AB  - Persian walnut (or English walnut) growing dates back to 7000 BC in Persia, a gene center of Juglans regia L. The top leading countries in walnut production are China, the USA, and Iran accounting for ~75% of world production. Nuts are an essential component in human nutrition because their consumption provides the required amount of energy (720 kcal per 100 g of fruits), unsaturated fatty acids, carbohydrates, proteins, fibers, sterols, tocopherols, minerals (K, P, Ca, Mg, and Na), volatiles, and other bioactive constituents. In addition, walnut kernels are rich in oil (50–70%) and protein, depending on the cultivar, location, and irrigation rate. Although mostly consumed raw, walnut kernels are increasingly processed by cold pressing into light yellow edible oil used in foods as flavoring, like salad dressings or cooking. Walnut oil is especially valued for its high content of essential fatty acids (linoleic and linolenic acids) and micronutrients such as phytosterols, squalene, and other tree nut oils polyphenols, and tocopherols. As by-products, both shell and cold-pressed cake from walnut that remains after the cold pressing process of oil can be used in various ways (food, cosmetics, pharmaceutical products, or textile industry). Especially residual walnut press cake is practical when used in food and in pharmacy, mostly integrated into other products. The reason for treating residual cake as a value-added product lies in the fact that defatted cake is generally rich in polar phenolic compounds and, as a source of natural antioxidants, is expected to show significant antioxidant activity. The most abundant polyphenols found in walnut oil cake are hydrolyzable tannins. In addition, press cake is rich in dietary fiber, protein, residual oil, polyunsaturated fatty acids, and tocopherol, all considered health-enhancing components. Therefore, by using walnut oil cake as a low-cost product, many aspects connected with the valorization of food wastes are covered, such as consumers' dietary habits, economy, and environmental protection. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.

AB  - The aim of this study was to find the chemical parameters for the differentiation of plum cultivars grown along the fjord areas of Western Norway and Eastern Norway, having specific agroclimatic conditions. Chemical analysis of the fruits confirmed the contents of 13 quantified elements, 22 sugar compounds, 11 organic acids, 19 phenolic compounds, and antioxidant activity in 68 plum cultivars. Dominated contents were noted for nitrogen (with the maximum mean value of 3.11%), potassium (8055.80 mg/kg), and phosphorous (7878.88 mg/kg). Averagely, the highest level of sugars was determined for glucose (244.46 g/kg), fructose (197.92 g/kg), sucrose (208.25 g/kg), and sorbitol (98.02 g/kg), organic acids for malic acid (24.06 g/kg), and for polyphenol compounds were 5-O-caffeoylquinic acid (66.31 mg/kg), and rutin (58.06 mg/kg). Applied principal component analysis has been useful for distinguishing the plum cultivars from three areas in Norway where copper, iron, potassium, magnesium, manganese, and sodium; sucrose, ribose, maltose, and raffinose; p-hydroxybenzoic acid, rutin, ferulic acid, kaempferol 7-O-glucoside, p-coumaric acid, and 5-O-caffeoylquinic acid were the most influential. In regard to human health and future breeding work that will have the aim to produce functional food with high health-related compounds, the plum cultivar ‘Mallard’ should be underlined due to the high level of elements, ‘Valor’ due to high sugar content, ‘Helgøyplomme’ due to content of organic acids, and ‘Diamond’ due to the content of phenolic compounds. © 2023 by the authors.

