Plaque reduction assay of Vero cells infected with PrV pre-treated with D. grandiflora leaf extracts. (A) Plates show reduction in plaque formation; a) Negative control, not treated. b) Positive control treated with PrV only. Greater reduction in plague formation with increase in extract concentration. No plaque formation at 250 and 500 μg/mL extract. (B) Quantification of plague reduction. a,b,c indicate significant difference between individual extracts in each concentration at p < 0.05
