AB  - Oilseed crops are widely cultivated and are related to nutrition and human health as
valuable nutraceutical sources with valuable biological properties. The growing demand for oil
plants used in human and animal nutrition or for the processing industry has contributed to the
diversification and development of a new variety of oil crops. Increased oil crop diversity, besides
ensuring reduced sensitivity to pests and climate conditions, has also led to improved nutritional
values. In order to enable oil crop cultivation to become commercially sustainable, a comprehensive
characterization of newly created varieties of oilseeds, including their nutritional and chemical
composition, is required. In this study, two varieties of safflower and white and black mustard were
investigated as alternative oil species for nutritional parameters, mainly protein, fat, carbohydrate,
moisture, ash, polyphenols, flavonoids, chlorophylls contents, acids and mineral composition, and
compared with those of two different genotypes of rapeseeds as a traditional oil crop plant. The
proximate analysis found that the highest oil content was found in the oil rape NS Svetlana genotype
(33.23%), while the lowest was in black mustard (25.37%). The protein content varies from around 26%
in safflower samples to 34.63%, determined in white mustard. High content of unsaturated fatty acids
and low content of saturated fatty acid was observed in the analyzed samples. In mineral analysis,
the dominant elements were phosphorus, potassium, calcium and magnesium, in descending order.
The observed oil crops are also good sources of microelements, including iron, copper, manganese
and zinc, accompanied by high antioxidant activity due to the presence of significant amounts of
polyphenolic and flavonoid compounds

AB  - Catechin is a flavonoid compound with polyphenolic structure naturally occurring in plants, fruits, tea, red
wine and cacao products. Many beneficial effects are associated with catechin consumption such as
antioxidant, anticarcinogenic, anti-inflammatory, antiatherogenic, antibacterial and antiviral activity.
Determination of catechin is typically based on the use of high-performance liquid chromatography, but also
methods such as spectrophotometry and capillary electrophoresis are reported.
In this work we investigated the use of different modifications of a carbon paste electrode (CPE) for
voltammetric determination of catechin. The reason for introducing a modifier into the carbon paste was to
increase the sensitivity of the voltammeircic techniques, due to the catalytic effect of the modifier on the
electrode processes. Multi-walled carbon nanotubes (MWCNTs), antimony(Ill) oxide and bismuth
nanoparticles are investigated as bulk modifiers for preparation of CPE with concentration of 5% (w/w).
Electroanalytical measurements are performed in 0.1 M phosphate buffer pH 7.0 using cyclic voltammetry
and square wave voltammetry, in the concentration range from 1 to 20 mg/dm* of catechin.
Two oxidation peaks of catechin are observed for all studied modified CPEs and bare CPE, with significantly
higher intensity of the first peak. The results also showed improvement of sensitivity by using the modified
CPEs in comparison to unmodified CPE. The application of MWCNTs as a modifier contributed to the
highest sensitivity for catechin determination in relation to the other modifiers. These preliminary results
show that MWCNTs modified CPE can be used as a very sensitive sensor for catechin determination in real
samples.

AB  - Novel electroanalytical procedures are developed for determination of different pesticides content in commercial
pesticide formulations using chronopotentiometry. As a working electrode glassy carbon electrode and thin film
mercury electrode are used for determination of insecticide imidacloprid and herbicides metamitron and metribuzin.
For all determined pesticides one reduction peak is obtained, as a result of irreversible reduction of the analyte on the
working electrode. Quantification of pesticides in commercial formulations is performed after optimization and
validation of the chronopotentiometric method. Samples of commercial pesticide formulations are primarily dissolved
in doubly distilled water, acetonitrile and ethanol for imidacloprid, metamitron and metribuzin, respectively.
Ultrasound treatment in duration of 2 min is used to support dissolution. The final dilution is performed in the BrittonRobinson buffer of optimal pH value. Quantitative determination of the pesticide is performed using the calibration
curve method, while every sample is analyzed in triplicate. Obtained average recovery and RSD value for 13 samples
of commercial pesticide formulations is 100.22% and 0.01%, indicating on the accuracy and precision of the
chronopotentiometric method.