AB  - Viticulture is of great economic importance in the southern part of Bosnia and Herzegovina, thanks to favorable climatic conditions and a long-standing tradition of growing vines. The assortment is dominated by international varieties, as well as some autochthonous and domesticated varieties. The subject of the research is the analysis of the quality of Cabernet Sauvignon, Merlot, Vranac, and Blatina varieties at two localities in Herzegovina during the period 2020–2021. The paper examined the most important economic and technological characteristics, grape quality, and berry phenolic profile. A particularly pronounced variation of the tested characteristics during the research period was observed in the Merlot and Blatina varieties, while the Cabernet Sauvignon and Vranac varieties showed a slightly higher stability of the tested characteristics. Poorer grape quality during the research period was registered with the Blatina variety, which can be considered a varietal characteristic to some extent. The analyzed grape varieties were rich in polyphenols, and the impact of grape variety on the berry phenolic profiles was confirmed. The most abundant polyphenols in the analyzed grape samples were quercetin 3-O-glucoside and catechin gallate, followed by kaempferol 3-O-glucoside. The highest values of polyphenols were found mainly in the samples originating from Trebinje. Indigenous Balkan grape varieties (Vranac and Blatina) stood out with particularly high contents of some phenolics. Research has shown that climatic conditions have a significant influence on the most important characteristics of grapes, which are conditioned by genotypic specificities. The conditions for growing vines in the conditions of Herzegovina enable high quality in the production of grapes, especially the Cabernet Sauvignon and Vranac varieties. The autochthonous variety Blatina shows significant variations in grape quality during the test period, which was confirmed by the results of a larger number of studies in the previous period. © 2023 by the authors.

AB  - The Zn(II) complexes [Zn(HLSe2)2](NO3)2∙CH3OH (2-NO3-Se) and [Zn(HLSe3)2](NO3)2·DMF (3-NO3-Se) with selenazolyl-hydrazone ligands 4-(4-methoxyphenyl)-2-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3-selenazole (HLSe2) and 4-(4-methylphenyl)-2-(2-(pyridin-2-ylmethylene)hydrazinyl)-1,3-selenazole (HLSe3) have been synthesized and characterized using singe crystal X-ray diffraction analysis. Antiproliferative activities of 2-NO3-Se and 3-NO3-Se, the corresponding ligands and sulphur isosteres of the complexes and the ligands were determined on non-malignant HTR-8/SVneo extravillous trophoblast cell line and malignant JEG-3 and JAr choriocarcinoma cell lines. All Zn complexes exhibited cytotoxic effect, comparable to that of a reference metal-based drug, cisplatin. The antioxidant activity of all compounds was determined in three antioxidant assays: ORAC (Oxygen Radical Absorbance Capacity), ABTS [(2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt] and CERAC [Ce(IV)-based reducing capacity]. As a result of synergy between Zn(II) and selenazolyl-hydrazone ligands, the complexes 2-NO3-Se and 3-NO3-Se appeared to be more active than Trolox, which is not the case for their sulfur counterparts. In-silico calculations of ADME properties pointed that the compounds possess some of desirable Lipinski rule principles. Applied algorithms did not report the compounds as potential PAINS or covalent inhibitors, although due to high molecular weight none of the compounds represent a potential lead compound. Toxicity prediction of the compounds is performed using machine learning models. The complexation of the ligands most likely reduces their toxicity or reduces their negative metabolic effects. © 2023 Elsevier B.V.

AB  - Previously, the cytotoxic actions of five Pd(II) complexes with bidentate N-heteroaromatic chelators (complexes 1–5) on a palette of several cancer cell lines were investigated. However, the results of the cytotoxic activity did not correlate with the hydrophobic character of the complexes. To gain further insight into the structure–activity relationship, essential for the design of novel potential drugs, other factors, such as non-specific interactions with cellular proteins, have to be taken into account. To explore the potential non-specific influence of the complexes on protein structures, ovalbumin (OVA) was chosen as a model system to mimic cellular non-specific crowding environments with high protein concentrations. A Fourier-transform infrared spectroscopy study implied that the binding of 3 and 4 led to only moderate alternations in the secondary structures of the protein, without the possibility to penetrate into hydrophobic core of the protein and disruption of protein native fold. Contrary, the effect of complex 5 on OVA secondary structures was concentration-dependent. While the lower concentration of complex 5 had no effect on OVA structure, a doubled concentration of complex 5 led to complete disruption of the content native-like secondary structures. The concentration-dependent effect of complex 5 on the changes in secondary structures and considerable increase in the exposure of OVA hydrophobic surfaces to water may be related to a potential crosslinking that leads to OVA aggregation. © 2022 Serbian Chemical Society.

