The composition of essential oils from Tilia L. Species growing in Turkey

Abstract

Essential oil 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.M). Kaur-l6-ene (29.3% and 41.9%) was the major constituent in the leaf oils of T. rubra and Tplatyphyllos, respectively. It was also the main constituent of the bract oil of the latter (25.8%). Hexadecanoic acid, 2-phenethyl benzoate, ß-ionone, geranyl acetone, farnesyl acetone and hexahydrofarnesyl acetone were characterized as the main oxygenated constituents
