Inhibitory effect of fraction A during pre-infection, co-infection and post-infection on HSV-1 [A] and HSV-2 [B]. Different concentrations of fraction A [7.8 μg/ml (square), and 14.5 μg/ml (triangle)] were added with the HSV-1 and HSV-2 infected Vero cells at various time period like pre-infection (−1 h), co-infection (0 h) or post-infection (1-24 h). After 3 days of incubation at 37°C, inhibition was evaluated by MTT assay and expressed as the inhibition percentage. Each bar represents the mean ± S.E.M of three independent experiments.
