| Summary: | In this study, the antioxidant and antimicrobial potentials of the ethanol extract of the aerial parts of Lepidium spinosum Ard., which is distributed in many regions of the world, were determined. The aerial parts of the plant were dried, powdered and extracted with ethanol. Total antioxidant status (TAS), total oxidant status (TOS) and oxidative stress index (OSI) of the plant extract were determined using Rel Assay Diagnostics kits. Antimicrobial activities of the plant extract were determined against standard bacterial and fungal strains by agar dilution method. As a result of the studies, the TAS value of the plant extract was determined as 4.550±0.132, the TOS value as 12.610±0.221, and the OSI value as 0.277±0.007. In addition, it has been found to be effective at 25-200 µg/mL against standard bacterial strains and 100-200 µg/mL concentrations against fungal strains. As a result, it was determined that L. spinosum used in our study could be a natural antioxidant and antimicrobial source. In this context, it is thought that natural material may be used in pharmacological designs.
