The aim of the present study was to determine the composition of essential oils (EOs) of different plant parts of A. altissima , growing in Bulgaria. Four samples (flowers, immature samaras, leaves, stem bark) of A. altissima were collected in the period June-July of the 2019 growing season, from Plovdiv, Bulgaria. The EOs were obtained by hydrodistillation with a Clevinger-type apparatus. Gas Chromatography/Mass Spectrometry analysis was applied to determine the volatile compounds. The yield (in fresh material) was 0.5 ml/kg (samaras), 0.27 ml/kg (flowers), 0.23 ml/kg (leaves), and 0.18 ml/kg (bark). There were identified 75 volatiles from the different plant parts. Oxygenated hydrocarbons (mainly fatty acids, their esters) were the best-represented group in samaras, leaves, bark (65.87%; 47.53%; 49.41% respectively). Oleic acid was the major constituent in the three EOs (samaras -34.26%; stem bark -30.21%; leaves -22.94%). In the flower EO, the dominant group was sesquiterpene hydrocarbons (46.48%) with main compounds β-caryophyllene (16.98%) and germacrene D (16.24%). The volatile components in Ailanthus altissima , growing in Bulgaria, have been determined for the first time. Differences in the composition of EOs were found.
