Abstrakt: Essential oils of Sambucus nigra were obtained by hydrodistillation and analyzed using the GC-MS technique, which led to the identification and quantification of 66 components from the leaves and 74 components from the flowers, accounting for 94.0 and 96.4% of the total components, respectively. The main class of compounds present in the leaves were fatty acids and their derivatives: methyl linoleate, palmitic acid, hydrocarbon tritetracontane, and an aromatic compound benzoic aldehyde. In the flowers there were hydrocarbons: tritetracontane and n-hexatriacontane, fatty acids and their derivatives: palmitic acid and linoleic acid, and alcohols: 2-methyl-3,15-octadecadienol and 2-hexyl-1-octanol. Among the dominant components of the essential oil of S. nigra flowers, there were also monoterpenes such as rose oxide, epoxylinalol, while the essential oil of the leaves contained a few compounds of monoterpenes in small amounts such as β-pinene and α-pinene. Antioxidant activity of the obtained essential oils was determined by the FRAP and DPPH assay techniques. [ABSTRACT FROM AUTHOR]
