Dose dependent inhibition of protease activity of N. naja venom by L. aspera methanolic extract. 50 μg of N. naja venom was pre-incubated with various concentrations of the plant extract (w/w) for 1 h at 37 °C. The protease activity was assyed by plate method. Venom protease activity in absence of plant extract was considered as 0% inhibition. Values represent the mean ± S.D of replicates.
