Antiviral Activities of Mulberry (Morus alba) Juice and Seed against Influenza Viruses

Figure 4

Antiviral activities of MAJ and MAS against BR59, KR01, BR10, and FL04 in posttreatment. After virus absorption to cells, the inocula were aspirated; then the cells were incubated with (a) MAJ and (b) MAS for 1 h. After incubation, the cells were washed and overlaid with agarose at 37°C for 72 h. Nontreated influenza virus (IV) and oseltamivir (10 μM) were used as negative and positive controls, respectively. All measurements were performed in triplicate. Within each treatment, an asterisk denotes a significant decrease in the plaque-forming unit (PFU) (log₁₀PFU/mL) to nontreated influenza virus group (P < 0.05).
