摘要
Chlorogenic acid and its related compounds are abundant plant polyphenols that have a diverse antiviral activity. In this study, HepG2.2.15 cells and duck hepatitis B virus infection model were used as in vitro and in vivo models to evaluate their anti-HBV activity. In the cell model, all the three compounds inhibited HBV-DNA replication as well as HBsAg production. Chlorogenic acid and caffeic acid also reduced serum DHBV level in DHBV-infected duckling model. Moreover, the anti-HBV activity of crude extracts of coffee beans, which have a high content of chlorogenic acid, was studied. Both the extracts of regular coffee and that of decaffeinated coffee showed inhibitory effect on HBV replication.
