Antioxidants are compounds that protect cells against reactive oxygen cells – or free radicals -in the body. Although they are created as part of the body’s normal metabolic functions, free radicals react with other cells and may interfere with their ability to function. Free radicals are believed to play a role in many health conditions, ranging from cancer and atherosclerosis to wrinkles caus...

conclusions according to the obtained data, synthesized pyridine based chalcones (3a-3j) could be proposed as potential antioxidant lead compounds. background natural chalcones and also their synthetic derivatives have attracted increasing attention due to various pharmacological applications. development and discovery of new chalcones with antioxidant activities is one of the attracting areas ...

nowadays, the use of natural antioxidants as alternative antioxidants is more acceptable than synthetic antioxidants mainly for negative effects such as carcinogenicity and toxicity. this has led to an increasing interest in the search for natural antioxidants. the objectives of this study were to measure total crude phenolic compounds and in sorghum grain as natural antioxidant sources, to det...
