AB  - Varroa destructor is a parasitic mite responsible for the loss of honey bee (Apis mellifera) colonies. This study aimed to find a promising marker in honey for the bee colony infestation level using fluorescence spectroscopy and biochemical analyses. We examined whether the parameters of the honey samples’ fluorescence spectra and biochemical parameters, both related to proteins and phenolics, may be connected with the level of honey bee colonies’ infestation. The infestation level was highly positively correlated with the catalase activity in honey (r = 0.936). Additionally, the infestation level was positively correlated with the phenolic spectral component (r = 0.656), which was tentatively related to the phenolics in honey. No correlation was found between the diastase activity in honey and the colonies’ infestation level. The results indicate that the catalase activity in honey and the PFC1 spectral component may be reliable markers for the V. destructor infestation level of the colonies. The obtained data may be related to the honey yield obtained from the apiaries. © 2023 by the authors.

AB  - Strawberries are an important fruit in the European diet because of their unique taste and high content of essential nutrients and bioactive compounds. The anthocyanins are known to be colorful phenolics in strawberries. In 17 samples of six strawberry cultivars produced in Serbia, i.e., the common varieties Alba, Asia, and Clery as well as promising breeding materials (11.29.11, 11.34.6, and 11.39.3), the anthocyanin profile as well as antimicrobial and antioxidative activity profiles were determined. All investigated extracts showed antioxidative and antibacterial activities against Gram-negative Aliivibrio fischeri. The responses were quite similar in number and intensity. The HPTLC-DPPH• scavenging assay and HPTLC-Aliivibrio fischeri bioassay coupled with high-resolution mass spectrometry identified pelargonidin-3-O-glucoside (Pg-3-glc) as the main anthocyanin and prominent antioxidative and antimicrobial compound in strawberries. The density functional theory calculations at the M06-2X/6-31+G(d,p) level showed that Pg-3-glc quenches free radicals via sequential proton loss electron transfer mechanism in water and in pentyl ethanoate, where the 5-OH group is the most reactive site for proton and hydrogen atom transfer. The results were confirmed via spectrophotometry. The highest total phenolic content was found in Clery and 11.39.3, while statistically significant differences between the genotypes regarding the antioxidant activity were not confirmed. Although very similar in the anthocyanin, antioxidative, and antimicrobial profile patterns, the strawberry genotypes were successfully classified using principal component analysis.

AB  - Research background. Considering the importance of consumption of berry fruits with
proven health-beneficial properties and difficulties in quality control of products of specific botanical and geographic origin, a fingerprint method was developed, based on advanced data analysis (pattern recognition, classification), in order to relate the variability
of nutrients in the selected cultivars to primary metabolite profile.
Experimental approach. Forty-five samples of genuine berry fruit cultivars (strawberry,
raspberry, blackberry, black currant, blueberry, gooseberry, chokeberry, cape gooseberry
and goji berry) were characterized according to chromatographic profiles of primary metabolites (sugars, lipids and fatty acids) obtained by three chromatographic techniques
(high-performance thin-layer chromatography, gas chromatography coupled to mass
spectrometry, and high-performance anion-exchange chromatography with pulsed amperometric detection).
Results and conclusions. Comprehensive analysis allowed monitoring and identification
of metabolites belonging to polar lipids, mono-, di- and triacylglycerols, free fatty acids,
free sterols, sterol esters, mono- to heptasaccharides and sugar alcohols. Chemical fingerprint of berry seeds showed the uniformity of primary metabolites within each fruit species, but revealed differences depending on the botanical origin. All three chromatographic methods provided a discriminative, informative and predictive metabolomics
methodology, which proved to be useful for chemotaxonomic classification.
Novelty and scientific contribution. A novel methodology for the identification of bioactive compounds from primary metabolites of natural products was described. The proposed untargeted metabolite profiling approach could be used in the future as a routine
method for tracing of novel bioactive compounds. The knowledge of metabolite composition obtained in this study can provide a better assessment of genotypic and phenotypic differences between berry fruit species and varieties, and could contribute to the development of new breeding programs.

AB  - The effects of organic versus integral and conventional crop management on content and distribution of major and trace elements in different varieties of potato were investigated in a three year field trial. A set of 48 potato tubers of four varieties with different harvesting times, cultivated in three types of agricultural systems: conventional (C), integral (I), and organic (O) were characterized based on the composition of the elements of their bulk and peel. A total of 16 elements were quantified. In order to determine the source of variation among the types of production, parts of potato and varieties, multivariate analysis of variance (MANOVA) was conducted. The results indicate that Ca, Mg, and K may be considered as important indicators of the type of production, genotypes of potato, and harvesting time. Additionally, the analyses show that ten microelements are able to distinguish between production types and genotypes of potato.

