Popis:	The volatile oils from Thymus schimperi Ronninger and T. serrulatus Hochst. ex Benth. (Lamiaceae) grown in Ethiopia, have been examined by means of GC and GC–MS. The main constituents of the essential oils of T. schimperi from four regions — Bale, Gonder, Shewa, and Wello — were identified as p-cymene (9–23%), γ-terpinene (8–17%), thymol (6–38%) and carvacrol (5–63%). The oil from T. serrulatus was found to contain p-cymene (13%), γ-terpinene (13%) and thymol (49%) as major components. Both species belong to the thymol–carvacrol chemotypes.
