Streszczenia
Due to its pharmacological activity,Sambucus nigraL. is excellent potential componentof functional food. The main aim of presented study was the quantitative and qualitative analysis(LC-ESI-MS/MS) of phenolic acids and flavonoids present in extracts obtained from corn snackswith addition of elderberry fruits or flowers. Additionally, antiradical activity of samples wasdetermined. Moreover, the comparison of various extraction methods of polyphenols from thatfunctional food was made. In corn snacks, without additives, nine phenolic compounds were iden-tified. These were protocatechuic, 4-OH-benzoic, caffeic,p-coumaric, salicylic, ferulic acids, rutin,isoquercetin and apigenin-7-glucoside. In the extract fromSambucusflowers and extract fromsnacks containing 20% ofSambucusflowers fifteen polyphenols were found. They were additionallygallic, gentisic, vanillic, sinapic acids, kaempferol-3-rutinoside and astragalin. The radical-scavenging activity of the extracts was determined spectrophotometrically against DPPH(2,2-diphenyl-1-picrylhydrazyl) radical and using thin layer chromatography. The high antiradicalpotential was observed for crude extracts fromSambucusflowers or fruits and for extracts enrichedwith 20%, 10%, 5% ofSambucusflowers. The product with a 20% addition of fruits revealed mod-erate free radical scavenging properties
