SPME/GC-MS Analysis of Volatile Organic Compounds from three Lamiaceae Species (Nepeta conferta Hedge & Lamond, Origanum onites L. and Satureja cuneifolia Ten.) Growing in Turkey

Solid phase microextraction of Nepeta conferta Hedge & Lamond, Origanum onites L. and Satureja cuneifolia Ten., three Lamiaceae species to Turkey, were analyzed by GC-FID/MS. The main components of the volatile organic components were: p-cymene (25.5 %), eucalyptol (9.8 %), limonene (5.0 %), sabinene (4.8 %), carvacrol (3.7 %), E-linalool oxide (3.3 %), Z-linalool oxide (3.0 %) in N. conferta; carvacrol (47.3 %), p-cymene (15.8 %), γ-terpinene (8.6 %), myrecene (8.6 %), caryophyllene (2.0 %) in O. onites and carvacrol (32.6 %), p-cymene (22.2 %), γ-terpinene (15.1 %), myrecene (5.5 %) and caryophyllene (3.3 %) in S. cuneifolia. Carvacrol was the most abundant component in volatile organic compounds of O. onites (47.3 %), S. cuneifolia (32.6 %) and N. conferta (3.7 %).
