An effective and profitable processing of a plant residue from wine production represents one of the most significant parts in viticultural research and technology development. Nowadays, only a few parts of viticultural residues are reprocessed, e.g. as an additional agent in cattle and horses feeding or as a food dietary supplements in the form of grape seed flour or extracted wine oil. Plant residues from Vitis vinifera are apparently still rich in bioactive compounds and the interest of agriculture and food-processing companies in their utilization rapidly increases. In our work, antioxidant potential of leaves, stems and grape seeds of Vitis vinifera was evaluated. Antioxidant activity measurements were followed by ABTS method and total phenolic content was performed using Folin-Ciocalteau method. Consequently, content of selected phenolic compounds was analyzed using high-performance liquid chromatography (HPLC) and representation of analytes in different plant parts was discussed. Solid-phase extraction was used as preconcentration and cleaning step. Finally, commercially available food supplements containing viticultural residue were studied and antioxidant effect of individual products was compared.
