Origanum sipyleum L. (Labiatae) was collected from four different locations in Turkey. The volatile oil of each sample was obtained by hydrodistillation and analyzed by GC and GC/MS. Forty-eight compounds were identified in the oils of which γ-terpinene (10.80–26.60%), p-cymene (3.76–36.60%), thymol methyl ether (trace-19.90%), carvacrol methyl ether (0.41–10.20%), thymol (0.23–7.30%) and carvacrol (0.82–12.20%) were found to both occur in greatest abundance and to vary the greatest. © 1992 Allured Publishing Corp.
