The results showed that plumbagin treated HepG2 cell density was decreased. The apoptotic morphologies were also observed in HepG2 cells after plumbagin treatment. Nucleus staining, RT-PCR and comet assay were applied to study apoptotic morphologies in HepG2 cells. Acridine Orange staining results demonstrated that fragmented HepG2 nucleus by plumbagin was one of the important proves for its  apoptotic induced characteristics. <em>Bax</em> transcript expression was increased in plumbagin treated HepG2 cells. However, there was no difference of bcl-2 transcripts expression between plumbagin treated HepG2 and control, suggesting that plumbagin induced a change in <em>bax</em> and <em>bcl-2</em> transcripts expression of HepG2. Comet assay was applied to measure genomic DNA fragmentation in HepG2 cells. Fragmented DNA percentage in comet tail and comet tail length were increased in HepG2 treating with higher plumbagin concentrations. In conclusion, plumbagin showed apoptotic induced activitiy through morphological changes  in HepG2 cells.}, number={2}, journal={Academia Journal of Biology}, author={Thach, Bui Dinh and Long, Le Thanh and Quynh Chi, Ho Nguyen and Duy, Nguyen Khac and Chung, Doan Chinh and Si, Do Minh and Ho, Nguyen Huu and Suong, Ngo Ke and Son, Hoang Nghia}, year={2014}, month={Oct.}, pages={247–252} }
