Öğe A Note on Battarrea phalloides in Turkey(2021) Akata, Ilgaz; Altuntaş, Deniz; ŞAHİN, Ergin; ALLI, HAKAN; Kabaktepe, SanliThe current study was conducted based on a Battarrea sample obtained from Muğla province (Turkey). The sample was identified based on both conventional methods and ITS rDNA region-based molecular phylogeny. By taking into account the high sequence similarity between the sample (ANK Akata & Altuntaş 690) and Battarrea phalloides the relevant specimen was considered to be B. Phalloides and the morphological data also strengthen this finding. In this study, photos of macro and microscopic structures, a short description, scanning electron microscope (SEM) images of spores and elaters, and the ITS rDNA region-based molecular phylogeny of the samples were given. Also, the distribution of B. phalloides specimens identified thus far from Turkey was revealed for the first time in this study.Öğe COMPARISON OF ANTIMICROBIAL, ANTIOXIDANT ACTIVITIES AND CHEMICAL CONTENTS OF ENDEMIC HYPERICUM MALATYANUM AND HYPERICUM PERFORATUM SPECIES GROWING IN MALATYA(Pakistan Botanical Soc, 2025) Ozbey, Elif; Asma, Dilek; Kabaktepe, SanliPlants are being used for various purposes since ancient times and have an important place in improving human health. Studies have shown that plant components contain any phytochemical compounds with strong antioxidant and antimicrobial activity. Plants and their essential oils have been studied in number of research fields in terms of their antimicrobial and antioxidant effects, especially since 1940 and important results have been obtained. Hypericum perforatum L, also known as St. John's wort, is one of these medicinally important plants, traditionally widely used and recognized as a valuable herbal medicine for more than 2000 years. In this study, the antimicrobial properties and antioxidant capacity of H. perforatum L. (St. John's wort) were determined and compared with Hypericum malatyanum Pe & scedil;men, a species endemic to Malatya. The antimicrobial activity of the extracts of these plants were tested and compared against the microorganisms consisting of selected bacteria and yeasts. It was found that they were more effective against bacteria. The best results in antioxidant activity tested by DPPH radical scavenging activity were recorded as 90. 80 % in Malatya St. John' s wort at a concentration of 1000 mu l. The chemical content of the samples of H. perforatum and H. malatyanum plant extracts were determined by GC/MS method and as a result, 14 of the 30 different chemical components identified in both plants showed differences.Öğe DETERMINATION OF THE EFFECTS OF BIOTIC STRESS CAUSED BY Puccinia Malvacearum IN Malva Sylvestris BY SOME BIOCHEMICAL AND PHYSIOLOGICAL PARAMETERS(Parlar Scientific Publications (P S P), 2021) Temel, Mehmet; Yigit, Emel; Kabaktepe, Sanli; Akbulut, Gulcin BekerIn this study, the effects of Puccinia malvacearum, an important rust fungus in the phylum Basidiomycota, on Malva sylvestris (mallow) were investigated. Changes in pigment content, dry weight, malondialdehyde (MDA), which is an important marker of lipid peroxidation, total phenolic content, peroxidase (POD) and ascorbate peroxidase (APX) enzymes were investigated in groups infected with rust fungi and those that were not. In the infected group, an increase in pigment content was observed in samples obtained in June and July. The increase in MDA content in infected groups was also considered an indicator that caused oxidative stress in M. sylvestris. In addition, a decrease in POD activity and an increase in phenolic content were observed in the infected group. APX activity was also increased in the infected groups. Additionally, changes in the dry weight content were observed in the infected groups. Our findings showed that M. sylvestris gave important physiological and biochemical responses to oxidative stress caused by P. malvacearum. It is thought that the data obtained in this study will contribute to the elucidation of resistance mechanisms in plants exposed to fungal infection.