Objecgtive : The aim of present study was to investigate inhibition effect of Whakijogyung-Tang(WJT) on the tumor cell lines. This study estimated the cytotoxicity of WJT about viability of S-180 and NlH3T3. Methods : The cytotoxicity of WJT about viability of cells were tested using a colorimetric tetrazoliun assay(MTT assay) Results and Conclusion : 1. Water extract of WJT had $IC_{50}$ of 863 ${\mu}g/ml$ in S-180 cell lines, but cytotoxicity of NIH3T3 was not significant difference compare with S-180. 2. n-Hexane fraction of WJT had similar cytotoxicity between S-180 and NIH3T3, but that could not have $IC_{50}$ in S-180 cell lines. 3. Ethyl acetate fraction of WJT had low degree cytotoxicity both S-180 and NIH3T3 cell lines. 4. Significantly, Butanol fraction of WJT had differenct citotoxicity between S-180 and NIH3T3. 5. $H_2O_2$ fraction of WJT had no cytotoxicity both S-180 and NIH3T3.
