the green synthesis of metallic nanoparticles is an active research area in nanotechnology. in the present study, antioxidant potential, total reducing capacity and silver nanoparticles (ag nps) synthetic potential of methanolic leaf extracts of seven plant species were evaluated and compared. antioxidant capacity, expressed as µmol trolox equivalents g-1 dw (µmol te g-1 dw), ranged from 116.0 ...

I describe a senstive colorimetric micromethod in which a pH 11.0 carbonate buffer is used to induce acetaminophen to react with Folin-Ciocalteau reagent at room temperature. These reagents and a simple solvent extraction favor formation of a stable indophenol dye with acetaminophen, giving this procedure a good degree of specificity. Results correlate well with those by liquid-chromatographic ...

About a year ago the writer (1) described technique for the determination of sugar in blood which yields figures appreciably lower than those obtained by the use of the older methods. Since the publication of that paper two investigators, employing widely differing procedures, have reported results which indicate the correctness of the lower figures obtained with the new method. Harned (2), aft...

Three spectrophotometric methods were evaluated in order to determine total phenolic compounds content in propolis from Tucumán, Argentina; applying the Folin-Ciocalteau, Prussian blue and ophenanthroline methods. The Prussian blue method was the most sensitive one although it was also unstable. The o-phenanthroline method may be more reliable and proved to be quite sensitive and stable. FolinC...
