Viability of HepG2 cells assessed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) reduction and lactate dehydrogenase (LDH) leakage assays. Cells were treated with each extract for 24, 48 and 72 h. Values show mean ± SEM of six independent assays performed in triplicate compared to the respective control (** p < 0.01 and ^# p < 0.0001).
