Evaluation of free radical scavenging activity of some antioxidants.

UNLABELLED Measurement of free radical scavenging capacity of antioxidants is influenced by a number of parameters that depend on reaction rate. AIM A new method for assessing the free radical scavenging activity in which the influence of antioxidant concentration and reaction rate on chlorpromazine radical cation absorbance are simultaneously monitored. MATERIALS AND METHODS The change in ...

Free Radical Scavenging Activity of Some Plants Available in Malaysia

The present study was carried out to determine the free radical scavenging properties of some plants, found in Malaysia. The air-dried leaves of each plant (20 g) were soaked in distilled water (1:20; w/v) for 72 h at room temperature. Collected supernatants were tested for free radical scavenging activity against the DPPH and superoxide anion radical scavenging assays. All extracts were found ...

A clinical view of analytical goals in clinical biochemistry.

The analytical goals inferred desirable by a group of clinicians for the imprecisions of a wide range of analytes have been studied by survey. The goals required have not in general become more stringent in the past decade and are not as demanding as those promulgated by laboratory professionals. Clinical biochemistry laboratories can now attain analytical imprecisions which satisfy the general...

In Vitro Antioxidant and Free Radical Scavenging Activity of Alstonia scholaris Linn. R.Br.,

The present work is carried out to study the antioxidant potential of ethanolic extract of Alstonia scholaris Linn. ( Apocynaceae ) using various in vitro tests including 1,1-diphenyl-2-picryl-hydrazil (DPPH . ) free radical scavenging, metal ion chelating, hydrogen peroxide scavenging, superoxide anion radical scavenging, and ferric thiocyanate reducing ability.   Ethanolic ex...

Mechanisms of free radical chemistry and biochemistry of benzene.

omicron-Tyrosine (omicron-Tyr) was used as a specific biomarker for .OH radicals generated in biosystems. Specificity of omicron-Tyr as an .OH biomarker was based on previous studies in systems exposed to ionizing radiations. Fresh muscle tissue incubated with benzene for 1 hr at 38 degrees C exhibits formation of omicron-Tyr as seen in the cases of ethanol- and carbon tetrachloride-exposed sys...
