  • Functional Teas from Penthorum chinense Pursh Alleviates Ethanol-Induced
           Hepatic Oxidative Stress and Autophagy Impairment in Zebrafish via
           Modulating the AMPK/p62/Nrf2/mTOR Signaling Axis

    • Free pre-print version: Loading...

      Abstract: Abstract Penthorum chinense Pursh (PCP), a medicinal and edible plant, is widely used in many clinical liver diseases. Oxidative stress and autophagy impairment play crucial roles in the pathophysiology of alcoholic liver disease (ALD). Therefore, the aim of this study was to elucidate the mechanism of PCP in attenuating ethanol-induced liver injury. The liver-specific transgenic zebrafish larvae (lfabp: EGFP) at three days post-fertilization (3 dpf) were treated with different concentrations of PCP (100, 50 and 25 μg/mL) for 48 h, after soaked in a 350 mM ethanol for 32 h. Whole-mount oil red O, H&E staining and biochemical kits were used to detect fatty liver function and fat accumulation, western blot (WB) and immunofluorescence were used to determine proteins expression, and RT-qPCR was used to further verify the related gene expression. PCP restored zebrafish liver function. Additionally, PCP (as dose-dependent) blocked the expression of cytochrome P450 2E1 (CYP2E1), the production of intracellular reactive oxygen species (ROS) and alleviated liver fat accumulation and oxidative damage. PCP exerted its hepatoprotective function by downregulating the expression of kelch-like ECH-associated protein 1 (Keap1), up-regulating the expression of nucleus factor-E2-related factor 2 (Nrf2) (transferring to the nucleus), and attenuating systemic oxidative stress. Furthermore, PCP reduced the expression of sequestosome 1 (p62/SQSTM1, p62), Atg13, and Beclin 1, up-regulating autophagy signaling pathway. Taken together, the molecular evidence that PCP protected the ethanol-induced hepatic oxidative stress and autophagy impairment through activating AMPK/p62/Nrf2/mTOR signaling axis.

  • Teff Grain-Based Functional Food for Prevention of Osteoporosis: Sensory
           Evaluation and Molecular Docking Approach

    • Free pre-print version: Loading...

      Abstract: Abstract Osteoporosis is a highly prevalent skeletal disorder, which is characterized by compromised bone strength predisposing to an increased risk of fracture. The medical approaches presently followed for the prevention and treatment are associated with several side effects. Thus, it becomes important to design alternatives that are safer, economical, and easy to use. Plants provide us with a beneficial and effective option for such designs. They are rich in nutrients and phytochemicals that can be used to target signalling pathways to prevent the development of disease. For this purpose, we used Ethiopian grain, teff as a preventive strategy for osteoporosis as it has a favourable nutritional profile. In our study, we focussed on the preparation of functional multi-grain flour with Ethiopian grain, teff, and other ingredients that have a positive effect on bone health. A cookie was prepared from the multi mix flour and to analyze its shelf life and acceptance we performed a sensory evaluation where we observed no significant difference in the cookies’ characteristics during the period of study. We also performed Molecular Docking of eight flavonoid polyphenols selected from the nutritional profile of the ingredients to understand their binding affinity, interaction with the target, receptor activator of nuclear factor kappa-Β ligand (RANKL), and prophylactic or therapeutic effects in the prevention of osteoporosis. It was found that all 8 flavonoid polyphenols bound with RANKL, at least at one of the crucial binding sites and so can be used for the prevention of osteoporosis.

  • Chia (Salvia hispanica L.) Seed Germination: a Brief Review

    • Free pre-print version: Loading...

      Abstract: Abstract Chia (Salvia hispanica L.) is a seed native to northern Mexico and southern Guatemala that has started to be consumed in recent years in other regions of the world owing to its nutritional and functional properties. Germination of chia seeds seems to be able to further improve these properties, and it has been the subject of some studies. In general, germination has proven to be a simple and inexpensive process capable of improving the content of phenolic compounds and the antioxidant capacity of foods, as well as reducing antinutritional factors that interfere with nutrient absorption. A particular characteristic of chia seeds is that they produce mucilage when they are hydrated. For this reason, the germination conditions of the seed need to be adapted. The nutritional guidelines of some countries, such as Brazil, Germany and Sweden, recommend that the diet of the population should be more plant-based, thus encouraging the consumption of foods with a high content of bioactive compounds and nutrients, e.g., germinated seeds. This review briefly explored the germination conditions of chia seeds as well as the changes in phytonutrient content and antinutritional factors after their germination process. The main information available in the literature is that germination of chia seeds can increase the contents of protein, fiber, and total phenolic compounds. As a conclusion, germination of chia seeds is favorable for increasing their health benefits and nutritional value. However, chia germination parameters should be adjusted and microbiological risks should be properly evaluated.

