Placental tissue explants viability under different concentrations of peel and whole fruit extracts. Placental explants were treated with DMEM/F12 solution (Control), and with 0.01 μg mL⁻¹, 0.1 μg mL⁻¹, 1 μg mL⁻¹, 10 μg mL⁻¹ and 100 μg mL^-1 of whole fruit extract (STWFE) (B) and peel extract (STPE) (C). None of the different concentrations of the studied extracts or chloroquine diphosphate reduced placental tissue explants viability. The bar graphs represent the mean values ± S.E.M.; n = 3, in triplicate.
