Chemical profile and antioksidant activity of Helianthus tuberosus

Abstract

Helianthus tuberosus L., commonly known as the Jerusalem artichoke, belongs to Helianthus genus and Asteraceae botanical family. Due to its wide range of biological activities, aim of this study was to investigate chemical profile of extracts obtained using different approaches: maceration, percolation, infusion and Soxhlet extraction. Extracts were further investigated regarding heavy metal, saccharides, total phenolics and total flavonoids contents, as well as antioxidant activity using DPPH assay. Obtained results showed presence of all investigated species, as well as significant capability of prepared extract to scavenge DPPH radicals.
