Abstract: Thymus ciliatus ssp. eu-ciliatus harvested in western Algeria produces an essential oil whose composition is
dominated by carvacrol (72.4–80.3%). The oil displayed antimicrobial activity.
All species of Thymus genus (Labiatae family) produce an essential oil, and several representatives are important herbs and spices used in all part of the world. To date, the oils of 162 taxa of the Thymus genus have been chemically investigated revealing about 360 volatiles components in total and wide essential oil polymorphism. The phenolic terpenes, thymol and carvacrol, rank highest in importance (1).
