Abstract :
Results of chemical composition analysis by CG-MS of essential oils of Thymus satureioides Cosson extracted by hydrodistillation from leaves samples collected in four locations of Taroudante region (Southwest Morocco), identified fifty components representing over than 98%. The major constituent was borneol with proportions ranging between 33.03 and 41.80%. Essential oils yields varied from 1.35 to 2.32% and were positively correlated with an altitude gradient. Four chemotypes were then distinguished according to the collection site. The antifungal activity of essential oil of this thyme against four wood-decaying fungi, assessed by direct contact on agar medium, showed that 1/500 concentration (v/v) of all EOs was sufficient to inhibit the growth of all tested fungal strains. These results suggest that this oil can be used as wood preservative against wood-destroying fungi.
