The anti-proliferating effects of some plants on hepatoma cell lines were studied by the 3-[4,5-dim-ethylthiazol-2yl]-2,5-diphenyl-tetrazolium bromide (MTT assay), to investigate the anticancer effect with some plants around here. As the result, we saw that the anti-prolferating effect to the plants. Among the plants, Equisetum arvense L. and Lactuca dentata Makino. var, flaviflora Makino of them relatively showed a good ant-proliferating effect. Capsicum annuum L. var. angulosum Mill (Leaf) was the best among them. We also examined morphological changes on the hepatoma cells in this process. In case of Capxicum annuum L. var. angulosum Mill, the tells become vague after 2 days, and then destroyed faster than others. We can fee also the condensated chromosome on the treated cells with Capxicum annuum L. var. angulosum Mill. And we also observed condensation through using a fluorescent microscope by PI staining, and observed DNA fragmentation.