  • Taurine Treatment Alleviates Intestinal Mucositis Induced by
           5-Fluorouracil in Mice

    • Free pre-print version: Loading...

      Abstract: Abstract Taurine (Tau), a β-amino acid, exists in red goji fruit (Lycium barbarum L.). It exerts many cellular physiological functions such as anti-inflammation and oxidation resistance. The chemotherapy drug 5-fluorouracil (5FU) can cause intestinal mucositis. However, current therapeutic approaches for mucositis have limited efficacy and are associated with various side effects. It is still unknown whether Tau can alleviate intestinal mucositis. This study aimed to investigate the protective effect of the Tau in a mucositis mouse model and elucidate the underlying molecular mechanisms. The intestinal mucositis symptoms were alleviated by the Tau administration as evidenced by decreased body weight loss, histopathological score, oxidative stress, and improved glutathione (GSH). The Tau supplementation strengthened intestinal epithelial tight junction and reduced serum lipopolysaccharide (LPS) levels in intestinal mucositis mice. Moreover, the 5FU-induced inflammatory responses were alleviated by Tau treatment via the nuclear factor erythroid 2-related factor 2/heme oxygenase-1 (Nrf2/HO-1) and nuclear factor kappa-B/inducible nitric oxide synthase (NF-κB/iNOS) signaling pathway. Tau administration modulated short chain fatty acids (SCFAs) in the colon of mice. The results indicated that the Tau might be a new dietary strategy for intestinal mucositis caused by 5FU.

  • Physicochemical and Colon Cancer Cell Inhibitory Properties of
           Theabrownins Prepared by Weak Alkali Oxidation of Tea Polyphenols

    • Free pre-print version: Loading...

      Abstract: Abstract Existing studies on the biological activity of theabrownins are not based on their free state but on the complexes of theabrownins, polysaccharides, proteins, and flavonoids. In this study, theabrownins (TBs-C) were prepared by weak alkali oxidation of tea polyphenols. The ultraviolet-visible scanning spectrum of TBs-C showed two characteristic absorption peaks at 203 and 270 nm. The zeta potential of the TBs-C aqueous solution was negative, and the values varied from − 6.26 to -19.55 mV with a solution pH of 3–9. Storage conditions of pH 5.0–7.0 and around 25 °C were beneficial for the physical and chemical stability of the TBS-C solution. Cells were treated with series concentrations and examined by MTT, HE staining, PI immunofluorescence staining, flow cytometry, and real-time PCR to investigate the antiproliferative effect of TBs-C on human colon cancer HT-29 cells. The results showed that TBs-C, particularly at 500 µg/mL, inhibited cell growth. TBs-C induced HT-29 cell apoptosis, as confirmed by morphological changes, nucleus propidium iodide staining, and distributions of the cell cycle. The apoptotic mechanism may be due to the intracellular redox imbalance induced by TBs-C.

  • Momordica charantia Extract Confers Protection Against Hypertension
           in Dahl Salt-Sensitive Rats

    • Free pre-print version: Loading...

      Abstract: Abstract Hypertension is one of the main factors of cardiovascular disease worldwide and is strongly related to the overall mortality. High salt intake is a major risk factors for hypertension. Identifying functional foods that can help prevent mechanistic abnormalities mediating salt-induced hypertension is an issue of considerable nutraceutical and scientific interest. Dietary Momordica charantia may be an alternative approach to avoid salt-induced hypertension. Dahl salt-sensitive (DSS) rats were used to determine whether Momordica charantia water extracts (ME) exerts anti-hypertensive effects in the present study. ME gavage could significantly prevented the increase of blood pressure, blood urea nitrogen, creatinine, and urine protein-to-creatinine ratio of DSS rats. Metabolomics analysis indicated that high-salt diet induced abnormal amino acid metabolism was related to nitric oxide (NO) deficiency, but ME gavage could upregulate the activities of nitric oxide synthase, aspartate aminotransferase, argininosuccinate lyase, argininosuccinate synthase and restore endogenous synthesis of arginine and NO. Meanwhile, renal function was improved after ME gavage. Citrulline, as one of the important component in ME, could attenuate salt-induced hypertension by increasing endogenous synthesis of arginine and NO. Antioxidants in ME, such as phenolic compound, may avoid high-salt induced oxidative stress in DSS rats, which may be another mechanism by which ME prevented blood pressure increase. Thus, the present study indicated that feeding Momordica charantia could avoid high-salt-induced hypertension in DSS rats.

