Spatial correlations of total electron content (TEC) variability are compared among two SAMI3 model runs and Jet Propulsion Laboratory Global Ionospheric Maps (JPL/GIM). Individual monthly correlation maps constructed with Equatorial reference points at 12 evenly spaced longitudes universal times. TEC composite (TCCs) then calculated by averaging the individual maps, shifted zonally to synchron...

The word polyphenol is that chemical substance having more than one phenol group. Polyphenols represent a variety of compounds plant origin. have potential use in the human body. They act as antioxidants preventing oxidation other molecules by formation free radicals Most polyphenols properties reducing agents. protect cell constituents against oxidative damage. Therefore reduce risk various de...

Total phenolic contents (TPC) of five different extracts (petroleum ether, dichloromethane, ethyl acetate, ethanol and ethanol-water) of Artemisia biennis Willd were measured in this work. The antioxidant activity was investigated by three different methods: β-carotene bleaching (BCB) test, 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method and ferrous ion chelating (FIC) assay. Amo...

Ethanolic extract of leaves of Elaeocarpus ganitrus was analyzed for their total antioxidant capacity, reducing power, metal chelating, ABTS+ (2, 2-azinobis-(3-ethylbenzothiazoline-6-sulphonate) radical scavenging and hydroxyl radical scavenging activities. The extract at 500 ?g/ml showed maximum Iron chelating activity (76.70%) followed by the scavenging of the ABTS+ radical (55.77%) at the sa...
