A graph of flow cytometric analysis shows the percentage of apoptotic cells after treatment with MBS extract for 24 h in comparison with untreated cells (Negative control). The extract’s concentrations represent 2-fold serial dilutions (concentration > IC50 > concentration). A) Apoptotic % of HeLa cells. B) Apoptotic % HepG2 cells. The increase in the percentage of the apoptotic cells was dose dependent.
