Essential oils from the flowers, bracts and leaves of Tilia platyphyllos Scop., T. rubra DC. and T. argentea Desf. ex DC. growing in Turkey were examined by GC/MS. The composition of the essential oils showed differences. The essential oils from the flowers of T. platyphyllos and T. rubra were characterized by a high percentage of hydrocarbons (47.5-66.5%), whereas T. argentea flowers were rich in esters (34.8%). Esters were also in high amount in the bracts of T. argentea (27.0%). The high content of aliphatic acids were found in the all parts of T. platyphyllos (28.3-37.1%), T. argentea (29.4-41.0%) and bracts of T. rubra (30.8%). Kaur-16-ene (29.3% and 41.9%) was the major constituent in the leaf oils of T. rubra and T. platyphyllos, respectively. It was also the main constituent of the bract oil of the latter (25.8%). Hexadecanoic acid, 2-phenethyl benzoate, beta-ionone, geranyl acetone, farnesyl acetone and hexahydrofarnesyl acetone were characterized as the main oxygenated constituents.
