Dried leaves of Marchantia convoluta are largely used to protect livers,and to treat tumefaction of skins in China. Flavonoids from Marchantia Convoluta (MCF) was one of the mostpotentially effective anti-inflammatory. MCF was studied here for its ability to inhibit the proliferation of 2,2,15 cells(clone cells derived from HepG2 cells that were transected with a plasmid containing HBV, DNA). All concentrations(5,10,20 and 40 :g/ml) of MCF inhibit hepatitis B surface antigen (HbsAg) and hepatitis B E antigen (HbeAg) in thecultured medium released from 2.2.15 cells. Analysis of morphological changes of MCF-treated phase- contrastmicroscope revealed a possible model of action for MCF to inhibit Proliferation of 2.2.15 cells by inducing apoptosis.
