Abstract: The volatile composition of propolis and poplar tree gum was analyzed by headspace solid phase micro-extraction followed by GC-MS coupled to olfactometry. A total of 48 aroma-active compounds were identified, including esters, aldehydes, alcohols, ketones and acids. In propolis, there were many compounds responsible for the floral and fruity aroma and providing it with delicate and mellow aroma characteristics.

Key words: propolis, poplar tree gum, aroma-active components