  • Hypolipidemic Effects of Soy Protein and Isoflavones in the Prevention of
           Non-Alcoholic Fatty Liver Disease- A Review

    • Free pre-print version: Loading...

      Abstract: Abstract Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease and affects about 25% of the population globally. Obesity and diabetes are the main causes of the disease characterized by excessive accumulation of lipids in the liver. There is currently no direct pharmacological treatments for NAFLD. Dietary intervention and lifestyle modification are the key strategies in the prevention and treatment of the disease. Soy consumption is associated with many health benefits such as decreased incidence of coronary heart disease, type-2 diabetes, atherosclerosis and obesity. The hypolipidemic functions of soy components have been shown in both animal studies and human clinical trials. Dietary soy proteins and associated isoflavones suppressed the formation and accumulation of lipid droplets in the liver and improved NAFLD-associated metabolic syndrome. The molecular mechanism(s) underlying the effects of soy components are mainly through modulation of transcription factors, sterol regulatory element-binding protein-1 and peroxisome proliferator-activated receptor-γ2, and expressions of their target genes involved in lipogenesis and lipolysis as well as lipid droplet-promoting protein, fat-specific protein-27. Inclusion of appropriate amounts of soy protein and isoflavones in the diets might be a useful approach to decrease the prevalence of NAFLD and mitigate disease burden.

  • Antioxidant Activity and Profile of Phenolic Compounds in Selected Herbal
           Plants

    • Free pre-print version: Loading...

      Abstract: Abstract Herbs are characterized by a high content of biologically active substances that positively affect human health. Phenolic compounds are one of the main bioactive compounds in these plants with highly beneficial properties (e.g., anti-carcinogenic, cardioprotective, immune system support and antibacterial). Therefore, this study aimed to determine the composition of free and bound phenolic compounds and antioxidant activity in 10 different herbs (bogbean leaves, sage leaves, whole Indian hemp, whole heartsease, whole horsetail, whole blessed thistle, whole thyme, chamomile flower, corn silk and pine buds). Phenolic compounds were analyzed using the HPLC-TOF-MS/MS method, total phenolic (TP) and flavonoid (TF) contents were measured using spectrophotometric methods, while antioxidant activity was determined by ABTS and DPPH assays. The highest content of free TP was found in thyme, while sage was characterized by the highest range of these compounds released from ester and glycosidic derivatives by hydrolysis. In turn, the highest values of TF in non-hydrolyzed extracts were found in Indian hemp. The highest values of TF, including bound phenols were observed in extracts obtained from sage leaves. In the analyzed herbs thirty-three phenolic compounds were found, constituting 16 phenolic acids, 9 flavonoids and eight stilbenes. Moreover, the analyzed compounds appeared in the bound form than in the free form. The antioxidant activity of herb extracts differed significantly across varieties (P < 0.05). The research showed that each tested herb possesses its own fingerprint of phenolic compounds and antioxidant properties.

  • Effect of Yerba Mate (Ilex paraguariensis) on Lipid Levels: A Systematic
           Review and Meta-Analysis

    • Free pre-print version: Loading...

      Abstract: Abstract Several studies have evaluated the lipid-lowering properties of yerba mate, although the results were conflicting. The objective of this systematic review was to assess the effect of yerba mate consumption on lipid levels. A literature search was performed to detect observational and experimental studies that evaluated the association between yerba mate consumption and lipid levels. A quantitative analysis was performed with the subgroup of experimental studies. A meta-regression was performed considering the difference in baseline lipid values between the intervention and control groups as a covariate. Thirteen studies were considered eligible for this systematic review and seven studies (378 patients) were selected for quantitative analysis. In the qualitative analysis, the results were conflicting, both in the observational and in the experimental studies. In quantitative analysis, we found no differences in total cholesterol [mean difference 6.4 (CI 95% -2.2 to 15.0)], LDL-C [mean difference 5.5 (CI 95% − 1.5 to 12.6)], HDL-C [mean difference 0.4 (CI 95% -2.8 to 3.7)] and triglycerides [mean difference 5.7 (CI 95% 0.0 to 11.4)] levels when comparing the yerba mate and control groups. According to meta-regression, differences between baseline levels could influence the findings on total cholesterol and LDL-C but not on HDL-C or triglycerides. In conclusion, this research showed that yerba mate consumption was not associated with a significant change in lipid levels. Since the results are based on small inconclusive studies, more research is needed to confirm these findings.

