The cytotoxic activity of Cratalariae sessiliflorae on cultured NIH 3T3 fibroblasts and human oral epithelioid carcinoma cells (KB) were evaluated by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazoliumbromide (MTT) colorimetric method These fractions of methanol extract of Cratalariae sessiliflorae showed inhibitory effect in vitro in the milligram range against KB cell lines. In general, the antitumor activities of these fractions were does-dependent over the milligram range. The comparison of IC50 values of these fractions in tumor cell lines showed that their susceptibility to these fractions decrease in the following order: Fr. 4> Fr. 6> Fr. 10> Fr. 2> Fr. 11> Fr. 3> Fr. 8> Fr. 7> Fr. 9> Fr. 1> Fr. 5 by the MTT assay. These fractions were tested for their cytotoxic effects on NIH 3T3 fibroblasts using MTT assay. They exhibited potent cytotoxic activities in vitro in the milligram range against NIH 3T3 fibroblasts. In general, the cytotoxic activities of these fractions were does-dependent over the milligram range. The comparison of CD50 values of these fractions in NIH 313 fibroblasts shows that their susceptibility to these fractions in decrease the following order: Fr. 10> Fr. 9> Fr. 2 = Fr. 4> Fr. 8> Fr. 11> Fr. 1 = Fr. 7> Fr. 3> Fr. 5 = Fr. 6 by the MTT assay. These results suggests that fraction 5 has the most growth - inhibitory activity against KB cell lines.
