2007 m. Nr. 1 Influence of urban environment on chemical composition of essential oil of Tilia cordata
The composition of essential oils of Tilia cordata blossom collected from ecologically clean localities and urban environment (Vilnius city) was analyzed by GC-MS. The main differences in the essential oils were revealed by the analysis of oxygenated compounds (monoterpenes, sesquiterpenes, aliphatics and others). The essential oils of linden blossom from the clean localities contained 47.3–55.0% of oxygenated constituents, while the blossom oils from trees growing on the tile-covered pavements contained only 20.6–27.7% of these compounds. The major constituents determined in linden blossom oils were 3-p-menthene, nonanal, nonanoic acid, a-cadinene, hexahydrofarnesyl acetone, kaurene, aliphatic hydrocarbons (C20H42 – C24H50). The identified compounds (169 out of 250) made up 73.4–97.7% of the oils. Keywords: Tilia cordata Mill., Tiliaceae, composition of essential oils, urban environment |
