Variability of Essential Oil Composition of Origanum vulgare L. subsp gracile Populations from Turkey

The aerial parts of fifteen different populations of O. vulgare L. subsp. gracile were investigated to determine their variability among essential oil compositions. Thymol, carvacrol, gamma-terpinene and p-cymene were detected as the major components of all population samples in different amounts. Almost all populations had the same essential oil contents, except for minor differences. The most abundant components were thymol and carvacrol.
