Ten plants (Salvia sclarea, Achillea millefolium, Nigella sativa, Linum usitatissimum, Origanum onites, Salvia officinalis, Mentha piperita, Lavandula officinalis, Melissa officinalis and Rosmarinus officinalis) were tested for their antioxidant activity by their interaction with 2,2-diphenyl-1-picrylhydrazyl (DPPH) and total phenol. Methanolic leaf extracts of Sage and mint (DPPH scavenging activities) showed more stronger activities. These antioxidant properties depended on concentration of sample. The lowest and highest antioxidant values of Salvia sclarea and Salvia officinalis extracts were found as 82.14% and 84.98 %” respectively. While the lovest total phenol was established in Nigella sativa (1.059 mg Gallic Acid Equivalent/100 ml), the highest level was found in Melissa officinalis (3.609 mg Gallic Acid Equivalent /100 ml).
