This study was designed to examine the in vitro antioxidant DPPH free radical-scavenging activity, and the total phenolic and flavonoid content of ethanol and methanol extracts of Salvia amplexicaulis Lam. in the whole plant and different parts, leaves, stems and flowers. The largest amounts of extract yield were obtained from the flowers, 14.14% and 12.00 % (w/w) in the ethanol of methanol extracts, respectively. The ethanol extract of leaves (16.07 μg/ml) and methanol extract of the whole plant (21.28 μg/ml) showed the highest activity against the DPPH radical. The ethanol extract of the leaves was the richest in phenols (222.40 mg GAE/g) and flavonoids (49.81 mg QE/g), whereas the methanol extract of the whole plant contained the highest amount of phenolics (180.89 mg GAE/g) and flavonoids (38.15 mg QE/g). A very strong linear correlation between antioxidant activity and the phenolic content of the extracts was established. The obtained results suggest that S. amplexicaulis could be regarded as an important source of natural antioxidants. [Projekat Ministarstva nauke Republike Srbije, br. 173029
