Scavenging activity of the cell wall fraction against DPPH• radicals. The antioxidant potential was measured in the cell wall fractions (WSF – water-soluble fraction, CSF – CDTA-soluble fraction, NSF – Na2CO3-soluble fraction, K1SF – 1 M KOH-soluble fraction and K4SF – 4 M KOH-soluble fraction) for fibres from transgenic flax line B14 (checked black bar) and non-transgenic control flax Nike (black bar) and compared with the values for commercially available citrus pectin with various ME values (20-33%, 55-70%, 85%) and standard citrus pectin at a concentration of 5 mg/ml (white bars). Analyses were performed as described in the Methods section. Data represents the mean values ± SD from three independent experiments. The significance of the differences between the means was determined using Student’s t test (* - P < 0.05).