  • Utilizing of the Common Dehydrating Techniques to obtain maximum benefit
           from the Protein and mineral Composition of rosemary leaves for Spice and
           Herbal Tea Production

    • Free pre-print version: Loading...

      Abstract: Abstract In the study, we examined in detail the effect of dehydrating using natural drying in the shade, convection drying, and microwave drying, which are the most widely used techniques, especially for tea and spices, both in practice and in theory, on the protein, and mineral composition of rosemary leaves. Also, we determined the color parameters, which are the reason for the selection because it creates the allure for spices. In microwave drying at 600 W, we obtained results close to fresh rosemary in all color parameters, especially brightness and greenness. Although natural drying, which does not have any energy and investment costs, is the second-best method in terms of color, 50 °C, which is the most common drying technique in the market, caused significant color losses affecting the commercial value of the product. We reached the closest protein and P, Ca, Mg, Fe, Zn, Mn, and contents to fresh products in dried ones at 600 W. In contrast, in K only, the highest measurement was at 200 W. Strikingly, we observed dramatic losses reducing the benefit obtained from the product regarding protein and almost all nutrients in both convective and natural drying techniques, the most common methods in practice.

  • Starch Digestion in Infants: An Update of Available In
           Vitro Methods—A Mini Review

    • Free pre-print version: Loading...

      Abstract: Abstract Complementary feeding starts at around six months of age because neither breast milk nor formula assure the proper nutrition of infants. Therefore, along with breast milk, solid foods are gradually introduced, particularly cereal-based foods, which will provide starch as a new source of energy and nutrients. As a result, the need of an adequate in vitro digestion method to study the influence of different aspects of weaning period is unquestionable. This critical review summarizes the in vitro digestion methods available for the analysis of starch hydrolysis under infant conditions considering different features, namely, starch digestion, infant digestive conditions and in vitro models suitable for the study of starch digestion (static, semi-dynamic and dynamic). Key factors such as enzyme concentrations, transit time, oral, gastric and intestinal conditions and differences with current adult models, have been addressed. The need for standardized infant digestion models adapted to the complementary feeding period was discussed. Existing literature data demonstrate that more effort has to be done to improve the research on this issue, in order to obtain comparable results that would address a better understanding of the digestibility of different food nutrients under infant conditions facilitating the development of appropriate formulations that may assure proper infant nutrition.

  • Spray-drying Microencapsulation of an Extract from Tilia tomentosa Moench
           Flowers: Physicochemical Characterization and in Vitro Intestinal Activity
           

    • Free pre-print version: Loading...

      Abstract: Abstract Silver linden (Tilia tomentosa Moench, TtM) flowers possess several health-promoting properties, especially at the neurological level, such as intestinal relaxation activity associated with specific flavonols, particularly quercetin and kaempferol derivatives. However, such molecules are susceptible to degradation upon different triggers like heat, light and extreme pH values. To overcome the scarce stability of TtM flowers bioactive molecules and make them suitable for developing functional food and supplements, we applied microencapsulation. Spray-drying microencapsulation of TtM flowers extract was performed using three starch-derived wall materials: maltodextrin 12 DE (MD12) and 19 DE (MD19), and OSA-modified starch (OSA-S). The stability of total phenols, flavanols, and antioxidant capacity was monitored for 70 days under accelerated stress conditions (40 °C/70% RH) by HPLC and spectrophotometric methods, and the intestinal contractile activity was tested in a murine model. In comparison to MD12 and MD19, OSA-S stood out for the higher encapsulation efficiency of quercetin and kaempferol glycosides (+ 36–47% compared to MD12 and + 18–24% compared to MD19) and stability thereof (half-life on average + 30% compared to MD12 and + 51% compared to MD19). The intestinal contractile activity of OAS-S powders resulted comparable to the original extract, indicating that flavonols were biologically active and accessible. Our results underly the potential advantages of OSA-S encapsulated formulation as a functional ingredient for the development of nutraceutical products.

           Phytochemical Composition by UHPLC–ESI–MS/MS

    • Free pre-print version: Loading...

