SEM microphotographs showing the viability of cells in Grapefruit oil (A) and (B) Orange oil (C) and (D) at different time intervals at 24 h and 72 h. Figure (B) shows that at conc 1000, cells were damaged due to shrinkage, round cells floating in the medium, and the presence of cell debris, which is specific for cytotoxicity, and cell death. Figure (D) shows that at conc 1000, There were significant changes in cell morphology such as the area of necrosis and the presence of some cell debris. (C) 24 h, (D) 72 h.
