摘要:In this study, the antioxidant and antimicrobial activity of Origanum acutidens (Hand.-Mazz.) Ietsw. collected from Sivas (Turkey) was determined. Rel Assay Diagnostics kits were used to determine TAS, TOS and OSI values. Antimicrobial activity was determined on 9 different bacteria and fungi (Staphylococcus aureus, S. aureusMRSA, Enterococcus faecalis,Pseudomonas aeruginosa, Acinetobactermannii, Candida albicans, Candida krusei, andCandida glabrata) using the modified agar dilution method. As a result of the studies, it was determined that O. acutidens has high antioxidant potential. The extracts were found to be effective on test microorganisms at the concentrations of 25-100 (ig/mL. As a result, it was determined that acutidens has high antioxidant and antimicrobial potential and can be used as a natural source with high therapeutic quality.
