Data showed an average yield of about 2%. The analysis of the oil components was carried out by GC-FID and GC/MS. The main oil constituents were thymol (36.3–47.5%), p-cymene (13.0–27.8%) and γ-terpinene (5.3–16.2%), which is in accord with a thymol chemotype. The highest yield of oil was obtained in the period of full flowering and the highest concentration of thymol in the period of initial flowering.
