    Biological activity and fatty acid composition of Caesar's mushroom
    (TAYLOR & FRANCIS LTD, 2013) Doğan, Hasan Hüseyin; Akbaş, Gülsün
    Context: Due to its pleasant aroma and flavor, Amanita caesarea (Scop.) Pers. (Amanitaceae) has been a famous macrofungus since ancient times. This species is also well known in Turkey where people consume it extensively. Objective: Evaluation of the medicinal importance of A. caesarea for human health. Materials and methods: Antioxidant capacity of A. caesarea was studied using the methods of a scavenging effect on 2,2-diphenyl-1-picrylhydrazyl radicals, beta-carotene-linoleic acid assay, reducing power and estimation of phenolics. Chloroform, acetone and methanol extracts of A. caesarea were tested for their antimicrobial activity against four Gram-positive bacteria, five Gram-negative bacteria and one yeast by applying a micro dilution method. The fatty acids were estimated via the method of gas chromatography analysis. Results: The scavenging effect of A. caesarea on DPPH radicals was measured as 40.91% at 0.5 mg/mL concentration, and its reducing power was 0.451 mg/mL at 1.2 mg/mL concentration. The phenolics found were catechin (32.5 mg/g), ferulic acid (7 mg/g), p-coumaric acid (6 mg/g) and cinnamic acid (6.2 mg/g). The highest minimum inhibitory concentration observed against the test microorganisms were with the acetone extract (4.8 mg/mL concentration) against Candida albicans. Thirty-seven different fatty acids were determined from A. caesarea, and oleic acid (58%) was the dominant component. Discussion and conclusion: Amanita caesarea had a high-antioxidant and -antimicrobial activity, and it also had important essential fatty acids required for human health. According to the results, this mushroom can be recommended as a major source of natural food.

    (Humana Press Inc, 2006) Doğan, Hasan Hüseyin; Şanda, Murat Aydın; Uyanöz, Refik; Öztürk, Celaleddin; Çetin, Ümmühan
    The concentrations of 7 metals (lead, cadmium, manganese, copper, nickel, silver, and chromium) were determined in 32 different species of wild Mushrooms. The mushroom samples, which have been using for food and some medical purposes, were collected from Konya, an Inner Anatolian region of Turkey. The highest metal concentrations were determined as 39 mg/kg Pb and 3.72 mg/kg Cd in Trichaptum abietinum, 467 mg/kg Mn in Panaeolus sphinctrinus, 326 mg/kg Cu in Trametes versicolor 69.4 mg/kg Ni in Helvella spadicea, 6.97 mg/kg Ag in Agaricus campestris, and 84.5 mg/kg Cr in Phellinus igniarius. The maximum contents are 1.52, 2.22, and 60.2 mg/kg in Pleurotus eryngii (for Pb), Amanita vaginata (for Cd), and Helvella leucomelana (for Cu), respectively. These results were compared according to the WHO/FAO standard.

    Determination of multiple antioxidant activities of endemic tricholoma anatolicum
    (2018) Taşkın, Hatıra; Eker, Tülin; Bozok, Fuat; Doğan, Hasan Hüseyin; Büyükalaca, Saadet
    Tricholoma anatolicum H.H. Doğan & Intini is known as the most prized mushroomspecies in Feke region of Turkey. This mushroom species is collected from Cedar(Cedrus libani) forests and therefore is named as Cedar mushroom in this region. It iscollected and consumed by local collectors and also exported to Far East countries suchas Japan by exporting companies. Therefore, it is important to investigate the nutritionaland medical importance of this species. The aim of this study is to reveal the antioxidantactivity of methanol extract in different concentrations (1, 2 and 4 mg/mL) of T.anatolicum H.H. Doğan & Intini collected from Feke district of Adana province ofTurkey in 2015. In this study, it was determined that total phenolic content of thismushroom was 56 mg/kg. 2,2-diphenyl-1-picrylhydrazyl (DPPH), nitric oxide (NO) andreducing power (RP) activities given in trolox (?M) and ferric-reducing antioxidantpower (FRAP) given in FeSO4 (?M) were found as 449, 180, 337 and 2 at the highestconcentration (4 mg/mL), respectively. As a result, it could be suggested that methanolextract of T. anatolicum H.H. Doğan & Intini has significantly antioxidant activity.

