Chemical Profile, Radical Scavenging and Cytotoxic Activity of Yellow Gentian Leaves (Genitaneae luteae folium) Grown in Northern Regions of Montenegro
(Natural Products Inc, Westerville, 2012)
LC-ESI-MS and HPLC were used for the identification of the constituents from G. lutea leaves collected at different localities, as well as for quantification of the main compounds. Seven secoiridoids, five C-glucoflavones ...
Formation of two-dimensional (2D) lead dendrites by application of different regimes of electrolysis
(Springer, New York, 2012)
Electrodeposition of lead from nitrate electrolyte in constant regimes of electrolysis was analyzed and the obtained powder lead deposits were examined by scanning electron microscopy. Polarization curve for lead ...
Density functional theory study of the magnetic coupling interaction in a series of binuclear oxalate complexes
(Springer Wien, Wien, 2012)
Magnetic couplings in oxalate-bridged binuclear complexes, namely five isomers of [(VO)(2)(ox)(SCN)(6)](4-), trans-(equatorial, equatorial), cis-(equatorial, equatorial), trans-(axial, axial), cis-(axial, axial), and (axial, ...
Kinetic Analytical Method for Determination of Uric Acid in Human Urine using Analyte Pulse Perturbation Technique
(Sociedade Brasileira de Química, 2012)
Simple and reliable novel methods for the determination of uric acid (UA) are proposed and validated. For quantitative determination of UA, two matrices were used: the Bray-Liebhafsky (BL) oscillatory reaction in a stable ...
