Quantification of SARS-CoV-2 inhibition (%) in the full-time entry, entry, and post-entry treatments of 50 µg/ml of Polygala Root ext., Areca ext., Quercus Bark ext., 50 µM of baicalin, and 12.5 µM of glabridin on qRT-PCR at 16 h pi, MOI 0.1. The mean ± SD were calculated from triplicate experiments. *p < 0.05, **p < 0.01, **p < 0.001 between full-time entry, entry, and post-entry treatments after normalization with the virus control
