ABSTRACT = {<i>Salvia microphylla</i> and <i>Teucrium polium</i> are medicinal and aromatic plants with ethnobotanical uses. The present study was conducted to investigate the chemical composition of <i>Salvia microphylla</i> and <i>Teucrium polium</i> essential oils, the secondary metabolites, and the biological activities of their infusion and methanolic (MeOH) extracts. Essential oils were extracted by hydrodistillation from shoots <i>Salvia microphylla</i> and <i>Teucrium polium</i>. Phenolic content, antioxidant and antimicrobial activities were determined. Gas chromatography-mass spectrometry (GC-MS) results showed the presence of significant qualitative and quantitative variations for the composition of the both essential oils (EO). <i>Salvia microphylla</i> EO were most complex and present 70 compounds with the major components were β-caryophyllene (13.32%), 1,8 cineole (11.25%), Cis p-Menthane-3-one (10.74%), and β-Selinenol (9.71%). Where in the <i>Teucrium polium</i> EO, 45 compounds were identified with the important components are β-cadinene (10%), β-citronellol (8.5%), Carvacrol (7.63%), and Eugenol (7.15%). Obtained results showed that both plant are very rich in secondary metabolites. Extracts isolated from <i>Salvia microphylla</i> presented the highest contents in the phenolic compound than extracted from <i>Teucrium polium</i>. The antioxidant activity data demonstrated that all extracts showed strong antioxidant and radical scavenging activities. Essential oil and methanol extracts presented a potential for antimicrobial activities against all tested microorganisms. The obtained results highlight the potential use of <i>Salvia microphylla</i> and <i>Teucrium polium</i> as possible natural antioxidant substances and sources of bioactive molecules.},
