Dose-dependent inhibition of HCV infection by ethanol extracts of TSL, MLL, MMS and FFL. The HCV J6/JFH1-P47 (A) and -P1 strains (B) were mixed with serial dilutions of the plant extracts and inoculated to Huh 7.5 cells at an MOI of 0.5 and 0.05, respectively. After virus adsorption, the cells were cultured with the same concentrations of plant extracts for 46 hours. The culture supernatants were harvested and titrated for the virus infectivity. Percent inhibitions of HCV infectivity by the plant extracts at the concentrations of 0.1 to 100 μg/ml are shown. Data represent means ± SEM of data from two independent experiments.
