In the present study, we reported the essential oils chemical composition and antibacterial activities of the aerial parts of Ajuga chamaecistus Ging. ex Benth. Subsp. Scoparia (Boiss.) Rech.f. thatwere collected duringMay ۲۰۱۳ and April ۲۰۱۴ and extracted by SDE (simultaneous distillation–extraction) and Clevenger apparatus. GC/MS analysis of the plant essential oils led to the identification of chemical composition of its oils. The main constituents of the essential oils in two SDE (simultaneous distillation–extraction) and Clevenger apparatus were β-Pinene (۲۳.۵%), α-Pinene (۶.۹%), Limonene (۱۰.۸%), Linalool (۸.۳) and Eugenol (۷.۷%). Essential oil was tested for their antibacterial activities using Gram-negative bacteria, Gram-positive bacteria. The plant was screened for its antibacterial activity and showed antibacterial activity against P. aeruginosa, E. coli, K. pneumoniae, P. vulgaris, S. paratyphi, B. subtilis, S. aureus, S. epidermidis and S. dysenteriae.
