Essential Oil Composition and Antibacterial Activity of Nepeta glomerulosa Boiss from Iran

The chemical compositions of the essential oil of Nepeta glomerulosa Boiss aerial parts, grown in Iran were determined by GC-MS. Fifty-two compounds (97.2 %) were determined. The major compounds were geranyl acetate (17.0 %), limonene (12.0 %), eucalyptol (5.8 %), (bornyl acetate (5.3 %), citronellal (4.9 %), spathulanol (4.2 %), sabinene (3.9 %), beta-ocimene (3.9), beta-sesquiphellandrene (2.8 %), neryl acetate (2.5 %), alpha-humulene (2.4 %), alpha-pinene (2.3 %), humulene oxide (2.2 %), norsolanadione (2.1 %) and terpinen-4-ol (2.0 %). The yield of the oil was 1.1(v/w) %. The essential oil showed antibacterial activity for Staphylococcus aureus.
