Volatile Constituents and Antimicrobial Activity of Tilia tomentosa Moench and Tilia cordata Miller Oils.

The essential oils of bracts and inflorescences of cultivated Tilia tomentosa and T. cordata from Greece and Romania, respectively, were investigated. Essential oils were obtained by hydrodistilation and analyzed using GC and GC/MS. The oils of from the inflorescences of T. tomentosa and T. cordata were characterized by a high percentage of hydrocarbons (32.3% and 60.4%, respectively) with tricosane being the main component (21.5% and 31.3%). Isocyclocitral (15.3%) and hotrienol (11.5%) were characterized as the main oxygenated monoterpenes of T. tomentosa and T. cordata inflorescences oils, respectively. Linalool (13.1%) and hexahydrofarnesyl acetone (17.7%) were the major constituents in bract oil of T. tomentosa, whereas the bract oil of T. cordata was characterized by the predominance of hydrocarbons (87.4%) with tricosane (32.2%) being the main constituent.
