Analysis of the essential oil of <i>Thymus eriocalyx</i> from Iran

Abstract

Abstract Essential oils isolated by hydrodistillation from the aerial parts of Thymus eriocalyx (Ronniger) Jalas, before flowering and full flowering stage, were analysed by a combination of capillary GC and GC–MS. Seventy components were identified, constituting approximately 92.5% of the oil. The main constituents of the essential oil were thymol (42.8% and 43.1%), linalool (11.1% and 4.0%), γ ‐terpinene (6.0% and 6.3%), 1,8‐cineole (5.6% and 3.3%), borneol (3.4% and 4.9%) and α ‐terpineol (1.8% and 7.1%) at before flowering (10 days before bloom formation) and full flowering stage, respectively.
