Antioxidant, oxidant potentials and element content of edible wild mushroom Helvella leucopus

266-271This study aims to determine the total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), DPPH free radical scavenging activity and element levels of the mushroom Helvella leucopus Pers. Ethanol, methanol and dichloromethane extracts of the mushroom samples were obtained using a Soxhlet device. TAS, TOS and OSI values were determined using Rel Assay kits. Cr, Cu, Mn, Fe, Ni, Cd, Pb, and Zn contents were determined using an atomic absorption spectrophotometer. Consequently, this study has demonstrated that H. leucopus has antioxidant potential. As a result of the studies, TAS value of the mushroom was found as 2.181±0.069 mmol/L, TOS value was 14.389±0.170 μmol/L and OSI value was 0.661±0.022. DPPH free radical activity was determined as EtOH extract 49.80±0.71, MeOH extract 44.98±2.18 and DCM extract 23.68±1.37 in 1 mg/mL extract concentration of mushroom. In addition, it was found that the mushroom contains high levels of Pb and Mn. In conclusion, it was found that H. leucopus could be used as a natural agent in pharmacological designs due to its antioxidant activity

Antimicrobial screening of Mnium stellare

Many plants contain active substances that are known to be effective in both enhancing the wound healing process and lowering the incidence of wound infections. Previous studies have shown that bryophytes produce a variety of secondary metabolites that present pharmaceutical activities including antimicrobial activity against various pathogenic bacteria and fungi. The aim of this study was to investigate the antimicrobial activity of Mnium stellare against 17 bacterial and 1 fungal strains. Our present study has shown that the ethanol extract of M. stellare has antimicrobial activity against several Gram positive and Gram negative microorganism tested, but its antimicrobial activity is notable especially against B. subtilis, S. typhimirium, S. aureus, S. carnosus, and S. epidermidis. These results are the very first report of the antimicrobial activity of M. stellare

Background: Fungi have a potential of using both as nutritive and medicinal food stuff. Because of containing several therapeutic agents, they are reported to be used for hundreds of years to treat several diseases caused by bacteria, fungi, viruses and parasites. The aim of this study is to determine the in vitro antimicrobial activity of Xylaria hypoxylon, which were collected from Yomra, Trabzon, Turkey. Materials and Methods: X. hypoxylon samples were air dried and extracted by using ethanol. Antimicrobial activity of X. hypoxylon ethanol extracts were investigated against 21 bacterial and 2 fungal strains, namely, Bacillus subtilis DSMZ 1971, Bacillus subtilis ATCC 6633, Candida albicans ATCC 10231, Candida albicans DSMZ 1386, Enterobacter aerogenes ATCC 13048, Enterococcus durans, Enterococcus faecalis ATCC 29212, Enterococcus faecium, Escherichia coli ATCC 25922, Escherichia coli CFAI, Klebsiella pneumoniae, Listeria innocula, Listeria monocytogenes ATCC 7644, Pseudomonas aeruginosa DSMZ 50071, Pseudomonas fluorescence P1, Salmonella enteritidis ATCC 13075, Salmonella infantis, Salmonella kentucky, Salmonella typhimurium SL 1344, Staphylococcus aureus ATCC 25923, Staphylococcus carnosus MC1.B, Staphylococcus epidermidis DSMZ 20044 and Streptococcus agalactiae DSMZ 6784 by using the disk diffusion method. Results: It is observed that ethanol extracts of X. hypoxylon has antimicrobial activity against several Gram positive and Gram negative microorganisms tested. As a result of the study, an antimicrobial activity of X. hypoxylon found against most of strains used in the study. Conclusion: The results of our study clearly puts forward that X. hypoxylon could have a possible medicinal use

Distribution of Erysiphe platani (Erysiphales) in Ukraine

Information is provided on Erysiphe platani, a newly invasive fungus in Ukraine. The anamorph of this North American powdery mildew was first recorded in Ukraine in 1986 on Platanus orientalis in the Nikita Botanical Garden (Crimea). Later, it was found in other localities of the Crimean peninsula, and in Odessa and Odessa region on three species of plane, namely P. × hispanica, P. occidentalis and P. orientalis. Spread of the fungus was epiphytotic. This mildew significantly reduces the ornamental value of plane trees, which are often planted in public open spaces within urban areas of southern Ukraine. Recently, E. platani has formed the teleomorph in this region. Morphologically, the Ukrainian material is slightly different from the species description, viz. appendages are longer (up to 3 times the chasmothecial diam.), often with less compact apices

IN VITRO ANTIMICROBIAL SCREENING OF AQUILARIA AGALLOCHA ROOTS

Background: It was previously shown that some parts of Aquilaria agallocha, which is commonly known as oud or oodh, such as roots have been used as a traditional medical herbal in different countries. In Turkey A. agallocha is one of the ingredients while preparing famous Mesir paste, which was invented as a medicinal paste and used from the Ottoman period to now at least for 500 years. The identification the in vitro antimicrobial activity of ethanol extract of A. agallocha roots is main purpose of this analysis. Materials and Methods: By using 17 bacteria and 1 fungi, which include Bacillus, Candida, Enterobacter, Enterococcus, Escherichia, Klebsiella, Listeria, Pseudomonas, Salmonella and Staphylococcus genera, the activity of A. agallocha root extracts were analysed by the help of the disk diffusion method, that is one of the methods commonly used to determine antimicrobial activities. Results: As a result of the study it was observed that ethanol extracts of A. agallocha roots have a clear antimicrobial activity against nearly all microorganism used in the study, but only two bacteria namely E. coli ATCC 25922 and S. typhimurium SL 1344. Conclusion: According to the disk diffusion test results it may be possible to propose that A. agallocha roots should have a medicinal uses especially against E. faecium, L. monocytogenes ATCC 7644, B. subtilis DSMZ 1971, C. albicans DSMZ 1386, S. epidermidis DSMZ 20044 and S. aureus ATCC 25923

Oxidant/antioxidant potentials and heavy metal levels of Pisolithus arhizus and its effects on cardiovascular diseases

600-604Pisolithus arhizus (Scop) Rauschert is a cosmopolitan mushroom in warm temperate regions of the world and forms ectomycorrhizas associations with a wide range of tree species (both angiosperms and gymnosperms). P. arhizus samples were collected from a pine forest in Antalya province (Turkey). Powdered mushroom samples were extracted with ethanol (EtOH) using a Soxhlet apparatus at 50 °C, then concentrated under pressure at 40 °C in a rotary evaporator, and stored at 4 °C in airtight containers. Rel Assay Kits were used to determine the total antioxidant status (TAS), total oxidant status (TOS), and oxidative stress index (OSI) of mushroom extracts. The elemental contents of the mushrooms were then determined using the atomic absorption spectrophotometer. It was determined that the heavy metal content in P. arhizus were found to be generally at optimal levels and the TOS value of mushroom was exceptional. Heavy metals are toxic, they may have chronic degenerative changes on organs. Vascular effects of heavy metals may contribute to a variety of pathologic conditions. Heavy metals resulting in pathophysiological changes causes atherogenic events like increased oxidative stress, inflammatory response, and coagulation activity. It has been determined that P. arhizus may be an important source of antioxidants
