Salvia belongs to the Lamiaceae family and includes nearly90 species in Turkey. Salvia generally is used for treatment ofcolds, bronchitis and epilepsy. It is commonly consumed as a hotdrink. In the current study, ethyl acetate extract ofSalvia tomen-tosawas investigated for its free radical scavenging capacity usingthe 2,2-diphenyl-1-picryl hidrazyl (DPPH) method and its antioxi-dant property was evaluated. Moreover, the extraction procedureapplied toSalvia tomentosayielded a calculated 5.13%. Its scaveng-ing capacity ranged between 0.03 and 1.7 mg/mL and ethyl acetateextract ofS. tomentosahas represented the minimum scavengingactivity of nearly 3% at 0.03 mg/mL and the maximum scaveng-ing activity of 71% at 1.67 mg/mL. The free radical scavengingeffective concentration (EC) ofSalvia tomentosawas found to be0.91±0.005 mg/mL. In conclusion, it can be used as medicinal plantwith antioxidant property for further investigation.
