    The burning taste of Capsicum fruits is due to the presence of the chemical group of alkaloid compounds called capsaicinoids, among which capsaicin and dihydrocapsaicin are responsible for 90% of the total pungency. The pepper fruits contain also the small amounts of essential oil, which gives them a distinctive flavor and aroma. The main objective of the present study was to determine the chemical composition of essential oils of the fruits of three hot pepper cultivars: ‘Wulkan’, ‘Padron’ and ‘Trakijska Shipka’. The essential oils were isolated from hot pepper fruits by water-steam distillation and analyzed using gas chromatography-mass spectrometry (GC-MS). Palmitic acid (11.98 and 8.96% in 2010 and 2011, respectively), pentadecanal (6.46 and 13.70%), furfural (4.02 and 1.28%), 1-nonadecene (3.67 and 5.34%), 2-methoxy-4-vinylphenol (3.26 and 1.54%) and linoleic acid (2.23 and 2.16%) were found to be the major constituents of ‘Wulkan’ cultivar volatile oil. In the essential oil of ‘Padron’ cultivar, palmitic acid (8.45 and 12.52%), furfural (6.81 and 3.32%), benzeneacetaldehyde (4.28 and 1.55%), 2-acetylpyrrole (2.31 and 1.48%) and 2-methoxy-4-vinylphenol (2.00 and 3.10%) were the most abundant compounds. Similarly, palmitic acid (10.00 and 11.17%), pentadecanal (9.04 and 11.81%), 1-nonadecene (6.17 and 10.72%), furfural (6.10 and 2.60%) as well as nonadecane (3.99 and 5.19%) and 2-methoxy-4-vinylphenol (2.82 and 1.77%) dominated in the essential oil of ‘Trakijska Shipka’ cultivar.
