Fig. 6. Effect of Combretum leprosum extract and arjunolic acid on Bothrops jararaca and Bothrops jararacussu venoms phospholipase A2 activities. Data show the PLA2 activity
of each venom alone(10 μg/mL) or preincubated with in creasing concentrations of Combretum leprosum extract(Bothrops jararaca panel A, Bothrops jararacussu panel B).
In panels C and D,PLA2 activities of 10 μg/mL of each venom or both ropstoxin II (BthTx-II)were considered as 100%.Panels show the inhibitory effects of increasing
concentrations of arjunolic acid.Data report mean 7 SEM (n¼5).
