Figure 5. Cytotoxic effects of ZnONPs and extracts on HepG2 cells upon 24 hour treatment with 200 µg/ml concentration. Untreated cells, DMSO (solvent) and Doxorubicin (34 µM) were included as controls. Microscopic images of HepG2 cells (treated and untreated). Magnification = 200X, Scale = 100 µm. (A) Callus extracts (CE). (B) Callus derived ZnONPs (C-ZnONPs). (C) Untreated HepG2 cells. (D) Whole plant extracts (WPE). (E) Whole plant derived ZnONPs (W-ZnONPs). (F) DMSO 1% (negative control). (G) Doxorubicin 34 µM (positive control).
