Objective : To study the clerodendrum flavonoids on cultured in vitro proliferation of human hepatoma HepG2 cells. Methods : traditional Chinese medicine active ingredients of clerodendron clerodendrum flavonoids, re- spectively for using different concentrations of HepG2 cells and establishment of the blank control and the positive control group, by cell morphology and MTT assay for detection of clerodendrum effects of flavonoids on the growth of HepG2 cells. Results : concentrations of total flavonoids from clerodendron 0. 025,0.25,2. 5,25...
