  • The occurrence of fungi on the commercial dietary supplements based on the
           milk thistle ( (L.) Gaertn.) available on Polish market

    • Abstract: SummaryIntroduction: Milk thistle (Silybum marianum (L.) Gaertn.) is an important medicinal plant, its achenes contain a silymarin, which has a regenerating and stabilizing effect on liver cells. The milk thistle based dietary supplements are among the best-selling plant pharmaceuticals in the US and the UE.Objective: The goal of the experiment was to determine which – if any – fungi contaminated either the whole or ground milk thistle achenes, available on the Polish market.Methods: The mycological analyses were performed on 200 achenes, using deep-freeze blotter method. Ground material was assessed using agar test method. For each sample, 10 Petri dishes were used. The material was applied in five places per one Petri dish, with a micro scoop laboratory spatula. Then, Petri dishes with achenes and ground material were incubated at 20°C under alternating cycles of 12 h NUV light and 12 h darkness. The identification of fungi was performed using stereo microscope and compound microscope, if necessary.Results: The milk thistle achenes were infested with following fungi: Alternaria alternata, Alternaria sp., Aspergillus flavus, Aspergillus spp., Bipolaris sp., Cladosporium spp., Epicoccum nigrum, Fusarium spp., Melanospora simplex, Mucor spp., Penicillium spp., Phoma sp., Rhizopus stolonifer, Sarocladium strictum, Stemphylium botryosum, Trichothecium roseum, Ulocladium consortiale and Verticillium sp. Among them A. alternata predominated. Whereas, milled milk thistle achenes were occupied by Aspergillus flavus, A. niger, Aspergillus spp., Fusarium sp., Mortierella spp., Mucor spp., Penicillium spp. and R. stolonifer.Conclusion: Considering the significant fungal contamination of milk thistle achenes-based dietary supplements, it seems reasonable to introduce a system of achene control due to possible microbiological contamination.

  • Anti-methicillin resistant and growth inhibitory studies of extract and
           fractions of leaves of (Lam.) Kurz ()

    • Abstract: SummaryIntroduction: Bryophyllum pinnatum is a plant with diverse ethnomedicinal claims yet to be verified scientifically.Objective: This work was aimed at evaluating the extract and vacuum liquid chromatographic (VLC) fractions of B. pinnatum on methicillin-resistant Staphylococcus aureus (MRSA) and anti-proliferating seed radicle cells of Sorghum bicolor.Methods: The extract and VLC fractions of B. pinatum were screened phytochemically and subsequently tested against MRSA at concentrations of 3.125–100 mg/ml, while the antiproliferative assay at 1–30 and 1–10 mg/ml.Results: The extract recorded zone of inhibition of 7.05 mm was only at 100 mg/ml against L20 MRSA strains. While VLC bulked fractions A(1), C (5–7), D (8–9) and E (10) had no zones of inhibition against the strains, fraction B had zones of inhibitions at all concentrations with the highest ones of 9.7 and 8.5 mm at 125 and 62.5 mg/ml, respectively, against MRSA sample (L20). The MIC of the active fraction B was observed at 3.9, 7.8 and 15.6 mg/ml for all samples used. At 96 h of seed incubation, 56 mm radicle length was recorded by the control seeds was reduced to 1.5 mm (97%) and 0.4 mm (99%) when treated with 20 and 30 mg/ml of the extract. The VLC sub-fraction B at 10 mg/ml showed more inhibitory effects on the germinating radicles as it recorded 100% reduction when compared to the control at 96 h against 80 and 70% recorded by fractions ‘A’ and ‘C’, respectively.Conclusion: The results obtained showed an evidence of susceptibility of methicillin-resistant Staphylococcus aureus and growth inhibitory potentials of B. pinnatum, particularly the active VLC fraction “B”. Thus, further studies are required to support these findings.

