Gas chromatography\u2013mass spectrometry identified 49 constituents in the EOs, representing 97.9%\u201398.5% of total compositions. Sesquiterpene hydrocarbons predominated in all the samples (41.3\u201387.1%), with \u03b2\u2010bisabolene as the most abundant compound (23.8\u201353.7%). Bioactivity evaluation revealed that all the EOs showed dose\u2010dependent inhibition of \u03b1\u2010amylase and tyrosinase.

Antioxidant assays indicated moderate radical scavenging effects, with LEO and REO showing the highest activity in the DPPH and ABTS assays, respectively, though all were considerably weaker than ascorbic acid. Antibacterial evaluation against five pathogenic bacteria demonstrated that REO possessed the highest activity and inhibited all strains. LEO showed moderate inhibition, whereas SEO displayed the weakest activity and lacked activity against\n                    <jats:italic>Pseudomonas aeruginosa<\/jats:italic>\n                    .
