Water distilled essential oils from aerial parts of Galium aparine and Galium odoratum collected from Ankara and Kastamonu were analyzed by GC/MS. Seventy-two compounds representing 64.7% of the essential oil G. aparine, and 96 compounds representing 89.1% of the essential oil G. odoratum were characterized. The major component of the essential oil obtained by acid hydrolysis from G. aparine was hexadecanoic acid (22.3%), whereas the major components of the essential oil of G. odoratum were thymol (30.6%) and isothymol (22.8%). Therefore, we do not consider G. aparine an aromatic plant as the oil contained predominantly fatty acids and four terpenoids.