           diabetic cataract: A review

    • Abstract: SummaryIntroduction: Aldose reductase (AR) is an enzyme that catalyzes the reduction of glucose to sorbitol responsible for the development of diabetic complications like cataracts. Medicinal plants contain several phytocompounds that can inhibit this enzyme.Objective: The purpose of this review is to cite medicinal plants that have been tested for their ability to inhibit aldose reductase and consequently prevent cataracts and classify the major isolated compounds that have this activity.Methods: We reviewed 154 articles published between 1954 and 2020 in English via three databases: ScienceDirect, Web of Science, and PubMed. We have classified the plants that showed a significant anti-cataract effect, in the form of a list including the scientific and family names of each plant. Also, we have cited the IC50 values and the active constituents of each plant that showed inhibitory activity towards AR.Results: We have described 38 herbs belonging to 29 families. Besides, 47 isolated compounds obtained from the cited herbs have shown an AR inhibitory effect: luteolin, luteolin-7-O-β-D-glucopyranoside, apigenin, 3,5-di-O-caffeoyl-epi-quinic acid, delphinidin 3-O-β-galactopyranoside-3’-O-β-glucopyranoside, 3,5-di-O-caffeoylquinic acid methyl ester, andrographolide, 1,2,3,6-tetra-O-galloyl-β-D-glucose, 1,2,4,6-tetra-O-galloyl-β-D-glucose, 7-(3-hydroxypropyl)-3-methyl-8-β-O-D-glucoside-2H-chromen-2-one, E-4-(60-hydroxyhex-30-en-1-yl)phenyl propionate, delphinidin 3-O-β-galactopyranoside-3’,5’-di-O-β-glucopyranoside, 1,2,3-tri-O-galloyl-β-D-glucose, 1,2,3,4,6-penta-O-galloyl-β-D-glucose, 1,2,6-tri-O-galloyl-β-D-glucose, 2-(4-hydroxy-3-methoxyphenyl)ethanol, (4-hydroxy-3-methoxyphenyl)methanol, trans-anethole, gallic acid 4-O-β-D-(6’-O-galloyl)-glucoside, β-glucogallin, puerariafuran, quercetin, gallic acid 4-O-β-D-glucoside, 2,5-dihydroxybenzoic acid, 4-(4-hydroxy-3-methoxyphenyl)-2-butanone, protocatechuic acid, trans-cinnamic acid, gallic acid, p-coumaric acid and syringic acid.Conclusion: natural therapy becomes an interesting alternative in the treatment and prevention of cataract by using medicinal plants rich in active compounds considered as AR inhibitors.

  • Kinetic study on peroxidase inactivation and anthocyanin degradation of
           black cherry tomatoes ( cv. OG) during blanching

    • Abstract: SummaryIntroductionBlanching is a necessary treatment stage in processing of tomato products to inactivate enzymes. However, it may cause the degradation of nutrients.ObjectiveIn this study, the kinetics of thermal peroxidase inactivation and anthocyanin degradation in black cherry tomatoes (cv. OG) were determined to predict the quality changes during the blanching.MethodsTomatoes were blanched at five levels of temperature (75–95oC) for five time periods (30–150 s).ResultsIt was found that as the blanching temperature increased and the blanching time is prolonged, more peroxidase was inactivated and the greater number of anthocyanins was lost. The thermal peroxidase inactivation and anthocyanin degradation showed an apparent first-order reaction with the activation energy of 129.96 kJ/mol and 65.99 kJ/mol, respectively. Peroxidase and anthocyanin in black cherry tomatoes were found to be heat-sensitive.ConclusionThese kinetic parameters were necessary to select and design appropriate blanching conditions for black cherry tomatoes on larger scale processing.

  • HPLC-DAD phenolics screening and investigation of haemostatic,
           antidiabetic, antioxidant and photoprotective properties of Boiss. & Reut.

