The present study aims to evaluate the antioxidant potential of methyl gallate an ester of gallic acid in different in vitro assays. The antioxidant capacity was assessed using Molybdate ion reduction, DPPH, ABTS radical cation scavenging, deoxyribose degradation (site specific and non-site specific), reducing power, lipid peroxidation, superoxide anion scavenging, chelating power and DNA nicki...

The aim of the present study was to evaluate the effect of troxerutin (TXN) on Nickel (Ni) toxicity by using rats and in vitro model. Ni toxicity induced in male albino wistar rats (20 mg/kg body weight (b.w) was administered orally for 20 days). TXN was administered orally (100 mg/kg (b.w) for 20 days with administration of Ni. The toxic effect of Ni and the action of TXN was measure by determ...

Essential oils from plants have been proven safe as natural antioxidants, and few are already marketed as digestive enhancers as well as in prevention of several degenerative diseases. This study evaluated the antioxidant capacity of seed and shell essential oils of Abrus precatorius (L), a herb used for ethno-medicinal practices in Nigeria. The essential oils were obtained by hydro-distillatio...

Background: Radioprotective efficacy of Prunus avium fruit extract (PAE) rich in vitamin A, C, E and anthocyanin was studied against radiation induced biochemical alterations in mice brain. Materials and Methods: In-vitro assays were performed with PAE for its antioxidant studies thereafter for in-vivo study, Swiss albino mice were divided into five groups. Group 1 (control) normal mice. Group ...

Background: Levan or fructan, a polysaccharide of fructose, is widely used in various commercial industries. Levan could be produced by many organisms, including plants and bacteria. The cloning of the gene from Bacillus licheniformis, which expressed levansucrase in E. coli host, was carried out successfully.  In the present study, we performed the in vitro production of levan and analyzed its...

Comparative antioxidant activities of the water and ethanol extracts obtained from dried citrus fruit (Citrus unshiu) peel were determined using chemical and biochemical in vitro assays. Chemical assays were used for evaluation of 1,1-diphenyl-2-picryl hydrazyl (DPPH) radical scavenging, hydrogen peroxide scavenging, and reducing power of both extracts and their total phenolic, flavonoid and ta...

OBJECTIVE To examine the antioxidant activity and total phenolic content of different solvent fractions of Pedalium murex (P. murex) Linn fruits (Family: Pedaliaceae) as well as the correlation between the total antioxidant capacity and total phenolic content. METHODS In the present study, the antioxidant activities of P. murex were evaluated using six in-vitro assays, namely total antioxidan...

PURPOSE The paper tried to systematically investigate the in vitro antioxidant activity of Rhizoma Cibotii (RC) for the first time. METHOD The methanol extract from RC (MERC) was prepared then systematically investigated by various antioxidant assays, including: DPPH• (1, 1-diphenyl-2-picrylhydrazyl radical), ABTS•(+) (3-ethylbenzthiazoline-6- sulfonic acid diammonium salt radical), •O2- (sup...

The present investigation highlights the free radical scavenging activity of Melochia corchorifolia, Sida acuta and Saccharum officinarum leaf extracts and their Phenolic contents by determining DPPH, Nitric oxide, Hydroxyl and Hydrogen peroxide scavenging activity. The shade dried leaves were coarsely powdered and subjected to fractional extraction by using chloroform and ethanol. The extracts...

Chick embryo egg hydrolysates (CEEH) were obtained by enzymatic hydrolysis of chick embryo egg in vitro-simulated gastrointestinal digestion. The antioxidant activities of CEEH were investigated by employing three in vitro assays, including the 2,2'-azinobis-(3-ethylbenzthiazoline-6-sulfonate)/1,1-diphenyl-2-picrylhydrazyl (ABTS/DPPH)/hydroxyl radical-scavenging assays. The radical-scavenging e...
