    Antioxidant and Antimicrobial activity of Scorzonera papposa collected from Iraq and Turkey
    (Kahramanmaras Sutcu Imam Univ Rektorlugu, 2020) Mohammed, Falah Saleh; Gunal, Salami; Sabik, Ali Erdem; Akgul, Hasan; Sevindik, Mustafa
    Plants are important natural materials used in complementary medicine. In this study, antioxidant and antimicrobial activities of Scorzonera papposa DC. collected from Duhok (Iraq) and Gaziantep (Turkey) regions were determined. Extracts of aerial parts and roots of the plant with ethanol were obtained. Antioxidant and oxidant potentials were determined by using Rel Assay Diagnostics kits. Antimicrobial activities were tested against bacteria and fungus strains using the agar dilution method. In our study, it was determined that S. papposa has important antioxidant activity. Also, It was found that extracts of plant parts were effective at 50-800 mu g/mL concentrations. As a result, it was determined that S. papposa could be a natural antioxidant and antimicrobial agent that can be used in complementary medicine.

    Phenolic Content, Antioxidant and Antimicrobial Potential of Endemic Ferulago platycarpa
    (Gazi Univ, 2020) Mohammed, Falah Saleh; Gunal, Selami; Pehlivan, Mustafa; Dogan, Muhittin; Sevindik, Mustafa; Akgul, Hasan
    In this study, biological activities and phenolic contents of endemic Ferulago platycarpa Boiss. & Bal. were determined. Within the scope of biological activity, antimicrobial activity, antioxidant and oxidant status of plant extracts were determined. Phenolic contents were determined by using HPLC. Antimicrobial activity was determined against bacteria and fungus strains using the modified agar method. Antioxidant and oxidant status were calculated with Rel Assay kits. Gallic, chlorogenic, cinnamic, syringic acids, epicatechin, catechin and quercetin were found in the plant. It was also determined that the plant has antioxidant and antimicrobial potential. But, because of higher TOS value, it was considered that the plants, which were collected from region suitable for OSI value, could be a natural antioxidant source.
