Volatile Constituents from the Leaves of Young and Old Ailanthus altissima (Mill.) Swingle Tree

The chemical composition of volatile compounds from the tree of heaven leaves (Ailanthus altissima (Mill.) Swingle) was analysed, for the first time, by gas chromatography-mass spectrometry (GC-MS). The volatiles were isolated from fresh as well as from dried leaves of young and old trees. Forty-nine compounds were identified, representing 88.5&#8211 ; ; 96.3% of total volatiles. The main constituents were aliphatic C6-compounds (alcohols, aldehydes, acids, esters) 30.8&#8211 ; ; 59.7%, sesquiterpene compounds, especially hydrocarbons (beta-caryophyllene, alpha-humulene, gama- and delta-cadinene, calarene) 11.3&#8211 ; ; 57.4%, oxygenated monoterpenes (linalool, geraniol, alpha-terpineol) 3.6&#8211 ; ; 9.4% and other compounds 4.5&#8211 ; ; 12.0%. The stage of plant development and the air-drying of plant material have a strong influence on the qualitative and quantitative composition of ailanthus volatile compounds.
