Figure 2

Cytotoxic activity of tuber extracts from potato cultivars in human neuroblastoma SH-SY5Y cells. Different concentrations (μg CGA equivalents/mL) of skin (white bars) or flesh (grey bars) extracts from Moradita, Waicha, Santa María, and Summerside were studied. Positive control with commercial 5-CGA was added (black bars). Values are presented as the mean ± SD of at least three independent experiments with three technical replicates each.
