RESUMO
The present study aimed to investigate the potential inhibitory activities of various Terminalia brownie extracts against the proliferation of different cancer cell lines. Fractionation was carried out through the process of liquid-liquid extraction produced four fraction types using polarity-enhancing solvents such as, n-hexane, chloroform, ethyl acetate, and water. All extracts have been tested for their cytotoxicity against cancer cell lines using SRB assay and their inhibitory activity on cell cycle phases using flow cytometry. The chloroform extract exhibited a cytotoxic effect against all three types of cancer cell lines and especially the HepG2 cells at 100-µg concentration. Moreover, the most prominent plant extracts of chloroform, acetyl acetate, and hexane showed significant induction of cell death during the S phase cell cycle. The findings of this study suggest that compounds in the Terminalia brownie plant used in traditional Saudi medicine may have the potential to suppress the growth of cancer cell lines.
