Özet: Asphodelus ramosus known as a yellow lily which has been a plant of onion for this reason, this plant was studied with about antioxidant activity of methanol, 50 % methanol, ethyl acetate and water extracts. The plant was dried at two different temperatures (35 ºC and 65 ºC) so as to understand how to work the difference in temperature effects. After extraction, all solvent extracts were studied for their total phenolic contents using Folin Cioceltau reagent, total flavonoid content with aluminum nitrate method. In addition, DPPH free redical scavenging through the determination, the determination of the activity of removal of H2O2, copper (II) ion reducing antioxidant capacity determination (CUPRAC), removal activity of super oxide anion were studied and the results were supported with HPLC (High Performance Liquid Chromatography).
