GC-MS Analysis and Antibacterial Activity of Cultivated Satureja cuneifolia Ten.Essential Oil

摘要

The composition of the essential oil of Satureja cuneifolia Ten.cultivated in Konya,Turkey,was investigated by capillary GC-MS.The compounds were characterized by comparison with library searches.Six main compounds were identified.Carvacrol was the dominant component,comprising 59.28% of the essential oil.The oil also contained 15.72% thymol,9.69% p-cymene,4.16% gamma-terpinene,1.70% linalool and 1.25% borneol.The antibacterial activity of the essential oil of S.cuneifolia and its components was determined by a semiquantative disc-diffusion method,and the minimum inhibitory concentration(MIC)was determined based on a micro-well dilution method against strains of Pseudomonas aeruginosa,Bacillus cereus,Sarcina lutea,Escherichia coli,and Staphylococcus aureus.
