ABSTRACT
Essential oil content and composition of wild growing Thymus kotschyanus Boiss. & Hohen. were evaluated in response to different harvest time (pre-flowering or vegetative, flowering and post-flowering stages) and wild habitat altitude (1400, 1600 and 1800 m above sea level). The results showed that the highest essential oil content (2.9%) belonged to the flowering stage at 1600 m altitude. GC and GC/MS analysis of essential oil revealed that carvacrol (4.2- 49.1%) and thymol (2.6-13.3) were the predominant constituents of volatile oils. Other common major components were α-terpineol, p-cymene, 1,8-cineole, borneol, camphor, γ-terpinene and linalool. Geraniol (17.8%) had considerable amounts possessed by plants harvested from 1400m during vegetative stage. Taking into account the essential oil content and, carvacrol and carvacrol + thymol percentage amounts it seems that flowering stage at 1600m is the most appropriate harvest time for this plant from its wild habitat. However, considering other major components, any of nine treatment combinations have the potential suitability for the utilization of their volatile constituents in the related industries.
