    Content of polyphenolic antioxidants and phenolcarboxylic acids in selected organs of yacon [Smallanthus sonchifolius (Poepp. et Endl.) H. Robinson]

  • Original language description

    Yacon [Smallanthus sonchifolius (Poepp. et Endl.) H. Robinson], a native Andean plant cultivated for its tubers and medicinal infusions from leaves, is very rich in phenolic components with strong antioxidant activities. The major phenolic components arechlorogenic acid, caffeic acid and ferulic acid, present both in the form of their esters and the free form. Total polyphenolics were estimated spectrophotometrically with Folin-Ciocalteau´s phenolic reagent in four parts of plant: tubers, rhizomes, stems and leaves. Rhizomes and leaves were observed to be the richest sources of polyphenolic antioxidants (42 200 and 13 700 mg.kg-1 DM, respectively). Polyphenol contents in different parts decreased in order rhizomes > leaves > stems > tubers. These results could evaluate the yacon tubers as a rich source of phenolic antioxidants in human nutrition as well as leaves as an active component in dietary supplements for the prevention of chronic diseases. Major phenolic acids determined using