    • Abstract: SummaryIntroductionTraditional medicine has an important place in human history and this since antiquity. Indeed, during Egyptian and Chinese civilization era, many detailed manuscripts, describing the therapeutic effect of plants, were found which suggest that folk medicine is the basis of the actual medicine.ObjectiveTo investigate the phytochemical and pharmacological properties of the n-butanol (n-BuOH) and ethyl acetate (EA) extracts of the aerial part of Centaurea tougourensis.MethodsThe phytochemical evaluation was done based on HPLC-DAD approach. The antioxidant activity was determined by DPPH and cupric ion reducing antioxidant capacity (CUPRAC), while the hemostatic effect was performed using plasma recalcification time (PRT) method. The antidiabetic capacity was investigated by alpha-amylase inhibition assay and the photoprotective test was evaluated by the measurement of sun protection factor (SPF).Results13 phenolic compounds were identified in both extracts of C. tougourensis. These extracts showed antioxidant, haemostatic, antidiabetic and photoprotective properties with a dose-dependent manner. Amounts of n-BuOH activities were found higher, with a respective IC50 value of 0.72±0.07 μg/ml in DPPH assay, an A0.50 value lower than 3.125 μg/ml in CUPRAC assay besides a shortening rate percentage of coagulation (86.71%) in haemostatic assay, a moderate inhibition effect on alpha amylase activity with an IC50 value of (711.5±0.03 μg/ml) and a maximum sun protection factor of (56.035). These results were mostly found highly significant (p<0.001) when compared to respective standards.ConclusionThis study demonstrated some pharmacological effects of C. tougourensis which suggests that our plant could be a good candidate to treat some illnesses related to oxidative stress, bleeding or skin cancer.

  • Phytochemical screening and galactagogic attributes of (Forssk.) Chiov.
           leaf extract in lactating mice ()

    • Abstract: SummaryIntroductionPergularia daemia (Forssk.) Chiov. [PD] is used as a galactagogue by various tribes in Purulia district, India, lacks a scientific basis.ObjectivesThe purpose of the study was to determine whether administration of aqueous leaf extract of P. daemia can increase milk production in lactating mice and encourages development in suckling pups.Methods30 lactating mice (n=6 per group) with a minimum of 5 pups each were treated with the aqueous PD extract at 50, 100, 150 and 200 mg/kg body weight while the control group was administered with only distilled water. The mice were daily fed with aqueous leaf extract via gavage, which started at day 3 and continued to day 15 post-partum and milk secretion was assessed by the weight-suckle-weight method. The qualitative estimation, UV-vis analysis and GC-MS study of the leaf extract was also done for the presence of phytoconstituents.ResultsAdministration of aqueous leaf extract led to a considerable increase in milk production (28.1%) and the pups gained weight substantially (p<0.05) when compared to control. Milk production was enhanced in mice treated with 150 mg/kg b.wt. of leaf extract compared to other doses (p<0.05). The GC-MS analysis of the aqueous leaf extract of P. daemia revealed 20 major peaks, some with small retention time and also revealing presence of several phyto-estrogenic compounds.ConclusionThe present study effectively demonstrated that aqueous leaf extract of PD enhanced milk production in mice and might be used as an alternative strategy for increasing milk production and can be extrapolated to farm animals and human beings.

  • Cytotoxic roles of apigenin and kaempferol on staurosporine-treated
           mesenchymal stem cells in an culture

    • Abstract: SummaryIntroductionFlavonoids are widely distributed in the wild. They constitute a large group of compounds that have a beneficial effect on the human body. Apigenin and kaempferol, which belong to the flavone subgroup, have, inter alia, an antitumor effect. The influence of these compounds on the survival of stem cells in a toxic environment has not yet been studied.ObjectiveThe aim of the study was to evaluate the effect of selected concentrations of apigenin and kaempferol on the survival of mesenchymal stem cells (MSC) in the presence of a cell-death inducer – staurosporine.MethodsMesenchymal stem cells that were obtained from the Wharton’s jelly of umbilical cords were used for the research. In the first stage, the MSC were treated with apigenin at concentrations of 1.2, 12.5, 25, 50 and 100 µM/ml and kaempferol at concentrations of 1.2, 12.5, 25, 50 and 100 µM/ml. In the next stage, the effect of increased concentrations of 0.1, 0.5 and 1 µM/ml of staurosporine on MSC was examined. The key stage of the experiment was investigating the interaction between the selected concentrations of apigenin (12.5 and 50 µM/ml) and kaempferol (12.5 and µM/ml) on MSC in the presence of staurosporine at a concentration of 1 µM/ml, which had the highest toxicity.ResultsBoth apigenin and kaempferol significantly increased the cytotoxic features of staurosporine on the MSC culture.

