The composition of the essential oils of Nepeta crispaWilld. and N. MENTHOIDES Boiss. and Buhse (Lamiaceae) was investigated by means of gas chromatography (GC) and GC- mass spectrometery (MS). 1, 8-Cineole was the most abundant component in oils: Nepeta crispa (71%) and N. MENTHOIDES (41.1%). In the oil of N. crispa, b-pinene (5%) and d-terpineol (4.1%) were found to be the major constituents. Dihydromyrcen-1-ol (9.2%), 4-terpineol (7.1%), and geranyl acetate (6.1%) were the predominant compounds in the oil of N. MENTHOIDES.