      Abstract: Abstract Lepidium meyenii Walp (red maca) is a high Andean plant cultivated since the Incas and has innumerable therapeutic properties. The study aims to identify its phytochemical composition using UHPLC–ESI–MS/MS, and evaluate its effects on acrylamide-induced oxidative stress. The lyophilized aqueous extract of red maca (LAqE-RM) was orally administered in doses of 1 and 2 g/kg body weight for 4 weeks. Malondialdehyde (MDA) levels in erythrocytes, brain, and liver, as well as hepatic levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined. Administration of acrylamide for 2 and 4 weeks significantly increased (p < 0.001) MDA levels in erythrocytes, brain, and liver. However, LAqE-RM prevented (p < 0.001) an increase in MDA levels in all tissues studied. Likewise, the groups treated with LAqE-RM presented significantly (p < 0.001) lower levels of ALT and AST compared to the control. Treatment with LAqE-RM ameliorated the acrylamide-induced oxidative stress by reducing MDA levels in erythrocytes, brain, and liver and by lowering liver levels of ALT and AST in a dose-dependent manner. Twenty-five secondary metabolites were identified and characterized from LAqE-RM based on UHPLC mass spectrophotometry. These include carbolines, alkamides, fatty acids, and macamides, which are probably involved in their antioxidant protective role.

  • Allergenic Content of New Alimentary Pasta Made of Lentils Compared with
           Lentil Seeds and Analysis of the Impact of Boiling Processing

    • Free pre-print version: Loading...

      Abstract: Abstract There is growing interest in legumes such as lentil as healthy ingredients in gluten-free products. In that respect, foods based on lentils, like alimentary pasta, have been produced and successfully commercialized in recent years. Lentils are also known for inducing severe allergic reactions; however, it is currently unknown if novel alimentary pasta based on lentil retains the same allergenic potential as lentil seeds. In this study, the allergenic content of alimentary lentil pasta compared with lentil seeds was analyzed by immunoassays using sera from patients with allergic sensitization to lentil or with specific antibodies that recognize major lentil allergens. The effect of boiling processing was also analyzed. Results showed that alimentary lentil pasta has a significant allergenic content close to the general allergenic content observed for lentil seeds. Both alimentary lentil pasta and lentil seeds were similarly affected by boiling, with an important transfer of allergens from the food to the boiling water. This study shows that alimentary pasta made of lentils has a significant allergenic potential and highlights the necessity to analyze the allergenic content of new foods and novel ingredients introduced in traditional food products.

  • Heated Leaf Extract of Coriandrum sativum L. Protects Nigral Dopaminergic
           Degeneration in Rats

    • Free pre-print version: Loading...

      Abstract: Abstract Coriandrum sativum L. (coriander), which is an annual herb of the Apiaceae family, has been traditionally used as a remedy. Here we tested whether heated extract of coriander leaf protects nigral dopaminergic neurodegeneration after exposure to 6-hydroxydopamine (6-OHDA). After injection of 6-OHDA into the rat substantia nigra pars compacta (SNpc), dopaminergic degeneration, which was determined by tyrosine hydroxylase immunostaining, was rescued by co-injection of CaEDTA, an extracellular Zn2+ chelator, suggesting that extracellular Zn2+ influx is involved in neurodegeneration. Both intracellular Zn2+ dysregulation determined by ZnAF-2 fluorescence and dopaminergic degeneration in the SNpc induced by 6-OHDA were rescued by co-injection of 0.25% coriander extract, which also reduced reactive oxygen species (ROS) production in the SNpc determined by aminophenyl fluorescein fluorescence. The present study suggests that coriander leaf extract protects nigral dopaminergic neurodegeneration induced by intracellular Zn2+ dysregulation. It is likely that the nutraceutical property of coriander leaf extract contributes to the protection via reducing ROS production.

           of Matcha Tea on Overweight and Obese Individuals: A Pilot Observational
           Study

    • Free pre-print version: Loading...

