Abstract: Sambucus nigra L. (Caprifoliaceae) known as ‘black elder’ is widely used as both food and medicinal plant in Europe. Elderflowers are consumed as herbal tea and its gargle has benefits in respiratory tract illnesses such as cough, influenza, inflammation in throat. In this study, we aimed to show the compositions of the volatile compounds-rich in extract and the essential oil of the elderflowers cultivated in Kütahya, Turkey. HS-SPME (Headspace-Solid Phase MicroExtraction) technique was employed to trap volatile compounds in the hexane extract of dried elderflowers. The volatile compounds in the essential oil from elderflowers isolated by hydrodistillation were analyzed GC and GC-MS systems, simultaneously. Results for the n-hexane extract: thirty volatile compounds were identified representing 84.4% of the sample. cis-Linalool oxide (27.3%) and 2-hexanone (10.5%) were found to be main compounds of the n-hexane extract. Results for the essential oil: fifteen volatile compounds were identified representing 90.4% of the oil. Heneicosane (18.8%), tricosane (17.3%), nonadecane (13%) and pentacosane (10.3%) were the major compounds of the oil.