  • Probiotics in prevention and treatment of cardiovascular diseases

    • Abstract: SummaryIncreasing knowledge of the gut microbiota and its interference in human homeostasis in recent years has contributed to a better understanding of number of different interactions occurring in the gastrointestinal tract. Disruption of the microbiota is detrimental to health and contributes to the development of numerous diseases and may also be an accelerator of pathophysiological processes such as atherosclerosis. Cardiovascular diseases are the most common cause of death worldwide, so the development of new methods to support the treatment and prevention of these diseases becoms one of the priorities of modern medicine. Probiotics may constitute an important element of support in the treatment and prevention of CVD (cardiovascular diseases). A number of papers support such a statement, however, larger clinical trials are needed. Through a number of mechanisms including mitigating inflammation, sealing the intestinal epithelium, and affecting metabolism, probiotics may have a beneficial effect on general health and slow down the pathogenesis of many diseases, including those affecting the cardiovascular system. This article contains a review of current discoveries on the role of probiotics in the prevention and support of CVD treatment.

    • Abstract: SummaryIntroduction: The molecular basis of in vivo metabolism of selected representatives of phenylethanoids in the presence of ethanol has not been fully elucidated.Objective: The aim was to estimate a salidroside (Sal) metabolism in the liver tissue in rats with induced alcohol tolerance by assessing changes in the transcription of genes encoding cytochromes: CYP1A2, 2D2, 3A1, 2C23.Methods: cDNA was synthesized from total RNA isolated from rat liver samples. mRNA level changes were evaluated using real-time PCR (qRT-PCR) technique.Results: Ethanol caused a significant induction of the CYP1A2 and CYP2C23 genes transcription, and a decrease in the CYP3A1 mRNA level, predominantly without statistical significance. A statistically significant increase of the CYP1A2 mRNA level was observed in the group receiving only Sal (4.5 mg/kg b.w.; p.o.) (p<0.01).Conclusions: There was no unequivocal effect of salidroside on the transcription of investigated cytochrome genes in the liver of rats with induced alcohol tolerance.

  • Cytoprotective roles of epigallocatechin gallate and resveratrol on
           staurosporine-treated mesenchymal stem cells in culture

    • Abstract: SummaryIntroduction: There are many scientific reports on the beneficial effects of epigallocatechin gallate and resveratrol on the human body, e.g. antioxidant properties, a protective effect on the circulatory system and reduction of inflammation.Objective: The aim of the study was to evaluate the effect of these substances on the survival of mesenchymal stem cells (MSC) in the presence of the pro-apoptotic factor staurosporine.Methods: Cell viability WST-1 colorimetric assay.Results: It was confirmed that both 25 µM/ml and 50 µM/ml of epigallocatechin and 50 µM/ml of resveratrol statistically significantly increased the MSC survival rate.Conclusion: An excess supply of epigallocatechin gallate (50 µM/ml and higher) has a cytotoxic effect on MSC, which may have a negative impact on the body’s auto-regenerative capacity. Under toxic and stressful conditions, resveratrol and epigallocatechin gallate perform cytoprotective functions, thereby reducing the negative impact of toxic environmental conditions on the mesenchymal stem cells.