      Abstract: Abstract Matcha tea has been used as an adjunct in weight loss programs. The weight loss effects of matcha tea were evaluated in a prospective non-randomized open-label comparative study of overweight and obese individuals who followed a specified low-calorie diet (LCD) plan. A total of 40 participants were enrolled and assigned to either matcha tea or control groups. The matcha tea group followed a LCD plan and received matcha tea once daily, whereas the control group followed only the LCD diet plan. The study lasted 12 weeks. The main outcome measures included anthropometric measurements, fasting blood glucose, hemoglobin A1c (HbA1c), lipid profile, obesity-related hormone peptides, pro-inflammatory and anti-inflammatory cytokines, and oxidative stress biomarkers. Thirty-four participants had completed the study. The matcha tea and control groups showed significant reductions in body weight, body mass index, waist circumference, water content, minerals, and fat mass at week 12. The post-treatment body composition and anthropometric measurements were not significantly different between the two groups. The matcha tea group showed a potential increase in HDL-C, a potential decrease in blood glucose, and a potential increase in HbA1c. Furthermore, the study indicated a potential decrease in insulin and leptin levels, a potential increase in the activity of superoxide dismutase, and a potential decreased activity of glutathione peroxidase. IL-10 was increased by matcha tea consumption. The data suggest that matcha tea may have some potential effect on weight loss, along with anti-inflammatory properties. The findings of this study will be used to design a multicenter randomized clinical trial to examine the potential weight loss benefits of matcha tea.

           Ingredients Before Consumption and Possible Links with Health Outcomes
           After Consumption- A Review

    • Free pre-print version: Loading...

      Abstract: Abstract Bread is a commonly consumed staple and could be a viable medium to deliver plant-based ingredients that demonstrate health effects. This review brings together published evidence on the bioactive properties of bread formulated with plant-based ingredients. Health effects associated with the consumption of bread formulated with plant-based functional ingredients was also reviewed. Bioactive properties demonstrated by the functional ingredients fruits and vegetables, legumes, nuts and tea incorporated into bread include increased phenolic and polyphenolic content, increased antioxidant activity, and extension of bread shelf-life by impairment of lipid and protein oxidation. Acute health effects reported included appetite suppression, reduced diastolic blood pressure, improvements in glycaemia, insulinaemia and satiety effect. These metabolic effects are mainly short lived and not enough for a health claim. Longer term studies or comparison of those who consume and those who do not are needed. The incorporation of plant-based functional ingredients in bread could enhance the health-promoting effects of bread.

           Targeting Energy Metabolism in Hepatic Cancer

    • Free pre-print version: Loading...

      Abstract: Abstract In the past few years, evidence has supported the role of plants as a valuable tool for the development of promising therapeutic support options for many diseases, including cancer. We recently discovered that the edible wild plant Crithmum maritimum L. effectively inhibits the growth of hepatocellular carcinoma (HCC) cells and we provide insights into the biological mechanisms involved. Here, we aimed to characterize the effect of ethyl acetate extract of Crithmum maritimum on the bioenergetic phenotype of HCC cells and if this is associated with the anti-tumour effect we previously described. Results show that Crithmum maritimum significantly increases cellular respiration and reduces lactic fermentation in HCC cells, and that this reduction of the fermentative glycolytic phenotype is linked to inhibition of HCC growth. These data provide new preclinical evidence supporting the role of Crithmum maritimum L. as a nutraceutical option to expand the therapeutic opportunities in the management of HCC.

      Abstract: Abstract Fruit and fruit juices are a valuable source of bioactive compounds, which can protect our organisms from oxidative stress. The phenolic compounds and other phytochemicals may affect the antimicrobial properties of juices. The aim of this study has been to evaluate antioxidant and antimicrobial properties of selected berry juices and vitamin C-rich fruit juices. The research material was composed of seven juices, including three from berries (elderberry chokeberry, cranberry), three from vitamin C-rich fruit (sea buckthorn, wild rose, Japanese quince) and one exotic juice from noni fruit. Antioxidant capacity, total polyphenol, total flavonoid and total anthocyanin content were determined. Furthermore, the antimicrobial activity and the minimal inhibitory concentration (MIC) as well as the minimal bactericidal concentration (MBC) were evaluated. The research showed that fruit juices from wild rose, chokeberry and Japanese quince had the highest antioxidant capacity. These juices were characterised by the rich content of polyphenols. Elderberry and chokeberry juices had the highest total anthocyanins. The juices differed in the content of bioactive compounds and specific bactericidal properties against Gram-positive or Gram-negative bacteria. Fruit juices from cranberry, Japanese quince and sea buckthorn had the highest antimicrobial activity. Wild rose, chokeberry and elderberry juices, despite their high antioxidant properties, showed antimicrobial activity only against Gram-positive strains, except Enterococcus faecalis and Clostridium perfringens. Significant differences in the content of bioactive compounds in fruit juices affect the antimicrobial properties juices.
