In this study, ethanol extract of Carthamustinctoriuswas studied for superoxide anion scavenging activity. The antioxidant properties of Carthamustinctorius ethanol extract was evaluated using superoxide anion radical scavenging activities. The extract of Carthamustinctorius exhibited strong total antioxidant activity and superoxide anion scavenging activity. This antioxidant activity test were...

The free radical scavenging potential of the leaves of A. squamosa was studied by using different antioxidant models of screening. The ethanolic extract at 1000 microg/ml showed maximum scavenging of the radical cation, 2,2-azinobis- (3-ethylbenzothiazoline-6-sulphonate) (ABTS) observed upto 99.07% followed by the scavenging of the stable radical 1,1-diphenyl, 2-picryl hydrazyl (DPPH) (89.77 %)...

Traditional plants contain various secondary metabolites such as alkaloids, terpenoids, steroids and phenolic compounds which have shown antioxidant activities that include scavenging free radical species and inhibiting the production of reactive species resulting from normal cell metabolism. The present study was undertaken to analyse the thin layer chromatography and antioxidant activities of...

restoring fucosylation. In the absence of fucose, the FX / mice display a profound neutrophilia. Part of this neutrophilia can be explained by loss of selectin ligands (Sialyl Lewis x contains fucose), but proliferation of myeloid progenitor cells suggests that myelopoiesis is being stimulated. Zhou and coworkers have now examined the proliferation of myeloid lineages in FX / mice and attribute...

[1] Wet scavenging is an important sink term for many atmospheric constituents. However, production of precipitation in clouds is poorly understood, and pollutant removal through wet scavenging is difficult to separate from removal through dry scavenging, atmospheric mixing, or chemical transformations. Here we use airborne data from the International Consortium for Atmospheric Research on Tran...

Enzyme hydrolysates (trypsin, papain, pepsin, α-chymotrypsin, and pepsin-pancreatin) of Tinospora cordifolia stem proteins were analyzed for antioxidant efficacy by measuring (1) 1,1-diphenyl-2-picrylhydrazyl (DPPH•) radical scavenging activity, (2) 2,20-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS+) radical scavenging capacity, and (3) Fe2+ chelation. Trypsin hydrolysate showed the s...

The free radical scavenging activities of n-hexane extract of the whole plant of Emilia sonchifolia was evaluated by employing various in vitro assay systems like DPPH radical scavenging activity, superoxide radical scavenging activity and hydrogen peroxide scavenging activity with IC50 values 180, 160 and 160 μg/ml respectively. The results of the study indicate that the n-hexane extract of th...

Rhizoma Atractylodes macrocephala (AM) has been used in Traditional Chinese Medicine (TCM) for about 2,000 years. In the study, we firstly determined the antioxidant levels of five AM extracts by •OH-scavenging, •O2−-scavenging, Fe2+-chelating, Cu2+-chelating, DPPH·-scavenging, and ABTS+·-scavenging assays. After measurement of the chemical contents in five AM extracts, we quantitatively analyz...

Electrochemically reduced water (ERW) is produced near a cathode during electrolysis and exhibits an alkaline pH, contains richly dissolved hydrogen, and contains a small amount of platinum nanoparticles. ERW has reactive oxygen species (ROS)-scavenging activity and recent studies demonstrated that hydrogen-dissolved water exhibits ROS-scavenging activity. Thus, the antioxidative capacity of ER...