    Ecology and Distribution of Two Parasitic Fungal Species (Pyrofomes Demidoffii and Antrodia Juniperina) on Scale-Leaf Juniper Trees in Turkey
    (Adac-Cryptogamie, 2006) Doğan, Hasan Hüseyin; Karadelev, Mitko
    Pyrofomes demidoffii and Antrodia juniperina, two important parasitic fungal species on Juniperus excelsa and J. foetidissima were studied on 22 localities in Turkey where its associations are best developed. The investigation into the ecology and distribution of these two poroid species was carried out during a period of two years, between October 2003 and November 2004. The fungi are presented in the paper, and their role in juniper ecosystems is discussed herewith. This is the second find of the species Antrodia juniperina in Turkey. Since the investigations were conducted only in some of the known localities, mostly in the western, southern and central parts of the country, many more data are expected to be obtained in the future research.

    Identification of wood-decay fungi and assessment of damage in log depots of Western Black Sea Region (Turkey)
    (WILEY, 2019) Yalçın, Mesut; Doğan, Hasan Hüseyin; Akçay, Çağlar
    The aim of this study was to determine and quantify the wood-decay fungi found on logs of forest tree species (beech, oak, hornbeam, Scots pine and fir) stored in log depots located in six different provinces in the Western Black Sea Region of Turkey. Additionally, it was aimed to determine the natural durability of some important wood species against the most commonly detected wood-decay fungi. Eighteen families, 31 genera and 45 species belonging to the division Basidiomycota were detected; Antrodia crassa was identified for the first time in Turkey. The abundance of Panus neostrigosus, Polyporus meridionalis, Trametes hirsuta, T.versicolor and Stereum hirsutumincreased significantly with the holding time of the logs (r=0.99, 0.87, 0.53, 0.57 and 0.78, respectively, p<0.05). The majority of the fungal species were detected on logs stored in depots for 4-6years (66%). The percentage of fungal species found on the logs with a holding time of three years or less was 29%, whereas the percentage for those detected on logs stored for seven or more years was 31%. Among the wood species, the greatest number of fungal species (29) and highest amount of fungi (2,539) occurred on beech wood. Natural durability tests showed that T.versicolor caused the greatest loss of wood mass, with an average of 23%. Field studies and natural durability tests performed in the laboratory showed that beech wood lost the most mass among the timber species studied.

    In vitro Antioxidant Activity of Enteromorpha intestinalis (Linnaeus) Nees
    (ASIAN JOURNAL OF CHEMISTRY, 2009) Akköz, Cengiz; Tekeli, Yener; Doğan, Hasan Hüseyin
    In this study, antioxidant activity of Enteromorpha intestinalis was determined by three different methods. Total phenolic concentration of the extracts was estimated with Folin-Ciocalteu reagent using gallic acid as standard. Free-radical scavenging activities were determined based on 1,1-diphenyl-2-picrylhydrazyl radical (DPPH). The copper(II) ion reducing ability of polyphenols is measured by CUPRAC method. Results were compared with standard butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA).

    Investigation of antioxidant potential and phytotoxic effects of ganoderma lucidum methanol extract
    (2016) Bozok, Fuat; Eker, Tülin; Sezer, Gökhan; Bozdoğan, Adnan; Doğan, Hasan Hüseyin; Büyükalaca, Saadet
    The aim of this study is to reveal allelopathic effects and antioxidant activities of methanolic extract of Ganoderma lucidum in Zorkun plateau (Osmaniye). It was determined that methanolic extract of G. lucidum has significantly phytotoxic effect by increasing the doses (1, 2, 4, 8 mg/mL) on Hordeum vulgare and Triticum aestivum. Total phenol and flavonoid amounts of G. lucidum were 114.55 mg/kg and 8.95 mg/kg, respectively. 2,2-diphenyl-1-picrylhydrazyl (DPPH), scavenging activity (60%, 91% and 92%), reducing power (0.83, 1.43 and 2.23 Abs), and nitric oxide (NO) scavenging activity (48%, 55% and 70%) of this mushroom at the different concentrations (1.25, 2.5 and 5 mg/mL) were determined, respectively. However, H2O2 scavenging activity of the different concentrations (0.0156-0.125 mg/mL) was found as 18%, 56%, 60% and 86%, respectively. Based on these findings, it can suggest that G. lucidum methanolic extract has significantly phytotoxic effect and antioxidant activity. The present study is the first report on the phytotoxic effects and antioxidant activities of G. lucidum which consumed and collected from Amanos Mountains.
