Use of a Free Radical Method to Evaluate Antioxidant Activity
The antiradical activities of various antioxidants were determined using the free radical, 2,2-Diphenyl-1-picrylhydrazyl (DPPH*). In its radical form. DPPH* has an absorption band at 515 nm whichExpand
Kinetics and Mechanisms of Antioxidant Activity using the DPPH.Free Radical Method
Abstract The reaction mechanisms of three antioxidants are proposed in order to explain experimental results obtained from a kinetic study using the free radical 2,2-diphenyl-1-picrylhydrazyl (DPPH .Expand
Antioxidant activity and phenolic composition of citrus peel and seed extracts
A possible way to valorize citrus peels and seeds, which are byproducts of the juice extraction industry, is to use them as natural antioxidants. The antioxidant activity of several citrus peel and...
Antioxidative activity and phenolic composition of pilot-plant and commercial extracts of sage and rosemary
Eight sage (Salvia officinalis) and twenty-four rosemary (Rosmarinus officinalis) extracts, originating from pilot-plant or commercial sources, had different antioxidative activities as measured byExpand
Antioxidant Constituents in Sage (Salvia officinalis)
The antioxidant compounds of oleoresin of sage (Salvia officinalis) were separated by column chromatography and high-performance liquid chromatography. Sir major compounds were purified andExpand
Antioxidant activity of phenolic compounds in 2,2′-azobis (2-amidinopropane) dihydrochloride (AAPH)-induced oxidation: Synergistic and antagonistic effects
Interactions between phenolic antioxidants in binary systems were determined by adding two antioxidants simultaneously in equimolar proportions to an aqueous dispersion of linoleic acid that was thenExpand
Sulfated ferulic acid is the main in vivo metabolite found after short-term ingestion of free ferulic acid in rats.
TLDR
It is suggested that a part of FA incorporated in the diet was quickly absorbed and largely metabolized in sulfoconjugates before excretion in urine. Expand
Evolution of antioxidant activity during kilning : role of insoluble bound phenolic acids of barley and malt
Phenolic acids, bound to the cellular walls of the germinated barley, are very interesting potential antioxidants of beer. Indeed, the antioxidant activity due to these bound compounds is aboutExpand
Bound ferulic acid from bran is more bioavailable than the free compound in rat.
TLDR
The results show the good bioavailability of FA from bran and its potential efficiency to protect organism against pathology involving radical steps of development. Expand