AB  - Sunflower seed cake is remaining after isolation of oil from sunflower seeds and practically
represents a waste from production of cold pressed sunflower oils. This waste product is
consider as a viable potential source of various natural compounds and can be exploited for
the production of new products and isolation of valuable substances such as biologically
active compounds and nutraceuticals. In addition, isolation of biologically active substances
from food waste represents the way for recycling and may be economically attractive as well.
Flavonoids represent a group of polyphenol compounds with a high antioxidant power. These
phytochemicals are known to reduce many chronic diseases such as cardiovascular diseases,
heart diseases, diabetes, obesity and certain cancer [1]. In this work we investigated the
flavonoids content in seven sunflower seed cakes coming from cold pressed oil production.
Flavonoids are extracted by using 80% ethanol and ultrasound-assisted extraction at 30°C for
10 minutes. Total flavonoid content is determined by a colorimetric method [2]. The results
showed that sunflower seed cakes contained significant amounts of total flavonoids. The total
flavonoids content is found to be in the range from 12.3 to 24.6 mg of catechin equivalent/g.
The results proved that sunflower seed cakes obtained from cold pressed oil production
represent valuable by-product and can be used as a raw material for isolation of bioactive
flavonoids which could be further applied for development of various functional foods.

AB  - Seme suncokreta se odavnina koristi u Ijudskoj ishrani i u danaSnje vreme predstavlja jednu
od najvise gajenih uljanih kultura u svetu. Razlikuju se dva tipa suncokreta koji se gaje, uljani
tip | konzumni tip. Uljani tip suncokreta se proizvodi za dobijanje jestivog biljnog ulja, dok
se konzumni suncokret odlikuje manjim sadrzajem ulja i visokim sadrzajem proteina i drugih
bioloski aktivnih jedinjenja, i koristi se preteZno za lIjudsku ishranu usled visoke hranljive
vrednosti. U poslednje vreme, mogucnost proizvodnje ulja od konzumnog suncokreta je
predmet interesovanja kako u nauénim krugovima, tako i u krugovima proizvodaga i
preradivaéa. Ulja iz konzumnog suncokreta dobijaju se cedenjem, tj. primenom mehanickih
presa i delovanjem sile na seme. Nerafinisano, hladno cedeno ulje poseduje karakteristi€na
senzorna svojstva i sadrzi ocuvane bioaktivne komponente koje poti€u iz semena
suncokreta. Usled odsustva rafinacije, ova ulja su specificna po svom izgledu, boji, mirisu i
ukusu, hemijskom sastavu, nutritivnoj vrednosti i odrzivosti. Nakon mehanickog izdvajanja
ulja presovanjem semena zaostaje pogaca koja prakti¢no predstavija otpad iz prehrambene
industrije i najéeée se koristi za ishranu Zivotinja. Pored visokog sadrzaja proteina, pogaca
sadrizi znaéajne koliéine biologki aktivnih jedinjenja, te moze predstavijati polaznu sirovinu
za dobijanje ekstrakata koji sadrze visoko vredna jedinjenja i koji bi dalje mogli da se koriste

abstract = "Seme suncokreta se odavnina koristi u Ijudskoj ishrani i u danaSnje vreme predstavlja jednu
od najvise gajenih uljanih kultura u svetu. Razlikuju se dva tipa suncokreta koji se gaje, uljani
tip | konzumni tip. Uljani tip suncokreta se proizvodi za dobijanje jestivog biljnog ulja, dok
se konzumni suncokret odlikuje manjim sadrzajem ulja i visokim sadrzajem proteina i drugih
bioloski aktivnih jedinjenja, i koristi se preteZno za lIjudsku ishranu usled visoke hranljive
vrednosti. U poslednje vreme, mogucnost proizvodnje ulja od konzumnog suncokreta je
predmet interesovanja kako u nauénim krugovima, tako i u krugovima proizvodaga i
preradivaéa. Ulja iz konzumnog suncokreta dobijaju se cedenjem, tj. primenom mehanickih
presa i delovanjem sile na seme. Nerafinisano, hladno cedeno ulje poseduje karakteristi€na
senzorna svojstva i sadrzi ocuvane bioaktivne komponente koje poti€u iz semena
suncokreta. Usled odsustva rafinacije, ova ulja su specificna po svom izgledu, boji, mirisu i
ukusu, hemijskom sastavu, nutritivnoj vrednosti i odrzivosti. Nakon mehanickog izdvajanja
ulja presovanjem semena zaostaje pogaca koja prakti¢no predstavija otpad iz prehrambene
industrije i najéeée se koristi za ishranu Zivotinja. Pored visokog sadrzaja proteina, pogaca
sadrizi znaéajne koliéine biologki aktivnih jedinjenja, te moze predstavijati polaznu sirovinu
za dobijanje ekstrakata koji sadrze visoko vredna jedinjenja i koji bi dalje mogli da se koriste

