background & aim: chemicals antioxidants and lipid oxidation products are known as cancer-causing factors in food systems. in this study, the effect of essential oil from heracleum lasiopetalum fruits on lipid oxidation and physicochemical properties of potato chips in comparison with commercial antioxidant has been investigated.experimental: the essential oil of h. lasiopetalum extracted u...

The aim of this study was to synthesize and examine possible in vitro antioxidant effects of indole-based melatonin analogue compounds. As a part of our ongoing study nineteen indole hydrazide/hydrazone derivatives were synthesized, characterized and their in vitro antioxidant activity was investigated by three different assays: by evaluating their reducing effect against oxidation of a redox s...

Thiazolidinediones (TZDs) are synthetic ligands of peroxisome proliferator-activated receptor-γ (PPARγ), a member of the nuclear receptor superfamily. TZDs are known to increase insulin sensitivity and also to have an antioxidative effect. In this study, we tested whether TZDs protect pancreatic β-cells from oxidative stress, and we investigated the mechanism involved in this process. To genera...

The present study investigated the antioxidant effect of a new class of quinoline derivatives (a-d) on assays in vitro. Lipid peroxidation, thiol peroxidase-like and free radical scavenging activities were determined to evaluate antioxidant activity of compounds. Thiol oxidase-like and δ-aminolevulinate dehydratase activities were performed as a toxicological parameter. A second objective of th...

the study was aimed at evaluating the antioxidant activity of hydroalcoholic solution extracts of urtica dioica l. (ud), malva neglecta wallr. (mn) plants and their mixture. in this study, flower (udf), root (udr), seed (uds) and leaf (udl) parts of ud and flower (mnf) and leaf (mnl) parts of mn were used. the antioxidant properties of hydroalcoholic extracts and their mixture were evaluated us...

This study was designed in such a way to assess the toxicity effect of 2,4D (Dichlorophenoxyacetic acid) pesticide in fish physiology and its antioxidant stress. Channa striatus fish were administered with two different doses compensation of 2,4-D pesticide of 100 and 200 mg/kg. After a matter of time interval the effect of 2,4-D on fish behavior and its toxic level was determined by assessing ...

The objective of the study was to investigate the anti-oxidant and anti-inflammatory effect of aqueous extract of Ocimum sanctum leaf. The antioxidant and anti-inflammatory activities were evaluated using in vitro Ferric reducing power, Free radical scavenging activity by DPPH method, hydroxyl radical scavenging activity, Nitric oxide radical scavenging activity, Hyaluronidase inhibition assay....

background: natural medicines have been recently considered more reasonable for human use most notably due to their safety and tolerance. hesa-a is a marine-originated herbal medicine with a variety of healing effects. however, its exact biological mechanism is not clear. the pre-sent study aimed at the evaluation of the hesa-a antioxidant effect. methods: chinese hamster ovary (cho) and human ...

RATIONALE Enhanced production of reactive oxygen species (ROS), capable of reducing endogenous defense levels and enhancing inflammation, is suggested to play a role in sarcoidosis. Antioxidant supplementation might offer protection against such ROS-mediated damage. A promising candidate for antioxidant supplementation is the flavonoid quercetin. AIM To determine the antioxidant and inflammat...

The antioxidant effect of aqueous-ethanolic extract from Astragalus glycyphylloides (Fabaceae), and its protection against carbon tetrachloride-induced hepatotoxicity were investigated in male Wistar rats. For seven consequent days the animals were treated orally with A. glycyphylloides extract (EAG) (100 mg/kg). Two hours after the last administration the animals were charged with carbon tetra...
