[Objective] The aim was to build up a set of efficient and rapid models for laboratory to screen anti-hepatocellular carcinoma active substance in vitro. [ Method] By using MTT method, the activities of anti-hepatocellular carcinoma SMMC-7721 in vitro from Cymbopogon distans, Lobelia chinensis, Buddleja offlcinalis, Glycyrrhiza uralensis, Sanguisorba officinalis, Bupleurum chinense, Apium graveolen and Curuma zedoaria were tested. The growth curve of hepatoma cell was described, and the growth status in different periods were observed by inverted microscope. [ Result] Cells induced by active substance would be condensing, clear brim, which have significant differences from normal SMMC- 7721 cells. The results suggested that ESCG, ESCC, ESCB could inhibit proliferation of SMMC-7721 cells at the concentration of 1.0 -1.5 mg/ml, and the inhibition rate were 51.6%, 48.5%, 52.9% respectively. With the increasing of concentration, the inhibition strengthened. [ Conclusion] MTT method could be used as a basic model for screening important anti-hepatoma.
