The present study was designed to evaluate the antioxidants compound and activities in Salvia officinalis, Mentha spicata, Lavandula angustifolia, Satureja hortensis and Origanum vulgare methanol extracts. Antioxidant activities of plant extracts were assessed using 1, 1-diphenyl-2-picrylhydrazyl (DPPH) and ability to reduce Fe3+ to Fe2+ assay. Free radical scavenging activity of S. officinalis was recorded as high as 90.1% followed by L.angustifolia (88.7%) at 300μg/ml. This value was found close to the activity of synthetic antioxidant, butylated hydroxytoluene (BHT) (94.0%) at the same concentration. In this study, Salvia officinalis and L. angustifolia had higher total phenolic contents (21.7 ± 1.18 and 19.2 ± 1.06mg GA/100g DW) whereas S. officinalis had the largest flavonoid contents (4.8 ± 0.12mg CE / 100g DW). Results showed strong correlation between antioxidant activity and carotenoids content (r=0.82), phenolic compounds (r= 0.92), vitamin C (r= 0.81), vitamin E (r= 0.79) and tannins content (r= 0.81). It can be concluded from the current results that antioxidative potency of L. angustifolia and S. officinalis is attributed to the presence of higher contents of biocompound like carotenoids, phenolics, vitamins and flavonoids.
