CELL CYCLE ARREST ACTIVITY OF LITSEA CUBEBA LOUR: HEARTWOOD AND FRUIT EXTRACTS AGAINST T47D BREAST CANCER CELLS

Objective: This study was carried out to investigate cell cycle arrest activity toward T47D cells of Litsea cubeba heartwoods and fruits extract.Methods: Dry extracts were prepared from dry-grounded heartwoods and fruits by cold maceration using n-hexane, ethylacetate, and ethanol solvent. Cytotoxic activity were measured by [3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyl tetrazolium bromide] methods and interpreted with inhibitory concentration 50% (IC50) value. Cell cycle arrest was investigated by flowcytometry method.Results: IC50 values for each n-hexane, ethylacetate, and ethanol of L. cubeba heartwoods and fruits were 76.34±2.61; 67.52±2.45; 71.23±2.37; 75.59±3.24; 162.58±15.08; 63.70±2.67 μg/mL, respectively. Cell cycle arrest for ethylacetate extract of heartwoods and fruits were accumulated in G0/G1 phase (56.70% and 65.56%).Conclusion: These results suggest that L. cubeba heartwoods and fruits has cell cycle arrest activity.
