the present work is targeted to evaluate antioxidant activity of ethanol extracts from the leaves of plectranthus mollis and salvia officinalis belonging to family lamiaceae using nitric oxide scavenging , hydrogen peroxide scavenging , ferric reducing antioxidant power assay and lipid peroxidation methods . 
 the results of the study indicate that the leaf extracts of both the plants possess in vitro antioxidant activity . 
 the higher amount of flavanoids and phenolic compounds may correspond to their greater antioxidant activity .
