    (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.

    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.
