Cell viability following treatment with HCAs. Cell viability of (A) B164A5 mouse melanoma and (B) A375 human melanoma cell lines following treatment with 50 and 100 µg·ml⁻¹ caffeic acid, coumaric acid, ferulic acid and rosmarinic acid. Values are presented as the mean ± standard deviation. All in vitro experiments were carried out on two microplates in quadruplicate for each tested substance, as well as control samples. No statistically significant differences were observed between groups.
