AB  - This work uses GC-MS to analyze the bioactive compounds of <i>Salvia rosmarinus</i> essential oils (SREO) and evaluates their antibacterial, antifungal, and insecticidal effects, as well as the major component, 1,8-cineole. Chemical analysis identified 16 compounds accounting for 99.19% of the oil’s total content, with 1,8-cineole (33.17%), camphor (16.53%), α-pinene (14.46%), and camphene (8.14%) as the major constituents. Antimicrobial activities were assessed against pathogenic strains using minimal inhibit concentration (MIC) and minimum bactericidal concentration (MBC) assays. SREO exhibited a minimum MIC of 0.128% against <i>P. aeruginosa</i>, while 1,8-cineole showed a minimum MIC of 2.06% against the same strain, highlighting the higher efficacy of the complete oil compared to the isolated compound. Conversely, for antifungal activity, 1,8-cineole displayed a lower MIC (2.06%) against <i>A. niger</i> and <i>P. digitatum</i> compared to SREO (4.125% against <i>A. niger</i>). Regarding aphicidal activity, results demonstrated the lethal effects of SREO on <i>M. persicae</i>, with an even more pronounced impact observed for 1,8-cineole. At one dose of 40 μL/L air, SREO and 1,8-cineole resulted in 100% insect mortality within 24 h of exposure. After 12 h of exposure to SREO at concentrations of 5, 10, 20, and 40 μL/L air, the mortality rates were 20%, 36.67%, 70%, and 93.33%. 1,8-cineole showed maximum efficacy, achieving complete (100%) mortality within 12 h at 40 μL/L air.
