The Specificity of Antioxidants: A Review
Abstract: Antioxidants are substances that provide protection to the body against reactive chemical species. When oxidative damage is not prevented or reversed, some pathology may occur. Naturally, there are enzymatic antioxidants (example: superoxide dismutase) and non-enzymatic (example: glutathione) in the cell, and some are incorporated through the diet (example: vitamins). These substances exhibit specificity when carrying out their activity, that is why it is necessary to experiment their effects on different …

Biochemical Assays of Crude and Purified Oxycarotenoid Extracts Isolated from Coriander Leaves and their Effect on Oxidative Stability of Oils by Rancimat Assay
Abstract: Antioxidants are important substances in the fight against the damage done by free radicals that are produced by oxidative stress. Antioxidants are available in various forms as dietary supplements/synthetic forms. Because of their toxicity and side effects, the extensive use of many of these synthetic antioxidants is ruled out. Most nutritionist agrees that, the natural food is the best source of antioxidants. Dietary antioxidants have the ability to scavenge free …

In vitro/In vivo Study of Anti-inflammatory Effect of Cyperus rotundus on Diabetic Complications
Abstract: The reactive oxygen species (ROS) develop oxidative stress that contributes to the cause of human diseases. Radicals which enhance inflammation are nitric oxide, hydroxyl radical, hydrogen peroxide, and superoxide. Anion mediate and amplify the inflammation process, mediate vascular permeability and platelet aggregation leading to diabetic complications due to disruption of steady state of pro-oxidants and antioxidants.

Acetoxylation of o, m Cresol by Electrochemical Process at Graphite Electrode
Abstract: Electrochemical processes remain unique because of the nature of specific products formed and their mode of formation in which current is a reactive input in place of redox reagents. The high yields of the products can be obtained by designing and optimizing the electrolysis. The ordinary chemical procedures are multi-staged and may result poor yields. Therefore the best way for minimizing the pollution is transformation of conventional chemical processes to …
