Sažetak
The yield of essential oil obtained by hydrodistillation from aerial parts of Micromeria thymifolia (Scop.) Fritsch varied from 0.3% to 0.5% (V/m) during the vegetation period. The oils were characterised by a very high content of oxygenated monoterpenes (90.2-96.5%). Other components were monoterpene hydrocarbons and sesquiterpenes. Piperitenone oxide, pulegone and piperitone were identified as the major components of the investigated oils (GC, GC-MS). Significant seasonal variations in the relative amounts of the main components were confirmed. A continuous reduction in the oxide fraction with an accompanying increase in the proportion of ketones was observed.
