ABSTRACT

In this study,the anti-HBV effects of tea polyphenols (TP) were examined.After cells were exposed to TP for 3,6,9 days,amounts of HBsAg,HBeAg and HBV-DNA released into the supernatant of the cultured HepG2 2.2.15 cells were detected.TP,to some extent,inhibited the secre-tion of HBsAg and strongly suppressed the secretion of HBeAg in a dose-dependent (P<0.01) and time-dependent manner,with 50% maximal inhibitory concentration (IC50) value being 7.34 μg/mL on the 9th day,but the time-dependence was not significant (P=0.051).Expression of HBV-DNA in the supernatant of the cell culture also was significantly decreased in a dose-dependent fashion (P<0.01).The IC50 of TP in inhibiting HBV DNA was 2.54 μg/mL.It concluded that TP possessed potential anti-HBV effects and may be used as a treatment alternative for HBV infection.
