This study aimed to analyse the chemical profiles of Hylotelephium species, hybrids, and cultivars in terms headspace (HS) volatiles (by GC‐MS/FID) elemental composition (macro‐/microelements) roots leaves ICP‐OES). Contrary root HS fraction, fraction leaf did not contain any volatiles. Generally, oxygenated monoterpenes are a dominant class volatiles, with monoterpenic alcohol myrtenol as major compound followed by 1‐octen‐3‐ol. Regarding content macroelements, analyzed samples mostly...

An inductively coupled plasma atomic emission spectrometry (ICP AES) method for determination of 21 elements (Al, As, B, Ba, Ca, Cd, Cr, Co, Cu, Fe, K, Mg, Mn, Na, Ni, P, Pb, Si, Se, V and Zn) in Rosa corymbifera Borkh. samples was optimized then validated. Robust conditions were reached at a radiofrequency power (RF) 1150 W an argon nebulizer flow (NBF) 0.5 L min-1. All experiments axial radial view mode conducted under these analytical conditions. The validation process included accuracy,...

An inductively coupled plasma-optical emission spectrometry method for the speedy simultaneous detection of 19 elements in edible nuts (walnuts: Juglans nigra; almonds: Prunus dulcis; hazelnuts: Corylus avellana; Brazil nuts: Bertholletia excelsa; cashews: Anacardium occidentalle; pistachios: Pistacia vera; and peanuts: Arachis hypogaea) available on Serbian markets, was optimized validated through selection instrumental parameters analytical lines free from spectral interference with lowest...

The aim of this research was to determine the total phenolic and flavonoid contents as well measure antioxidant activity 24 different commercial beers consumed in Serbia. major acids (gallic acid, protocatechuic 4-hydroxybenzoic 2,5-dihydroxybenzoic vanillic caffeic syringic p-coumaric ferulic sinapic salicylic), (+)-catechin, (-)-epicatechin were also determined by high pressure liquid chromatography method using a photodiode array detector. Gallic acid are most abundant all samples,...

Abstract The aim of this work was to determine the content 22 macro- and microelements in ten raw Serbian propolis samples which differ geographical botanical origin as well polluted agent contents by atomic emission spectrometry with inductively coupled plasma (ICP-OES). macroelements were more common present Ca highest while Na lowest. Among studied essential trace elements Fe most element. levels toxic (Pb, Cd, As Hg) also analyzed, since they possible environmental contaminants that...

Introduction.Among different fruit species, aronia have attracted a great attention because of its wide range protective effects with potential benefits for human health.Furthermore, the consumption products (juice, tea, berries) is becoming part healthy lifestyle.Materials and Methods.The multi-element characterization has been carried out using inductively coupled plasma atomic emission spectrometry (ICP-AES).Results Discussion.Among major elements, most abundant are K, Ca P, followed by...

Purpose: To evaluate the macro- and micro-nutrient elements of some commercially available fruit juices in Serbia.Methods: Inductively coupled plasma optical emission spectrometry (ICP-OES) technique was employed for determination major minor samples two different types - clear cloudy.Results: Among macro-nutrient elements, potassium (K) had highest content 230.17 μg/g multivitamine cloudy juice. The K higher than juices. iron, which is among group trace ranged from 2.237 to 5.911 3.55 10.05...

ABSTRACTThe ability of the maize hybrid ZP666 to uptake cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), and lead (Pb) from artificially contaminated soil in a pot experiment was investigated. The applied ICP-OES methods are satisfactory accuracy (Recovery values 88.9 103.0%) negligible matrix effect (slope ratio 0.95 1.11). determined contents investigated heavy metals plant parts maize, mass roots, stems leaves, height aboveground as well BCF (Biological Concentration Factor), MR...

Inductively coupled plasma optical emission spectroscopy, in combination with calculation of various biological factors, was used this study not only for a simple illustration the present status some essential and non-essential metals such as copper (Cu), zinc (Zn), nickel (Ni), lead (Pb), arsenic (As), cadmium (Cd) grapevine cultivar Rkatsiteli wild blackberry from East Serbia but also estimation plant bioaccumulation potentials. Great majority detected metal concentrations were normal...

Storage stability of catechin, epicatechin, procyanidins B1-B4 and total flavonoids in cocoa powder samples was studied over the temperature range 4-35?C. Thermal 95-125?C. Total concentration decreased as a function time degradation accelerated at higher temperatures: half-life (t1/2) much shorter room than during cold storage. A first-order kinetic model fitted well to all data. Temperature dependence rate constants, described by Arrhenius equation, more pronounced heating In interval from...
