Inhibition of viral replication in PrV-infected Vero cells after treatment with D. grandiflora leaf extract. a Plates show reduction in plaque numbers in extract-treated PrV-infected cells; a) Negative control, untreated, without plaque formation, b) Positive control, PrV-treated only. The number of plaque decreased with increase in extract concentration. b Quantification of plague inhibition by D. grandiflora leaf extract by difference solvents on PrV replication. a,b indicate significant difference between individual extracts in each concentration at p < 0.05
