Abstract:Objective To study the anti-HBV action of total flavonoids extracted from Alternanthera philoxeroides in vitro. Methods HepG2.2.15 cells were inoculated into the cell culture plates and then randomly divided into negative control group, experimental group and positive control group. The negative control group was treated with 100 mL/L DMSO, the experimental groups were treated with 800, 400, 200 and 100 mg/L total flavonoids extracted from Alternanthera philoxeroides. In the positive control groups, lamivudine was added at the concentration of 800, 400, 200 and 100 mg/L. Cell culture and optical density assay were used to study the effects of total flavonoids from Alternanthera philoxeroides on the expression of HBsAg and HBeAg in HepG2.2.15 cell line. Results The inhibit the expression of HBsAg in HepG2.2.15 cells in each experimental group was obviously higher, compared with the negative group, the difference was statistically significant (P < 0.01) and compared with the positive control group, the difference was statistically significant (P < 0.05), the inhibition rate of HBsAg in the experimental group was positively correlated with the dose of the drug. Each dose of the experimental groups had obvious inhibitory effects on the expressions of HBeAg in HepG2.2.15 cells, compared with the negative control group, the difference was statistically significant (P < 0.01) compared with and positive control group, the difference was statistically significant (P < 0.05), the inhibition rate of HBeAg in the experimental group was positively correlated with the dose of the drug. Conclusion Total flavonoids extracted from Alternanthera philoxeroides has obvious inhibitory effects on the expressions of HBsAg and HBeAg in HepG2. 2. 15 cells. Total flavonoids extracted from Alternanthera philoxeroides has strong anti-HBV action in vitro.
