Abstract
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 fro m four regions - Bale, Gender, Shewa, and Wello - were identified as p-cyme ne (9-23%), gamma -terpinene (8-17%), thymol (6-38%) and carvacrol (5-63%). The oil from T. serrulatus was found to contain p-cymene (13%), gamma -ter pinene (13%) and thymol (49%) as major components. Both species belong to t he thymol-carvacrol chemotypes.