  • Pilot study of dietary supplement consumption by kindergarten and
           elementary school children

    • Abstract: SummaryIntroduction: The use of dietary supplements has been increasing globally, especially among children. A lot of parents are influenced by advertising. In addition, in Poland a trend to self-medication has been observed. Parents often do not distinguish dietary supplements, medicinal products and non-prescription drugs. These are the most common reasons for the increase in sales of dietary supplements in Poland. Until a few years ago, many products containing vitamins and minerals intended for children were sold as medicines. Today, a product with the same formulation is sold as a dietary supplement. However, a few studies have been conducted to assess the use of dietary supplements among Polish children.Objective: The aim of the study was to analyse the use of dietary supplements provided by parents and the study of the awareness of the risks associated with supplements intake among preschool and elementary school students.Methods: The study was conducted by questionnaire method among 316 parents/legal guardians of children attending elementary schools and preschools in three provinces.Results: The questionnaire was completed by 88.3% mothers and 11.7% fathers. The age of the respondents was as follows: 64.5% aged 31–40, 18.3% aged 41–45, 9.5% aged 26–30, 7.2% above 46 years and only 0.3% younger than 25. About 80% of parents administered their children with dietary supplements in specific situations. Vitamin and mineral supplements were predominant. A statistical analysis showed the effect of the education level as well as having many children on the administration of dietary supplements.Conclusion: The questionnaire shows that the vast majority of parents/legal guardians administer their children with dietary supplements. There is a need to educate parents/legal guardians about the use of supplements and the risks involved.

  • Phytochemical characterization of leaves

    • Abstract: SummaryIntroduction: Moringa oleifera (moringa) is a fast-growing tree from north India and Himalayan foothills considered to be one of the most nutritious species. Especially it’s leaves contain proteins in a high concentration, all essential amino acids, nutrients like calcium, iron, potassium and cooper, vitamin A, E and group B, and also antioxidants and polyphenols. Many studies have demonstrated the medicinal properties of moringa leaves consumption thanks to its antioxidant, anti-inflammatory, prevention of diabetes or antitumor and anticancer properties. The amount and number of essential nutrients and phytochemical constituents may vary depending on the plant tissue and age and especially on the climatic and edaphological conditions.Methods: We pointed to demonstrate moringa plants grown on proper conditions display a better production of its desired compounds. In this work, the mineral, amino acids, antioxidant activity and various bioactive compounds were analysed in moringa leaves extract from plants grown on Tenerife Island under organic production and similar climatic and edaphological conditions as the place of origin.Results: Our results revealed a high concentration of several nutrients as calcium, potassium and iron, as comparison to other moringa plants; β-carotene (pro-vitamin A), ascorbate (vitamin C) and glutathione, whose function is mainly antioxidant; chlorogenic acid with anticancer function; quercetin with antioxidant, anticancer and antidiabetic functions, among others; glucomoringin-isothiocyanate with anti-micro-biological and neuroprotective function.Conclusion: The results obtained in this study placed on Tenerife Island as one of the best suitable places for moringa good quality production and highlight the potential use of moringa novel food for humans and as a biostimulant for plants.

  • Microwave-assisted extraction of phenolic compounds from coffee ( L.
           Linden) bee pollen

    • Abstract: SummaryIntroduction: Coffee bee pollen contains some precious bioactive compounds, especially phenolic compounds. This material is easily found in many regions in Vietnam and is quite useful for human health.Objective: The main aim of this study was to determine the best extraction conditions for the total polyphenol content (TPC) and antioxidant capacity (AC) of coffee (Coffea robusta L. Linden) bee pollen with microwave-assisted extraction (MAE).Methods: TPC and AC of extract of coffee (C. robusta) bee pollen were determined using Folin-Ciocalteu (FC) and 2,2-diphenyl-1-picrylhydrazyl (DPPH) assay, respectively. In addition, micromorphology of sample was observed using scanning electron micrographs (SEM).Results: The findings showed that all factors strongly affected the efficiency of the extraction process. The best extraction conditions obtained were ethanol concentration of 60% (v/v), solid to solvent ratio of 1/30 (w/v), extraction time of 7 min, and a microwave power of 314 W.Conclusion: The highest TPC and AC obtained were 13.73 mg GAE/g DW and 10.08 µmol TE/g DW with aqueous ethanol as the solvent at the optimal extraction condition. In addition, the microstructures of the material changed insignificantly under microwave irradiation.
