Triterpenoid Saponins Isolated from Platycodon grandiflorum Inhibit Hepatitis C Virus Replication

Figure 5

Inhibition of HCV protein expression by triterpenoid saponins in HCV replicon cells. HCV replicon cells were treated with the indicated amounts of triterpenoid saponins. Con indicates a vehicle (DMSO). Three days after treatments, cell lysates were immunoblotted with an anti-NS5A antibody. Actin protein was used as a loading control.
