Fig. 7. A 60% ethanol extract of Echinacea purpurea (EPE) and chicoric acid (CA) exhibit inhibitory activities against viral neuraminidase (NA). The inhibition activity against viral NA is evaluated through an NA assay. Results of the NA assay for H1N1, and influenza B virus (IVB) using 1,000 µg/mL EPE or 189.75 µg/mL CA are shown. Data are presented as mean±SD (n=3). *P<0.05 vs. the virus control group; ****P<0.0001 vs. the virus control group. DMSO, dimethyl sulfoxide.
