A New Lichen Depsidone from L Obaria Pulmonaria
(Inst Materials Physics, Bucharest, 2012)
The continuation of our phytochemical survey of Lobaria pulmonaria (L.) Hoffm. (Lobariaceae), has led to the isolation and identification of a new lichen depsidone (1) characterised by the normal analytical and spectroscopic ...
Ethylene oxide removal by sorption on aluminium oxide / Uklanjanje etilen oksida sorpcijom na aluminijum oksidu
(Association of Chemical Engineers of Serbia, 2009)
The dynamics of ethylene oxide sorption and desorption on Al2O3 sorbent were investigated. The investigations of ethylene oxide sorption on Al2O3 show that significant sorption appeared above 125°C. The removal of sorbed ...
Investigation of antibacterial activity of cinnamyl derivatives of arylpiperazine
(Inst Bioloska Istrazivanja Sinisa Stankovic, Beograd, 2012)
The derivatives of cinnamic acid and N-arylpiperazine show antibacterial activity. In this work the potential synergistic effect of cinnamyl derivatives of arylpiperazine in selected bacteria was investigated. The antibacterial ...
Heavy metal and trace element bioaccumulation in target tissues of three edible predatory fish species from bovan reservoir (Serbia)
(Parlar Scientific Publications, 2014)
Pikeperch (Sander lucioperca), catfish (Silurus glanis) and pike (Esox lucius) were collected from the Bovan Reservoir (Southeast Serbia), and samples of muscle, liver and gills were analyzed for Cu, Zn, Pb, Cd, Hg, Cr and ...
A study of the electrochemical activity of some macrolide antibiotics on a gold electrode in a neutral electrolyte / Proučavanje elektrohemijske aktivnosti nekih makrolidnih antibiotika na elektrodi od zlata u neutralnom elektrolitu
(Serbian Chemical Society, 2007)
The aim of the present study is to present the different reactivity of azithromycin and clarithromycin (pure and commercial) at a gold electrode in neutral electrolyte using cyclic linear sweep voltammetry under the same ...
Sesquiterpene lactones, lignans and flavones of Centaurea affinis

Aerial parts of Centaurea affinis Friv. were collected at Vlasina (east Serbia) in September 1998.
Planar chromatography of cholic acid-derived cis-trans isomeric bis-steroidal tetraoxanes
(Journal of Planar Chromatography - Modern TLC, 2009)
Seven pairs of cis-trans isomers of bis-steroidal tetraoxanes have been examined by both normal-phase (NP) and reversed-phase (RP) planar chromatography. Unmodified silica gel was used with ethyl acetate-toluene and ethyl ...
Summertime PAH assembly in Mediterranean air: The Herceg Novi sampling station as an example / Летњи садржај ПАУ у медитеранском ваздуху : мерна станица Херцег Нови као пример
(Belgrade : Serbian Chemical Society, 2007)
The results of an analysis of the total suspended particles (TSP), total solvent organic extracts (TSOE), and polycyclic aromatic hydrocarbons (PAHs) in aerosol samples collected from the atmosphere of Herceg Novi from ...
Effect of MnSOD (E. coli) on the relaxation caused by sodium nitroprusside on isolated rat renal artery / Efekat MnSOD (E. coli) Na relaksaciju izolovane renalne arterije pacova izazvanu natrijum-nitro-prusidom
(Serbian Chemical Society, 2004)
In this study themolecular foundation of nitric oxide induced relaxation of arteries, with or without endothelium, of normotensive and spontanously hypertensive ratswas re-examined. With this purpose in mind, the effects ...
Structural effects of metallic chromium on its electrochemical behavior / Uticaj strukture metalnog hroma na njegovo elektrohemijsko ponašanje
(Serbian Chemical Society, 2007)
Chromium dissolution in aqueous sulfuric acid solution of pH 1 was studied electrochemically on chromium electrodes with different crystallographic structures. A slow potentiodynamic method was used for the electrochemical ...