Öğe EVALUATION OF ANTIOXIDANT POTENTIAL, ANTICHOLINESTERASE ACTIVITY AND ELEMENT CONTENT OF CHLOROPHYLLUM RHACODES SPECIES(Medical Univ Warsaw, 2026) Akata, Ilgaz; Baba, Hayri; Kabaktepe, Sanli; Sevindik, MustafaIn this study, antioxidant potential, anticholinesterase activity, and elemental contents of Chlorophyllum rhacodes were evaluated. In order to determine the antioxidant capacity, total antioxidant status (TAS), total oxidant status (TOS), oxidative stress index (OSI), DPPH radical scavenging activity, and FRAP ferric reducing power analyses were applied. According to the obtained results, the TAS value was determined as 3.125 +/- 0.060 mmol/L, the TOS value as 6.821 +/- 0.062 & micro;mol/L, the OSI value as 0.218 +/- 0.003, DPPH activity as 55.430 +/- 1.438 mg TE/g, and the FRAP value as 72.540 +/- 1.461 mg TE/g. These data revealed that C. rhacodes showed a significant level of antioxidant activity. In the evaluation of anticholinesterase activity, inhibitory effects against AChE and BChE enzymes were determined, and IC50 values were found as 94.330 +/- 1.536 & micro;g/mL and 128.397 +/- 1.556 & micro;g/mL, respectively. These results show that C. rhacodes exhibits limited inhibitory effect on these enzymes but may have a certain level of anticholinesterase potential. According to the results of elemental analysis, Cd (14.78 +/- 1.53), Cr (33.17 +/- 1.42), Mn (7.35 +/- 0.52), Cu (155.77 +/- 2.34), Fe (469.30 +/- 15.75), Pb (6.98 +/- 0.54), Ni (3.66 +/- 0.31) and Zn (76.18 +/- 2.25) mg/kg levels were detected in mushroom samples. In particular, it was observed that Cd and Cu levels were above the upper limits specified in the literature. This finding shows that C. rhacodes tends to accumulate some heavy metals and may be highly sensitive to environmental pollution. In conclusion, C. rhacodes exhibits a biologically remarkable profile with certain antioxidant and anticholinesterase activities and can also be considered as a potential indicator species in the biological monitoring of environmental metal exposure.Öğe First reports of Milesina and Triphragmium from Turkey(Mycotaxon Ltd, 2022) Kabaktepe, Sanli; Akata, Ilgazspecies Milesina scolopendrii on Asplenium scolopendrium and Triphragmium filipendulae on Filipendula vulgaris are reported from Melsin, Turkey.

The study evaluated the biological activity of Phellinus hartigii (Allesch. & Schnabl) Pat. and optimized extraction conditions to the maximize its bioactive potential.MethodsExtraction was performed using a Soxhlet apparatus under varying conditions: temperatures (30, 50, and 70 degrees C), durations (1, 5.5, and 10 h), and ethanol/water ratios (0%, 50%, and 100%). Total antioxidant status (TAS) was analyzed across 17 experiments, and the optimal conditions were identified using response surface methodology (RSM). Extracts from optimal conditions were further analyzed for antioxidant capacity (Rel assay kits, DPPH, FRAP), anticholinesterase activity (acetyl- and butyrylcholinesterase inhibition), antiproliferative activity (A549 lung cancer cell line), total phenolic content (Folin-Ciocalteu method), and phenolic compound profile (LC-MS/MS).ResultsOptimal extraction conditions were determined to be 48.22 & ring;C, 9.04 h, and an ethanol/water ratio of 52.22%. The extract exhibited significant antiproliferative effects against the A549 lung cancer cells, with activity increasing in a concentration-dependent manner. The inhibition values (IC50) of acetylcholinesterase and butyrylcholinesterase were 21.29 +/- 0.41 and 35.51 +/- 0.53 mu g/mL, respectively. The TPC (total phenolic content) value of the optimized extract was determined as 88.21 +/- 1.50 mg/g, FRAP value as 137.81 +/- 1.72 mg/g, DPPH value as 106.07 +/- 2.44 mg/g, TOS (total oxidant status) value as 9.27 +/- 0.06 mu mol/L, TAS value as 4.98 +/- 0.03 mmol/L and OSI (oxidative stress index) value as 0.19 +/- 0.002. LC-MS/MS analysis identified nine phenolic compounds, with gallic acid and catechin hydrate as the most abundant.ConclusionsThe extract of P. hartigii obtained under optimal conditions demonstrated substantial antioxidant, anticholinesterase, and antiproliferative activities, highlighting its therapeutic potential.Öğe Truffle Checklist of Turkey II with A New Record(2022) Akata, Ilgaz; ŞEN, İSMAİL; SEVİNDİK, Mustafa; Kabaktepe, SanliThe current study presents a Turkish Truffle Checklist based on literature and a newly discovered species.