AB  - The variety Prokupac is the dominant variety in the vineyards of Southern Serbia, which produces quality wines of characteristic and unique tastes. In the agroecological conditions of the Prokuplje vine district, the influence of manual defoliation on the phenolic profile of the wine produced from the variety Prokupac was examined. Four experimental treatments with different timings of manual defoliation were applied: early defoliation—treatment I, early defoliation— treatment II, late defoliation—treatment III and the control. The phenolic profile of the wine was determined for the three treatments of defoliation and the control treatment. Additionally, a multivariate analysis was applied on the obtained results, together with already published data (grape seeds and skins phenolic profiles). Identification and quantification of the phenolic compounds was performed using ultra-high-performance liquid chromatography (UHPLC) with an ultraviolet multi-diode detector (DAD) and mass detector with three analyzers—triple quadrupole (QQQ). Based on the obtained results, it was determined that there are significant differences between the experimental treatments in the content of individual polyphenols, total polyphenols and the antioxidant capacity. Twenty (20) phenolic compounds were identified in the wine samples of the experimental treatments. Defoliation significantly affected the variations of the contents of phenolic acids and flavonoids. In treatment III, the highest content of gallic acid was obtained, while the treatments with early defoliation did not differ in relation to the control sample. Early defoliation in treatments I and II had an effect on the phenolic composition of the wine by favoring the accumulation of flavonol, while the content of hydroxycinnamic acid and total anthocyanins (TAC) was higher in treatment III. The TAC increases with later defoliation. The wines obtained by the defoliation treatments did not show higher antioxidant activity compared to the control sample. A principal component analysis resulted in clustering of the samples based on the phenolic components characteristic for each group of samples.

AB  - The aim of this study was to compare total phenolic content (TPC), radical-scavenging activity (RSA), total anthocyanin content (TAC), sugar and polyphenolic profiles of two apple cultivars (‘Discovery’ and ‘Red Aroma Orelind’) from organic and integrated production systems in climatic conditions of Western Norway. Sixteen sugars and four sugar alcohols and 19 polyphenols were found in the peel, but less polyphenols were detected in the pulp. The peel of both apples and in both production systems had significantly higher TPC and RSA than the pulp. The peel from integrated apples had higher TPC than the peel from organic apples, while organic apples had higher TAC than the integrated. Sucrose and glucose levels were higher in organic apples; fructose was cultivar dependent while minor sugars were higher in integrated fruits. The most abundant polyphenolic compound in the peel of the tested cultivars was quercetin 3-O-galactoside, while chlorogenic acid was most abundant in the pulp. Regarding polyphenols, phloretin, phloridzin, protocatechuic acid, baicalein and naringenin were higher in organic apple, while quercetin 3-O-galactoside, kaempferol 3-O-glucoside, chlorogenic acid and syringic acid was higher in integrated fruits. In conclusion, organic ‘Discovery’ and integrated ‘Red Aroma Orelind’ had higher bioavailability of health related compounds from the peel and the pulp.

AB  - Abstract: Nickel ferrite nanoparticles were synthesized via thermal decomposition of β-diketonato complexes of nickel(II) and iron(III). The mechano-chemical activation of the complex precursors was used to ensure the increase in the reaction activity and consequently reduce thermal decomposition temperature. The prepared sample was thoroughly characterized by X-ray powder diffraction, FT-IR spectroscopy, scanning electron microscopy (SEM) coupled with electron dispersive spectroscopy (EDS), and transmission electron microscopy (TEM). X-ray powder diffraction and FT-IR confirmed the spinel phase of the investigated powder. SEM and TEM revealed the ultrafine nature of nanosized polygonal particles, with a pronounced agglomeration effect. The capacity for electrocatalytic applications was examined using cyclic voltammetry (CV) and electrical impedance spectroscopy (EIS). Electrocatalytic measurements pointed out that the addition of 5% of nickel ferrite as a modifier to carbon paste electrode caused a current increase and a decrease of the EIS semicircle. Further increase in the amount of the modifier decreased heterogeneity of the electrode surface and served as excellent sensor for the detection of gallic acid in the concentration range from 1 to 10 µM with the detection limit of 0.27 µM. This unambiguously indicated the significant improvement in electrode transfer rate and better characteristics of the diffusion layer. © 2022, Pleiades Publishing, Ltd.

