Popis:	The chemical composition of four Thymus species essential oils (T. capitatus, T. ciliatus, T. bleicherianus and T. algeriensis) was determined by GC and GC/SM. The essential oil of T. capitatus is dominated by carvacrol (70.92%), that of T. ciliatus by thymol (44.2%), that of T. bleicherianus contains α-terpinene (42.23%) and thymol (23.95%) as major chemical constituents, while that of T. algeriensis is formed mainly by camphor (27.7%) and α-pinene (20.5%). The antioxidant activity was determined by the DPPH test. The essential oil of T. capitatus, T. ciliatus and T. bleicherianus show strong antioxidant activity with (IC50 = 69,04 μg/ml, 74,025 μg/ml and 77,8 μg/ml) respectively, compared to the essence of T. algeriensis and other species of thyme in the literature.
