Asteraceae) 9 14 EN Mahfuz Elmasta? Gaziosmanpa?a University, Faculty of Science and Arts, Department of Chemistry 60240-Tokat-Turkey Sed ?inkili? Hassan Y. Aboul-Enein WJAC201531A3 10.12691/wjac-3-1A-3 2015 04 19 2015 07 28 2015 09 06 Daisy is a medicinal plant which is used for treating several diseases. This investigation describes the antioxidant capacity of different parts of daisy, collected from Tokat-Turkey, using various antioxidant assays. It was understood that all parts (flower, stem, and whole herb) of daisy have antioxidant activity. It was determined that there is extra activity of reduction power in the whole herb, extra activity of scavenging of superoxide anion radical in the stem of the plant, extra activity of total antioxidant activity in the whole herb, extra activity of metal chelating activity in the flower, but there is almost equal activity of scavenging free radical in the flower, in the stem and in the whole herb. In addition, total phenolic compounds were analyzed. The concentration of total phenolic compounds was 29.4 µg kg-1 dry weight in the flower, 22.3 µg kg-1 dry weight in the stem, and 32.1 µg kg-1 dry weight in the whole herb.
