Özet
In this study, the antioxidant and antimicrobial effects of petroleum ether, hexane, ethyl acetate and methanol extracts of Hypericum retusum Aucher are investigated. The antioxidative potential of H. retusum extracts was examined using different antioxidant tests, including the total amount of phenolic components (Folin & Ciocalteu reagent method), total amount of flavonoids, 1,1-diphenyl-2-picryl hydrazyl (DPPH)) radical scavenging, metal chelating, reducing power, and hydroxyl radical activities. At the same time, antimicrobial effects were examined in 6 types of bacteria (Escherichia coli ATCC 25922, Staphylococcus aureus ATCC 25923, Staphylococcus pyogenes ATCC 19615, Bacillus subtilis ATCC 11774, Bacillus cereus, Pseudomonas aeruginosa ATCC 27853). It has been observed from the experiments that extracts of H. retusum have high antioxidant effects and in addition, antimicrobial activity on bacteria.
