Apoptotic screening using flow cytometry of the tested formulas against lung cancer A549 versus normal WI-38 cells. A apoptotic diagrams of A549 cells, B apoptotic diagrams of WI-38 cells. C Cells did not stain with dyes and named un-apoptotic cells, D cells stained with Annexin V and shifted to early apoptosis, E cells stained with propidium iodide (PI) and shifted to necrosis, F cells stained with Annexin V and PI and shifted to late apoptosis (n = 3)
