Synthetic antioxidants are created through artificial synthesis, whereas natural synthesis in plants, animals, and microbes. Although synthetic have been used previously, there has a growing need recent years for antioxidants, largely due to the negative consequences of antioxidants. Therefore, many current studies focused on finding diverse plants. This study aimed compare effectiveness beef p...

Wheat grains and its fractions contain significant level of antioxidant activity and many phytochemicals, such as phenolic acids (ferulic and vanillic acids), carotenoids, and tocopherol are beneficial in curing many disorders. The beneficial phytochemicals are mostly present in aleurone fraction of wheat bran. The phytochemicals and antioxidants present in wheat have several health benefits, s...

Hydroxycinnamic acids (such as ferulic, caffeic, sinapic, and p-coumaric acids) are a group of compounds highly abundant in food that may account for about one-third of the phenolic compounds in our diet. Hydroxycinnamic acids have gained an increasing interest in health because they are known to be potent antioxidants. These compounds have been described as chain-breaking antioxidants acting t...

Ultrasound-assisted micellar extraction of phenolic antioxidants from spices has been developed for the first time. The effect of the surfactant nature and its concentration on the extraction efficiency has been evaluated. Electrogenerated hexacyanoferrate(III) ions have been used as coulometric titrants owing to their selectivity towards phenolic antioxidants. The best recovery of phenolic ant...

There are a great number of reports with assertions that oxidative stress is produced by organophosphorus compound (OPC) poisoning and is a cofactor of mortality and morbidity in OPC toxicity. In addition, antioxidants have been suggested as adjuncts to standard therapy. However, there is no substantial evidence for the benefit of the use of antioxidants in survival after acute intoxication of ...

INTRODUCTION Oxidative stress and antioxidants play an important role in the pathogenesis of inflammatory disease, including chronic periodontitis (CP). Saliva contains enzymatic (glutathione peroxidase - GPx, superoxide dismutase - SOD, etc.) and non-enzymatic (albumin - ALB, uric acid - UA, glutathione, etc.) antioxidants. OBJECTIVE The aims of this study were to investigate: a) level of SO...

The use of extracts of rosemary and other spices to combat oxidative rancidity is generating increased interest with consumer concerns over the use of synthetic antioxidants. Spice extracts are of interest because they have the advantage of being labeled as spices or natural flavors. The objective of this study was to evaluate the rancidity inhibition and color stability properties of various a...
