lt;/i&gt;

“…The total carbohydrate content in AAP was 42.5%, consisting of rhamnose, xylose, glucose, uronic acids, and sulfate as main composition besides smaller amounts of mannose, galactose, and arabinose, as reported in our previous research [10]. The total phenolic compounds in HPC and PPC was 102 and 53.5 mg/g, respectively, expressed as gallic acid equivalent.…”

“…The polysaccharides of A.auricula (AAP), polyphenolic components of hawthorn (HPC) and flavanoids components of Pueraria radix (PPC) were extracted and lyophilized according to our previous reported procedures [9,10]. Through our preliminary trials, the optimal formulation of weight ratio of three individual components in AHP was set as 5 (AAP): 3 (HPC): 2 (PPC).…”

In vitroantioxidant activity of protein fractions extracted from seinat (Cucumis melovar.tibish) seeds

“…These results show that the SSPH fractions are good scavengers of hydroxyl free radicals when compared to the values reported by Mau, Lin, and Song (2002) for BHA (23%) and α-tocopherol (34%) at concentrations of 3.6 and 8.6 mg/mL, respectively. One of the most commonly used iron chelators for the prevention of ironmediated OH formation in vitro, and also as a tool to indicate the participation of iron in oxidative stress processes is 1,10-phenathroline (de Avellar et al, 2004). In the presence of other competitive chelators, the [Fe(phen) 3 ] 2+ complex is disrupted, leading to the decrease in the dark orange color of the complex.…”
