AIT-MIMOUNE, Nouara; KADA, Fatima  e  DRIDER, Houda. Antimicrobial and Antioxidant activities of Algerian Juniperus phoenicea and Salvia officinalis Essential Oils. J. Mex. Chem. Soc [online]. 2023, vol.67, n.2, pp.122-129.  Epub 23-Mar-2024. ISSN 1870-249X.  https://doi.org/10.29356/jmcs.v67i2.1921.

In this work, the chemical composition, antioxidant and antifungal activities of Juniperus phoenicea and Salvia officinalis essential oils (Eos) were evaluated. The Gas Chromatography-Mass spectrometry (GC-MS) identification of S. officinalis Eo revealed the predominance of cis-chrysanthenyl acetate (64.82 %), and α- thujone (14.7 %). The main compounds of J. phoenicea oil were α-Pinene (64.4 %) and δ-3-Carene (7.02 %). The antibacterial activity was evaluated using the agar well diffusion method. The most susceptible bacteria was Staphylococcus aureus. The antifungal activity was tested against Aspergillus and Penicillium species by the poisoned food method. The two essential oils (Eos) exhibited an antifungal activity, with S. officinalis oil being the most potent one (8-82 % of inhibition). The antioxidant activity was characterized by the DPPH free radical scavenging method. J. phoenicea and S.officinalis Eos had both a moderate antioxidant effect. Additionally, an antagonistic effect was observed between the Eos when used in combination.
