Abstract
Plants are widely used in the treatment of various diseases. The present study evaluates for the first time the potential antioxidant and antimicrobial activities as well as the total flavonoid contents of the ethanol extracts of leaf and flower parts of G. gracilis Celak. species distributed in Muğla province. The antioxidant activities were determined by DPPH, ABTS and β-carotene assays. The antimicrobial activities were evaluated by the disc diffusion method and by determining the minimal inhibitory concentration (MIC). According to the outcomes from DPPH and β-carotene assay, the ethanolic flower extract may be suggested to have a higher antioxidant potential than that of the leaf. The total flavonoid content was found in the highest in the ethanolic leaf extract. Gram (-) P. aeruginosa was detected as the most sensitive bacteria to both extracts. C. albicans was determined to be more sensitive to both extracts compared to all tested bacteria. These results suggest that G. gracilis possess potential antioxidant and antimicrobial activity.
