(a) Tubers from the four potato cultivars. Shown are entire tubers as well as cross sections and dry polyphenol extracts. Scale bar = 10 cm. (b) Total phenolic acids content and (c) DPPH radical scavenging activity, in skin (white bars) and flesh (grey bars) extracts. Positive control with commercial 5-CGA (0.5 μg) was added (black bars). Values are presented as the mean ± SD of four independent experiments with at least three technical replicates each.
