Efficacy of spike-ACE2 binding inhibition by the tested extracts. The SARS-CoV-2 S protein RBD coated plate was incubated with plant extracts and biotinylated human ACE2 for 1 h. Thereafter, the plate was washed thoroughly and incubated with streptavidin-HRP followed by colorimetric detection using a multiplate reader from Tecan (Germany). Bars are means + SD of at least three independent experiments. and . Significance of difference was calculated relative to the respective solvent control by one-way ANOVA.
