In this study antimicrobial and antioxidant effect of methanolic and aqueous extracts of Salvia przewalskii seed oil were tested against four strain of bacteria (Streptococcus bovis, Proteus mirabillis, Enterococcus gallinarum, Escherichia coli) and two strain of fungi (Rhizopus oryzae and Rhizopus stolonifer). Aqueous and methanolic extracts of Salvia przewalskii seed oil were prepared by solvent extraction, the results showed the hydro distillation of seed parts of S. przewalskii in vitro yellow oils in dry weight ( 0.3% and 0.5 % (v/w; ml 50 g) products, antibacterial data showed higher ability towards E.coli (26.67±0.89) compared with standard streptomycin (22.78±0.49) and highest inhibition zone measured 25 mm . as well as methanol extract at (200mg/ml) recorded highest antioxidant ability (86.87±0.76) and DPPH scavenging activity at 20 μl/ml (89.56±0.47).