AB  - Domesticated international (standard) apple cultivars, together with resistant apple cultivars are the core of the Serbian apple production. Furthermore, autochthonous cultivars are characterized by a good adaptability to the local environmental conditions and represent a valuable source of genetic variability, as well as an important source of the gene pool for further breeding programs. Additionally, they show a higher phenolic content and a stronger antioxidant activity, in comparison to commercial cultivars. Therefore, they are more likely to be used as a functional food. The subjects of this study were seventeen samples of fruits and leaves from autochthonous apple cultivars, five international standard cultivars, and six resistant apple cultivars. The phenolic profile was determined using ultra-high performance liquid chromatography (UHPLC), coupled with a diode array detector and a TSQ Quantum Access Max triple-quadrupole mass spectrometer. A total of twenty compounds were quantified in the samples. Most of the analyzed phenolics were detected in higher amounts in the peel, compared to the mesocarp. The results of the multivariate analysis of variance (MANOVA) indicate that 5-O-caffeoylquinic acid is present in the highest amount in the mesocarp, while in the peel and leaves, quercetin-glycosides were detected in the highest amount. According to the MANOVA: phloretin, phlorizin, 5-O-caffeoylquinic acid, kaempferol, and p-coumaric acid are present in significantly higher levels in the autochthonous cultivars, compared to the standard and resistant ones (in both fruits and leaves). Therefore, these compounds can be used as chemical tracers of the apple varietal origin. © 2022 by the authors.

AB  - Blueberries, which are recognized by their colored fruits and exquisite flavor and taste, are a great source of bioactive substances with potential functional properties. For the purpose of this study, the blueberry cultivars ‘Duke’, ‘Chandler’ and ‘Bluecrop’ were picked at four different times. The aim of the study was to compare the cultivars and determine the best time for picking fruits for table consumption and to produce berries that can be used as functional foods with elevated levels of bioactive compounds. According to principal component analysis (PCA), the most influential traits for distinguishing different times of harvest in the ‘Duke’ cultivar were sorbitol, glucose, sucrose, and turanose; for the cultivar ‘Chandler’, they were caffeic acid, aesculetin, and quercetin; for the ‘Bluecrop’, they were fructose, maltose, radical scavenging activity, and quercetin. Blueberry fruits aimed for table consumption were those harvested in the first two pickings of the cultivar ‘Duke’, in the first and third of the ‘Bluecrop’, and in the third picking time of the cultivar ‘Chandler’, due to the highest fruit size and very high level of sugar (mostly glucose and fructose). ‘Duke’ berries from the second and third harvest (high level of total phenolic content, radical scavenging activity, total anthocyanins, aesculin, quercetin, and isorhamnetin), ‘Chandler’ from the first and third (the highest p-hydroxybenzoic acid, aesculetin, caffeic acid, phloridzin, kaempferol, kaempferol 3-O-glucoside, quercetin 3-O-rhamnoside, rutin, and quercetin) and ‘Bluecrop’ from the third harvest (highest level of total phenolics, radical scavenging activity, quercetin, rutin, quercetin 3-O-glucoside, kaempferol, quercetin 3-O-rhamnoside, kaempferol 3-O-glucoside, and isorhamnetin) had the highest levels of health-promoting compounds. © 2022 by the authors.

