| description | Breast cancer is among the most commonly diagnosed cancer and the leading cause of cancer-related death among women
globally. Malaysia is a country that is rich in medicinal plant species. Hence, this research aims to explore the secondary
metabolites, antioxidant, and antiproliferative activities of Dioscorea bulbifera leaf collected from Endau Rompin, Johor, Malaysia.
Antioxidant activity was assessed using 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing antioxidant power (FRAP), and
2,2′-azino-bis-3-ethylbenzthiazoline-6-sulphonic acid (ABTS) assays, while the cytotoxicity of D. bulbifera on MDA-MB-231 and
MCF-7 breast cancer cell lines was tested using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay. Cell
cycle analysis and apoptosis were assessed using flow cytometry analysis. Phytochemical profiling was conducted using gas
chromatography-mass spectrometry (GC-MS). Results showed that methanol extract had the highest antioxidant activity in
DPPH, FRAP, and ABTS assays, followed by ethyl acetate and hexane extracts. D. bulbifera tested against MDA-MB-231 and
MCF-7 cell lines showed a pronounced cytotoxic effect with IC50 values of 8.96 μg/mL, 6.88 μg/mL, and 3.27 μg/mL in MCF-7 and
14.29 μg/mL, 11.86 μg/mL, and 7.23 μg/mL in MDA-MB-231, respectively. Cell cycle analysis also indicated that D. bulbifera
prompted apoptosis at various stages, and a significant decrease in viable cells was detected within 24 h and substantially improved
after 48 h and 72 h of treatment. Phytochemical profiling of methanol extract revealed the presence of 39 metabolites such as acetic
acid, n-hexadecanoic acid, acetin, hexadecanoate, 7-tetradecenal, phytol, octadecanoic acid, cholesterol, palmitic acid, and
linolenate. Hence, these findings concluded that D. bulbifera extract has promising anticancer and natural antioxidant agents.
However, further study is needed to isolate the bioactive compounds and validate the effectiveness of this extract in the In in
vivo model. |
