In this work, an exhaustive survey of capillary electromigration methods used to analyze natural antioxidants is presented together with some discussion of the use of these substances use as functional foods. This review provides an updated and exhaustive overview of the separation and identification by capillary electrophoresis of natural compounds with antioxidant activity found in natural ma...

In order to find new sources of natural antioxidants, the antioxidant capacities of 50 medicinal plants associated with treatment of rheumatic diseases were systemically evaluated using the ferric-reducing antioxidant power (FRAP) and Trolox equivalent antioxidant capacity (TEAC) assays, and their total phenolic contents were measured by the Folin-Ciocalteu method. Their antioxidant activities ...

background & aim:extracts of roselle calyx,   possess compounds which could be considered as a great source of natural antioxidants.   in this project, antioxidant activities, phenolic compounds content and their   correlation analysis on calices of roselle (hibiscus sabdariffa) was investigated.  experimental: total polyphenolic compound, flavonoids and anthocyanins were determined spectrophot...

Background: Nowadays, natural antioxidants are used to replace synthetic antioxidants for delaying or preventing the oxidation of edible oils. In this study, phenolic compounds and antioxidant properties of methanol extracts of Spirulina microalgae (Arthrospira platensis) were measured. Methods: Phenolic content was measured by Folin–Ciocalteau method and antioxidant activity was measured by th...

background there is an interest in finding new and safe antioxidants from natural sources such as medicinal plants. objectives the aim of this study was to evaluate the antioxidant activity of ten iranian medicinal plants extracts. materials and methods for antioxidant activity, the radical scavenging activity, reducing power and phenolic contents of ethanol plant extracts were determined. gall...

BACKGROUND Use of antioxidants is a means of reducing rancidity of fats and oils in food stuffs. The commercial synthetic antioxidants in food industry have been suspected to cause negative health effects. Therefore as alternatives, there is a strong need in finding new effective and safe antioxidants from natural sources to prevent deterioration of foods, drugs and cosmetics. OBJECTIVES IN O...

There is evidence concerning the participation of reactive oxygen species in the etiology and physiopathology of human diseases, such as neurodegenerative disorders, inflammation, viral infections, autoimmune pathologies, and digestive system disorders such as gastrointestinal inflammation and gastric ulcer. The role of these reactive oxygen species in several diseases and the potential antioxi...
