In order to supply new information on the antioxidant function of selected beverages for nutritionists and the general public, total phenolic contents of 51 kinds of herbal and tea infusions made in China were measured by the Folin-Ciocalteu method, and their antioxidant capacities were evaluated using ferric reducing antioxidant power (FRAP) and Trolox equivalent antioxidant capacity (TEAC) as...

In acute clinical settings where there may be a role for antioxidant therapy, patients receive large amounts of i.v. fluids which may have antioxidant activity. To investigate such effects the antioxidant capacity of nine i.v. fluids was measured (Gelofusine, Haemaccel, 20% mannitol, 4.5% human albumin solution, fresh frozen plasma, aprotinin, N-acetylcysteine and two hydroxyethyl starch soluti...

results the results of the study, using the two methods, showed that all methanol extracts of leaves and fruits of the six species possessed antioxidant activity. the antioxidant activity of the samples was compared with the antioxidant activities of butylatedhydroxytoluene (bht), as a synthetic antioxidant and α-tocopherol as a natural antioxidant. methanol extractions of pinus spp. leaves and...

This study aimed to compare the antioxidant content and antioxidant capacity of pulp and peel of two varieties of pomelo fruit (Tambun White and Tambun Pink). Antioxidants including total phenolic content, total flavonoid content and ascorbic acid content were determined using Folin-Ciocalteu reagent assay, aluminium chloride colorimetric assay and AOAC method, respectively. Antioxidant capacit...

this study was designed to elucidate the effect of ascorbic acid on salivary total antioxidant capacity in smokers. in this single blind crossover clinical trial, the whole unstimulated saliva of 30 smokers, who were randomly divided into two groups, was collected. in the first phase after the saliva collection, one group of patients took 500 mg of vitamin c powder, for 3 weeks. then, saliva of...

ginger (zingiber officinale roscoe) contains the biological properties of the major standard non–volatile pungent compounds of ginger, namely, [6]–, [8]–, and [10]–gingerols, as well as [6]– , [8]–, and [10]–shogaols. so far, the comparative antioxidant potencies among shogaols and gingerols have not been studied in detail and reported. accordingly, this study aimed to examine and compare the a...

BACKGROUND Proteins have long been considered a principal target for oxidants as a result of their abundance in biological systems. However, there is increasing evidence about the significant antioxidant activity in proteins such as albumin. It is leading to new concepts that even consider albumin not only as an antioxidant but as the major antioxidant in plasma known to be exposed to continuou...