Metals, sugars, organic acids, antioxidant tests, and polyphenol content have been observed. In all investigated samples, the most dominant sugars were glucose, fructose, and sucrose. Among 11 tested organic acids, the dominant was malic acid, followed by citric and maleic acid. The most common metal was potassium, followed by magnesium and zinc. The quantification of polyphenols showed that among the 11 quantified polyphenols, chlorogenic acid, quercetin 3-O-rhamnoside, quercetin 3-O-glucoside, quercetin, and phlorizin were the most abundant. A detailed study of the polyphenolic profile of nine investigated apple samples provided 30 identified polyphenolic compounds from the class of hydroxybenzoic and hydroxycinnamic acids, flavonoids, and dihydrochalcones. In addition to the identified 3-O-caffeoylquinic acid, its two isomers of 5-O-caffeoylquinic acid and three esters were also found. Present polyphenols of the tested apples provided significant data on the quality of Norwegian apples, and they contribute to the distinguishing of these apple samples.

AB  - To evaluate the impact of chalcogen atom type, we performed a comparative study of antioxidant capacity and antiproliferative activity of a focused library of three pyridine-based hydrazonyl-1,3-selenazoles and their sulfur isosteres in five antioxidant assays and in six human solid tumor cell lines, respectively. In-silico calculations were further used to check pharmacokinetic profiles of investigated compounds such as drug-likeness parameters and interaction with water. Generally, selenium compounds appear to be more potent in comparison to sulfur isosteres in the performed essays.

AB  - Solid-state reaction between BaTiO3and Fe2O3was used to produce a multiferroic heterostructure composite. Commercial BaTiO3and Fe(NO3)3•9H2O were suspended in ethanol for 30 minutes in an ultrasound bath. The prepared mixture was thermally processed at 300°C for 6 h. Sintering at 1300 °C for 1 h resulted in a mixture of different phases, BaTiO3, BaFe12O19and Ba12Ti28Fe15O84, which were confirmed by x-ray powder diffraction. A dense microstructure with a small volume fraction of closed porosity was indicated by the scanning electron microscopy, while a homogeneous distribution of Fe ions over BaTiO3phase was visible from energy dispersive spectroscopy mapping. Doping of BaTiO3with Fe2O3resulted in formation of magnetic hexaferrite phases, as confirmed by dielectric measurements that showed a broadened maximum of the permittivity measured as a function of temperature.

AB  - The aim of this study was to provide information on the phenolic and sugar profiles of different parts of the buckwheat plant, which can define that buckwheat is a functional food, with a high nutritional value and very useful for human health. Therefore, the extracts of buckwheat leaf, stem, and flower, as well as buckwheat grain were analysed for the content of polyphenol and antioxidant tests. The identification of a notable number of phenolic compounds and quantification of sugars in different parts of buckwheat indicates that buckwheat is a highly valuable plant. A total of 60 phenolic compounds were identified (18 cinnamic acid derivatives, 14 flavonols, 13 flavan-3-ols (including proanthocyanidins), 10 hydroxybenzoic acid derivatives, and 5 flavones) using ultra-high-performance liquid chromatography (UHPLC), coupled with a hybrid mass spectrometer which combines the Linear Trap Quadrupole (LTQ) and OrbiTrap mass analyzer. The highest number of phenolic compounds was found in the analysed buckwheat flower sample, and then in the leaf, followed by the grain and the stem. In addition, the sugar profile of buckwheat leaf, stem, flower and grain, as well as the buckwheat pollen and the nectar was analysed. Hence, 16 sugars and 5 sugar alcohols were detected by the high-performance anion exchange chromatography (HPAEC) with a pulsed amperometric detector (PAD). Sucrose was found in a significant amount with the highest content in buckwheat leaf. Trisaccharides had similar accumulation in the sample extracts, while disaccharides dominated in buckwheat leaf, followed by nectar and pollen. The sugar alcohols showed the highest content in buckwheat grain, where erythritol was predominant. The obtained results show that buckwheat is very rich in phenolic compounds and sugars. In addition to grain, the other parts of the buckwheat plant can be used as a very good source of different classes of phenolic compounds. This study provides useful information on the distribution of phytochemicals in different parts of the buckwheat plant, which contribute to the maintaining of the status of buckwheat as a functional food.

