Cytotoxicity of the C. europaea extracts for K562, HL60, and Huh-7 cell lines. (A): Hydroethanolic extract; (B): Polyphenolic extract; (C): Flavonoids extract; (D): Saponins extract, after 24, 48, and 72 h of treatment with different concentrations of the C. europaea extracts. The wavelength of 570 nm was used to measure the absorbance. The results are expressed as mean ± SD of three experiments. The error bars represent the standard deviation of cell viability at each concentration tested. Cell viability was assessed through MTT assay. Values significantly different compared to negative control * p < 0.05; **: p < 0.01; *** p < 0.001; **** p < 0.0001.
