Öğe Investigation of Antioxidant Effect of Origanum Hypericifolium Extracts in Different Solvents(Sivas Cumhuriyet Üniversitesi, 2025) Sufi, Muhammed; Özsoy, Ceylan; Çiçek, MehmetOriganum hypericifolium is one of the most widely distributed endemic species of the family Lamiaceae. Origanium hypericifolium contains mostly monoterpenes. Monoterpenes are volatile compounds with 10 carbons and are widely found in the plant kingdom. Monoterpenes, which are used as fragrances in perfumes and foodstuffs, have anti-fungal, anti-bacterial, anti-oxidant and anti-cancer effects.Various in vitro assays can be used to determine the antioxidant activity of Origanium hypericifolium extracts. In our study, total polyphenolic, total flavonoid content, iron reducing power, cupric ion reducing capacity and radical scavenging activity were evaluated to the antioxidant properties of various extracts of Origanum hypericifolium. TAS and TOS levels were also analyzed. The highest DPPH radical scavenging acitiviy value was 3.09±0.01 µg/mL in ethanol extract, Total polyphenol 144.00±1.89 µg GAE /g in ethanol extract, Total polyphenol 17. 08±0.85 µg CE /g in ethanol extract, FRAP 942.46±1.89 µg TE /g ethyl acetate and CUPRAC 2.54±0.01 mmol TE/g ethyl acetate extract.