AB  - In this study we synthesized a series of sixteen bis(imino)pyridines (BIPs) starting from 2,6-diaminopyridine and various aromatic aldehydes, and evaluated their antioxidant, antibacterial, antifungal and acetylcholinesterase (AChE) inhibitory activity. The chemical structures were elucidated by FTIR, elemental analysis, ESR and HRMS. H-1 and C-13 NMR spectra couldn't be acquired due to the formation of stable, carbon-centered radical cations in a solution, as confirmed by ESR spectroscopy and DFT calculations. The in vitro antioxidant potency was evaluated using four assays: free radical scavenging activity (DPPH and ABTS), reducing power and total antioxidant capacity assay. BIPs demonstrated excellent antioxidant properties, and two derivatives proved to be more potent than reference antioxidants (ascorbic acid and Trolox) in all assays. DFT calculations on.B97XD/6-311++g(d,p) level of theory provided valuable insights into the radical scavenging mechanism of BIPs. For hydroxyl-substituted BIPs, hydrogen atom transfer (HAT) is a predominant mechanism, while the single electron transfer coupled with proton transfer (SET-PT) governs the antioxidant activity of other derivatives. Intramolecular hydrogen bonding (IHB) plays an important role in the mechanism of antioxidant activity as revealed by noncovalent interaction analysis and rotational barrier calculations. The spin density of radical cations is localized on carbon atoms of a pyridine ring, which corroborates with g-factors and multiplicity obtained from ESR analysis. The most potent BIP exhibited moderate inhibitory activity toward AChE (IC50 = 20 +/- 4 mu M), while molecular docking suggested binding at the peripheral anionic site of AChE with the MMFF94 binding enthalpy of -43.4 kcal/mol. Moderate in vitro antimicrobial activity of BIPs have been determined against several pathogenic bacterial strains: Pseudomonas aeruginosa, Escherichia coli, Enterococcus faecalis, Staphylococcus aureus and clinical isolate of methicillin resistant S. aureus (MRSA). The antifungal activity of BIPs toward Candida albicans was also confirmed. The similarity ensemble approach combined with molecular docking suggested leucyl aminopeptidase as the probable antimicrobial target for the three most potent BIP derivatives.

AB  - This paper presents the chemical composition of the fruits of three European plum cultivars ('Cacanska Rana', 'Cacanska Lepotica', and 'Cacanska Najbolja') grafted on four rootstocks (Myrobalan, 'Pixy', Fereley', and 'St Julien A'). The rootstock/cultivar combinations significantly influenced the content of most of the phenolic compounds in the plum skin and flesh. The total anthocyanin content in the skin ranged from 1.87 to 7.33 mg cyanidin-3-glucoside g(-1) fresh weight. The major phenolic compound in the skin was rutin, which ranged from 95 to 238 mg kg(-1), while in the flesh, cinnamic acid and catechin were dominant. The total sugar content in the fruit ranged from 66.2-147 mg g(-1). The highest glucose and fructose contents were in `Cacanska Lepotica', then in `Cacanska Najbolja', and the lowest were in `Cacanska Rana' cultivar. The highest contents of glucose and sucrose were found in fruits from trees grafted on Myrobalan rootstock, and the lowest in fruits from trees grafted on 'St Julien A' rootstock. The rootstocks significantly influenced the potassium, calcium, and copper contents in the plum fruit. The results of this study demonstrate the significant effect of rootstocks on the phenolic and sugar profiles, and on the mineral content of the plum fruits.

The highest glucose and fructose contents were in `Cacanska Lepotica', then in `Cacanska Najbolja', and the lowest were in `Cacanska Rana' cultivar. The highest contents of glucose and sucrose were found in fruits from trees grafted on Myrobalan rootstock, and the lowest in fruits from trees grafted on 'St Julien A' rootstock. The rootstocks significantly influenced the potassium, calcium, and copper contents in the plum fruit. The results of this study demonstrate the significant effect of rootstocks on the phenolic and sugar profiles, and on the mineral content of the plum fruits.",