AB  - This research proposes a new way of tracing differences between potato cultivation systems, botanical origin, and climate conditions by using sugar profiles. A set of 90 potato tubers of four varieties with different ripening times, cultivated in three types of agricultural systems: conventional (C), integral (I), and organic (0) were characterized based on sugar profiles of their bulk and peel. A total of nineteen sugars were quantified. In order to determine the source of variation among the types of production, the years of production and varieties, multivariate analysis of variance (MANOVA) was conducted. The results indicated that starch may be considered an important indicator of the type of production, botanical origin, and ripening time. Additionally, the analyses showed that sugar macro and microcomponents such as fructose, glucose, saccharose, sorbitol, trehalose, arabinose, turanose and maltose were the main factors for the differentiation of production types, production years and botanical origin of potato.

AB  - IntroductionPropolis is a resinous natural substance collected by honeybees from different plant sources. Due to the presence of various phytochemicals, this bee-product exhibits numerous biological activities, including anti-bacterial, anti-viral, anti-inflammatory, anti-oxidant, immunostimulating and anti-tumour effects. As the chemical composition and biological activity of propolis depend on its botanical and geographical origin, searching for new bioactive substances in various types of propolis from unexplored regions is of great importance. ObjectiveThe aim of this study is the evaluation of the phenolic profile of poplar propolis samples in order to characterise Serbian propolis, to identify possible new constituents and to specify the phenolic components relevant for differentiation of poplar propolis samples into two subgroups through simultaneous analysis of poplar bud extracts. MethodsEthanolic extracts of propolis and poplar buds were comprehensively analysed using ultrahigh-performance liquid chromatography coupled with hybrid mass spectrometry, which combines the linear trap quadrupole and Orbitrap MS/MS mass analyser together with chemometric methods. ResultsExtensive fingerprint analysis of Serbian propolis was achieved for the first time. Seventy-five phenolic compounds were detected. Eight of them were identified in propolis for the first time. Pattern-recognition methods applied to the content of ten quantified phenolics verified the existence of two subgroups of propolis, with galangin, chrysin and pinocembrin as the most influential distinguishing factors. ConclusionThe phenolic composition of the analysed propolis samples confirm their affiliation to the European poplar type propolis and the existence of two subgroups according to botanical origin.

AB  - GIS is a computer-based system to input, store, manipulate, analyze and output spatially referenced data. There is a huge range application of GIS that generally sets out to fulfill: mapping, measurement, monitoring, modeling and management. In this study, GIS technology was used for the regional recognition of origin and distribution patterns of multifloral honey chemical traits in Serbia. This included organizing and analyzing the spatial and attributive data of 164 honey samples collected from different regions of Serbia during the harvesting season of 2009. Multifloral honey was characterized in regards to mineral composition, sugar content and basic physicochemical properties. The kriging method of Geostatistical Analyst was used for interpolation to predict values of a sampled variable over the whole territory of Serbia

AB  - Multifloral honey was characterized in regards mineral to composition, sugar content and basic physicochemical properties. A total of 164 honey samples were collected from different regions of Serbia during the harvesting season 2009. Univariate data analysis (descriptive statistics and analysis of variance), geographic information system and pattern recognition methods (principal component analysis and cluster analysis) were utilized in order to identify the geographical origin of honey. The content of Mg, K, and Cu, electrical conductivity and optical rotation were established as useful indicators in tracing regional differences between honey samples. Samples originating from Zlatibor region were clearly distinguished from those from the rest of Serbia, showing higher K and Mg contents, as well as higher values of optical rotation, electrical conductivity, and free acidity. The influence of the soil composition, and climate conditions, as well as the presence of particular flora on the honey composition is emphasized. The modeling of the geographic origin of honey was attempted by means of linear discriminant analysis. .
AB  - Karakterizacija polifloralnih medova u pogledu mineralnog sastava, sadržaja šećera i osnovnih fizičko-hemijskih parametara izvršena je na osnovu analize 164 uzorka iz različitih regiona Srbije sakupljenih tokom 2009. godine. Univarijantna analiza podataka (deskriptivna statistika i analiza varijanse), zajedno sa geografskim informacionim sistemom i multivarijantnom hemometrijskom analizom (analiza glavnih komponenata i klasterska analiza) primenjene su u cilju određivanja geografskog porekla meda. Utvrđeno je da su sadržaj Mg, K i Cu, električna provodljivost i optička rotacija parametri koji ukazuju na razlike u regionalnom poreklu meda. Uzorci koji potiču iz zlatiborskog regiona su se jasno razdvojili od uzoraka iz ostalih delova Srbije na osnovu većeg sadržaja K i Mg, kao i većih vrednosti optičke rotacije, električne provodljivosti i slobodne kiselosti. Ukazano je na uticaj sastava zemljišta, klimatskih uslova i postojanja endemičnih vrsta na sastav meda. Modelovanje geografskog porekla meda je urađeno primenom linearne diskriminantne analize. .
