AIM: To study the anti-tumor effect of resveratrol alone and the synergistic effects of resveratrol with 5-FU on the growth of H22 cells line in vitro. METHODS: The number of cells was measured by MTT method the morphological changes of H22 cells were investigated under microscopy and electron microscopy examination. RESULTS: Resveratrol inhibited the growth of hepatoma cells line H22 in a dose- and time-dependent manner, IC50 of the resveratrol on H22 cells was 6.57mg x L(-1),The synergistic anti-tumor effects of resveratrol with 5-FU increased to a greater extent than for H22 cells treated with 5-FU alone (70.2% vs 28.4%) P<0.05 .Under microscope and electron microscope, characteristics of apoptosis such as typical apoptotic bodies were commonly found in tumor cells in the drug-treated groups. CONCLUSION: Resveratrol can suppresses the growth of H22 cells in vitro,its anti-tumor activity may occur through the induction of apoptosis.
