Abstract Water distilled essential oils from aerial parts of Nepeta sessilifolia Bunge, and Nepeta haussknechtii Bornm. were analyzed by GC and GC/MS. Thirty-three compounds representing 97.4% of the oil of N. sessilifolia, and 27 compounds representing 94.2% of the oil of N. haussknechtii were characterized. The major components of the essential oil of N. sessilifolia were linalool acetate (14.7%) and linalool (14.2%), whereas the major components of the oil of N. haussknechtii were 1,8-cineole (36.7%) and elemol (11.4%). Both oils were richer in oxygenated monoterpenes than sesquiterpenes.
