Abstract

The purpose of this paper is to determine the polyphenol content, antioxidative potential and antiproliferative activity of Swiss chard from Montenegro, grown under different irrigation and fertilization regimes.Design/methodology/approachSwiss chard was grown in the open field (Lješkopolje, Montenegro) where it was subjected to different fertilization and irrigation regimes. Chard samples were analyzed for previously identified polyphenols and for antioxidant parameters. Additionally, in order to complete the biological activities, chard extracts were tested for antiproliferative activity against MFC-7 and HT-29 tumor cell lines.FindingsThe polyphenols identified in Swiss chard were flavonoids: vitexin-2?-O-xyloside, vitexin-6?-O-acetyl-2?-O-xyloside, vitexin-6?-O-malonyl-2?-O-xyloside and isorhamnetin-3,7-diglucoside. In the antioxidant tests, DPPH (2,2-diphenyl-1-picrylhydrazyl), and ABTS (2,2'-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid)), chard extract had values of 7.00 and 8.50 (mean values) µmol Trolox (6-hydroxy-2,5,7,8-tetramethylchroman-2-carboxylic acid) equ/d.w., respectively.
