Cellular viability under different concentrations of peel and whole fruit extracts. HTR-8/SVneo cells 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 chloroquine diphosphate (positive control) (A), whole fruit extract (STWFE) (B) and peel extract (STPE) (C). Vero E6 cells were treated with STFWE (D) and STFE (E) at the same concentrations. All different concentrations of whole fruit (STWE) aqueous extract have not altered trophoblast cell viability, the same occurring for both STFWE and STFE treatments in Vero E6 cells. The bar graphs represent the mean values ± S.E.M.; n = 3 in triplicate. *, p < 0.05.