AB  - Electrochemical detection of various contaminants has been widely used as a powerful tool in quality
control of food and analysis of environmental samples. In this work, electrochemical procedures for
determination of pesticides imidacloprid, metribuzin and metamitron are presented. Thin film layer
electrode is used as a working electrode, while chronopotentiometry is applied as an electroanalytical
technique. For all analysed pesticides, several solution conditions and instrumental parameters
influencing the electroanalytical response of the analytes are examined and optimised in respect to the
height of the analytical signals. The obtained analytical signals for the investigated pesticides are the
result of irreversible reduction of the analyte on the working electrode surface, and for each analyte
one reduction wave is obtained. Under the optimal experimental conditions, proposed
chronopotentiometric methods are validated with the respect to linearity, limit of detection, limit of
quantification, precision, selectivity, recovery and accuracy. Validated chronopotentiometric methods
are applied for analysis of selected pesticides in spiked tap and river water samples. In the analysis of
real samples, proposed methods showed to be sensitive and reproducible, fast (1-5 s analysis time),
and simple since no complicated sample preparation is needed, and therefore are suitable for routine
analysis of pesticides in water samples.

AB  - Rimsulfuron, prosulfuron and oxasulfuron are a group of sulfonylurea herbicides that have
been widely used for controlling weeds in a variety of vegetables and other crops. Because of
the high herbicidal activity of this sulfonylureas, they are beneficial at low application rates
which are approximately 1000 times less than other of convencional herbicides. Hence the
using of this herbicides is increasing constantly worldwide.
The fate of rimsulfuron, prosulfuron and oxasulfuron in soil type Calcic Chernozem Clayic.
Pachic (according to the FAO-WRB classification) were investigated using ultra-performance
liquid chromatography with diode array detection for herbicide detection. Their dissipation
behaviour in soil were evaluated under laboratory incubated condition at 70% water holding
capacity of soil and two temperature (25°C and 30°C) were maintained in termostat. In order
to investigate dissipation selected sulfonylureas were used as aqueous solution of commercial
formulation herbicides. The recommended dosage of rimsulfuron, prosulfuron and
oxasulfuron were 50, 20 and 80 g active ingredient (a.i.) per hectare, respectively.
Representative soil samples were collected after 2 hours, and then after 2, 6, 15, 30 and 50
days after the application of herbicides. Initial residues of all investigated herbicides were
higher at temperature 25°C than 30°C. The residues of rimsulfuron on both analysed
temperature for tested dose were less than LOQ (3.04 ug kg!) after 2 days and 6 days for
prosulfuron (2.97 yg kg!) and oxasulfuron (3.40 pg kg). The dissipation of this three
sulfonylureas in studied soil was described by using the Mittag-Leffler function ¢ E, (-bt).
Model coefficients a, b, c were received from the experimental data by using a fitting
procedure. Rimsulfuron and prosulfuron showed faster degradation in tested soil with half
lives of 0.49 and 0.03 days at temperature 30°C, respectively. The degradation rate of
oxasulfuron appeared something slower with half lives of 0.64 day at temperature 25°C.
These results indicate how herbicides belonging to the identical chemical class can behave in
various way concerning dissipation in soil.

AB  - The most important experimental parameters were investigated for chronopotentiometric
determination of imidacloprid using thin film antimony electrode as a working electrode. The
film of antimony was ex-sifu plated on the glassy carbon electrode. Britton-Robinson buffer
pH 10 was used as an optimal supporting electrolyte, where imidacloprid provided a well
define and reproductive reduction signal at the potential of -1100 mV (vs. Ag/AgCl, 3.5
mol/dm’* KCI). Based on the height and reproducibility of the analytical signal, initial potential
of -0.51 V was accepted as optimal, while selected optimal ranges of reduction current were
from -5 pA to -14.4 pA, and from -4.6 pA to -18.2 pA, for concentrations of 2 mg/dm” and 10
mg/dm°*, respectively. It was determined that analytical signal of imidacloprid decreased
exponentially with more negative values of reduction current. Before application of this
method to environmental samples. additional experiments related to method validation are
necessary.
