Virgin coconut oil (VCO) is rich with antioxidant and exhibit anti-cancerous properties. The ability of VCO to inhibit the
growth of lung cancer cells by inducing apoptosis has yet been reported. NCI-H1299 (a non-small cancer cell) and A549
(adenocarcinomic human alveolar basal epithelial cells) were incubated in media containing various concentration of VCO for
1, 3, 5 and 8 days. The morphology of the cells were observed and viable cells was counted following treatments. Apoptotic
features were observed on cell membrane treated with VCO, indicated by the appeareance of giant bubbles and massive
cytoplasmic vacuoles. The effect of VCO treatment also was observed in cell proliferation assay in which high doses of VCO
greatly inhibit the cell proliferation activity as early as 1 day post treatment and suggest it was a time-dependent. This study
shown that VCO can induce apoptosis in cancer cell lines which responsible for the anti-cancer properties.
