    Abstract Ethnopharmacological relevance: The polyherbal mixture made of Centaurium erythraea aerial parts and Cichorium intybus roots and Potentilla erecta rhizomes has been used for centuries to treat both the primary and secondary complications of diabetes.
    Aim of the study: As a continuation of our search for the most effective herbal mixture used as an ethnopharmacological remedy for diabetes, this study aimed to compare the in vitro biological activities of this polyherbal mixture and its individual ingredients, and, most importantly, to validate the ethnopharmacological value of the herbal mixture through evaluation of its phytochemical composition, its potential in vivo toxicity and its effect on diabetes complications.
    Materials and methods: Phytochemical analysis was performed using HPLC-UV. Antioxidant activity was estimated via the DPPH test. Potential cytotoxicity/anticytotoxicity was assessed using an in vitro RBCs antihemolytic assay and an in vivo sub-chronic oral toxicity method. Antidiabetic activity was evaluated using an in vitro α-amylase inhibition assay and in vivo using a chemically induced diabetic rat model.
    Results: The HPLC-UV analysis revealed the presence of p-hydroxybenzoic acid, p-hydroxybenzoic acid derivative, catechin, five catechin derivatives, epicatechin, isoquercetin, hyperoside, rutin, four quercetin derivatives, caffeic acid, and four caffeic acid derivatives in the polyherbal mixture decoction. Treatment with the decoction has shown no toxic effects. The antioxidant and cytoprotective activities of the polyherbal mixture were higher than the reference's ones. Its antidiabetic activity was high in both in vitro and in vivo studies. Fourteen days of treatment with the decoction (15 g/kg) completely normalized blood glucose levels of diabetic animals, while treatments with insulin and glimepiride only slightly lowered glycemic values. In addition, lipid status of treated animals as well as levels of serum AST, ALT, ALP, creatinine, urea and MDA were completely normalized. In addition, the polyherbal mixture completely restored the histopathological changes of the liver, kidneys and all four Cornu ammonis regions of the hippocampus.
    Conclusions: The polyherbal mixture was effective in the prevention of both primary and secondary diabetic complications such as hyperlipidemia, increased lipid peroxidation, non-alcoholic fatty liver disease, nephropathy and neurodegeneration.

    Abstract The amount of nineteen elements in eleven different lichen species, six fruticose (Bryoria capillaris, Bryoria fuscescens, Cladonia rangiformis, Ramalina capitata, Usnea chaetophora and Evernia prunastri) and five foliose (Hypogymnia tubulosa, Lobaria pulmonaria, Peltigera horizontalis, Umbilicaria cylindrica and Umbilicaria crustulosa) from five natural areas of the Balkan Peninsula (Serbia and Bulgaria) were determined by using inductively coupled plasma optical emission spectrometry (ICP-OES). Among macronutrients, the highest content was observed for Ca and K, while Mg and Na were represented in the smallest amount. Fe, Mn, Zn and Ba were the most abundant trace elements in contrast to Cd and Co, whose concentrationс wеre the lowest.

    Abstract In this study, we considered some pesticides as active substances within formulations for the protection of plant-based food in the Republic of Serbia in silico, because these pesticides have not often been investigated in this way previously, and in an analytical way, because there are not very many available fast, cheap, and easy methods for their determination in real agricultural samples. Seven pesticides were detected in selected agricultural products (tomatoes, cucumbers, peppers, and grapes) using the QuEChERS methodology and HPLC-DAD. Standard curves for the investigated pesticides (chlorantraniliprole, methomyl, metalaxyl, thiacloprid, acetamiprid, emamectin benzoate, and cymoxanil) show good linearity, with R

    Abstract In this study, we considered some pesticides as active substances within formulations for the protection of plant-based food in the Republic of Serbia in silico, because these pesticides have not often been investigated in this way previously, and in an analytical way, because there are not very many available fast, cheap, and easy methods for their determination in real agricultural samples. Seven pesticides were detected in selected agricultural products (tomatoes, cucumbers, peppers, and grapes) using the QuEChERS methodology and HPLC-DAD. Standard curves for the investigated pesticides (chlorantraniliprole, methomyl, metalaxyl, thiacloprid, acetamiprid, emamectin benzoate, and cymoxanil) show good linearity, with R 2 values from 0.9785 to 0.9996. The HPLC-DAD method is fast, and these pesticides can be determined in real spiked samples in less than 15 min. We further characterized the pesticides we found in food based on physicochemical properties and molecular descriptors to predict the absorption, distribution, metabolism, elimination, and toxicity (ADMET) of the compounds. We summarized the data supporting their effects on humans using various computational tools to determine their potential adverse effects. The results of our prediction study show that all of the selected pesticides considered in this study have good oral bioavailability, and those with high toxicity, therefore, could be harmful to human health. Chlorantraniliprole was shown in a molecular docking study as a good starting point for a new Alzheimer’s disease drug candidate.

