Abstract
Metabolic profiling of the hexane extract and essential oil of Cordia africana Lam., an economically important agroforestry species, was performed using GC-FID and GC-MS. Cytotoxicity was assessed in MCF-7 cancer cells using sulphorhodamine-B assay. Caspase-8, BcL-2 and Ki-67 levels were evaluated using enzyme-linked immunosorbent assay. Forty-one compounds were identified in the hexane extract, meanwhile, eighty compounds were annotated in the essential oil. n-Decane (9.52%), β-sitosterol (8.13%), undecane (6.32%) and palmitaldehyde (5.50 %) were the major compounds identified in the hexane extract, whereas, β-caryophyllene (32.0%), germacrene D (10.12%) and δ-cadinene (7.20%) predominated in the essential oil. The half maximal inhibitory concentrations (IC50) of the extract and oil were 4.55 µg/mL and 12.90 µg/mL, respectively. Caspase-8 activity increased significantly in hexane extract treated cells. Furthermore, BcL-2 and Ki-67 protein expression levels were significantly decreased. Cordia africana Lam exhibit potent cytotoxicity against breast cancer cell line, most likely through apoptosis regulation.
