Název v původním jazyce

Content of polyphenolic antioxidants and phenolic acids in selected parts of yacon (Smallanthus sonchifolius (Poepp. et Endl.) H. Robinson)

Popis výsledku v původním jazyce

Yacon [Smallanthus sonchifolius (Poepp. et Endl.) H. Robinson], a native Andean plant cultivated for its tuberous roots and medicinal infusions from leaves, is very rich in phenolic components with strong antioxidant activities. The major phenolic components are chlorogenic acid and caffeic acid, present both in the form of their esters and in the free form. Total polyphenolics were estimated spectrophotometrically with Folin-Ciocalteau´s phenolic reagent in four parts of plant: tuberous roots, rhizomes, stems and leaves from the harvests in the years 2002 and 2003. Rhizomes and leaves were observed to be the richest sources of polyphenolic antioxidants (31 600 and 14 300 mg.kg-1 DM, respectively). Polyphenol contents in different parts decreased in order rhizomes > leaves > stems ł tuberous roots. As compared with potato tuberous roots, the yacon tuberous roots are 3 ? 10 times richer in polyphenolic antioxidants. These results could evaluate the yacon tuberous roots as a rich source