    Abstract This study was designed to examine the effect of thermal treatment at different temperatures (70, 90 and 110 °C) over time (0–120 min) on the phenolic content and antioxidant activity of Myrtus communis L. ethanol extract in acetate buffer (pH = 3). Total phenols, flavonoids and proanthocyanidins contents and the radical scavenging activity, monitored during the treatment, were significantly influenced by the applied temperature (p < 0.05). The higher the temperature and the duration of the treatment, the greater the degradation and the loss of these compounds. Likewise, DPPH⋅ radical scavenging activity decreased, in a temperature-depending manner, during thermal treatment. Nonetheless, the results of the ABTS⋅⁺ test showed that the activity remained almost stable during the treatment. Furthermore, the kinetics of degradation of compounds analysed by HPLC-DAD, namely myricetin-3-O-galactoside, quercetin-3-O-glucoside and quercetin-3-O-rhamnoside was investigated and their energy of activation was determined. Degradation rate in case of quercetin-3-O-rhamnoside was the most sensitive to temperature (20.536 kJ/mol) followed by myricetin-3-O-galactoside (12.268 kJ/mol) and quercetin-3-O-glucoside (2.838 kJ/mol). The use of the discriminant analysis has shown that some other factors other than temperature and time of thermal treatment might also have a minor influence on the content of total phenolics, total flavonoids, proanthocyanidins and values of the antioxidant tests (DPPH⋅, ABTS⋅⁺) in the investigated extracts of M. communis L.

    Abstract This study presents chemical profiles, antimicrobial and toxicological evaluation of the essential oils (EOs) of five Achillea species native to the flora of Serbia (A. coarctata, A. chrysocoma, A. clypeolata, A. pseudopectinata and A. ageratifolia). The chemical compositions of the EOs were investigated by Gas Chromatography/Mass Spectrometry and Gas Chromatography/Flame Ionization Detector analyses. The microdilution method was used for antimicrobial and Artemia salina acute toxicity bioassay for toxicological evaluation of the EOs. Oxygenated monoterpenes have shown dominance in four out of five tested EOs (A. ageratifolia, A. pseudopectinata, A. chrysocoma and A. clypeolata) where 1,8-cineole and camphor were the most common dominant compounds. Conversely, A. coarctata EO was characterized by dominance of oxygenated sesquiterpenes with viridiflorol and cis-cadin-4-en-7-ol as the major compounds. Antimicrobial testing showed that studied EOs are characterized by broad-spectrum antimicrobial activity, which was not notably selective in relation to the Gram-staining properties of the tested microorganisms. Furthermore, all five EOs have shown high toxicity in A. salina lethality bioassay, suggesting that they may possess a certain level of pesticidal and/or antitumor properties. Achillea chrysocoma EO demonstrated the most prominent antimicrobial activity, but it was the fourth active in view of toxicity against A. salina. Contrary, A. coarctata EO was the most potent toxic agent toward A. salina, but it was only the fourth of the five regarding the antimicrobial potential. Presented results confirmed that highly toxic EOs could demonstrate moderate activity against the pathogenic microorganisms as the effects of the EOs diverge in pro- and eukaryotic cells.

    Abstract Introduction. Dry eye is a multi-factorial disease of tears and ocular surface resulting in symptoms of discomforts, vision disabilities, unstable tear film and possible damage to the ocular surface. The final diagnosis of dry eye results from collecting various data obtained in the course of several diagnostic procedures. Dry eye - diagnostic methods. Diagnosis of dry eye involves performing a series of clinical methods and laboratory tests. This paper presents some of the procedures used in the diagnosis of dry eye. Biomicroscopy of the eye with objective tests to check the tear film (Schirmer I, rose bengal, time break up precorneal tear film), verification of corneal sensitivity and impression cytology of the conjunctiva, are the optimum dry eye diagnostic routine procedures. Conclusion. The combination of clinical and histopathological methods of examination of the anterior ocular surface is the basis for a quality and precise diagnosis of dry eye.

    Abstract This is the first comparative study on antimicrobial activity of essential oils (EOs) of six Achillea species (A. crithmifolia, A. distans, A. grandifolia, A. millefolium, A. nobilis, and A. lingulata) against ATCC and clinical microbial strains isolated from human swabs and on their toxicological potential on crustaceans. Oxygenated monoterpenes represented the major compound class in all six EOs, ranging from around 50 % (A. millefolium, A. nobilis, and A. lingulata) up to over 80 % (A. crithmifolia and A. grandifolia). Specific phytochemical profiles of the major volatiles were determined for each species. Still, borneol was the dominant compound in EOs of three yarrow species: A. distans, A. lingulata, and A. millefolium. Other major compounds were 1,8-cineole in A. crithmifolia, camphor in A. grandifolia, and artemisia ketone in A. nobilis EO. Antimicrobial activities of EOs were examined by a microdilution method revealing inhibitory action against all 15 studied strains in the range of 0.07-20.00 mg/mL (MICs). High toxicity (LC

    Abstract This study reports the effect of an acetone extract of Evernia prunastri on the micronucleus distribution of human lymphocytes and effect on cholinesterase activity. Furthermore, the antioxidant activity (estimated via DPPH, ABTS, TRP and CUPRAC assays), as well as total phenolic compounds (TPC) and antibacterial activity (against two Gram-positive and three Gram-negative bacteria) were determined. Chemical profiling of four E. prunastri extracts (acetone, diethyl ether, ethyl acetate and dichloromethane) was realized by GC–MS and HPLC analysis. In addition, the activity concentrations of 40K, 137Cs, 226Ra and 232Th were established.
