The animals were grouped(n¼4 for each
group) and about50 μL of blood were collected from the or bital
plexus using microhematocrit capillary tubes. Before collecting
blood, the tubes were filled with 20 μL ofPSS; Bothrops jararacussu
or Bothrops jararaca crude venoms(1 μg/mL); and venom preincubated for 30min with Combretum leprosum extract(1 and
10 μg/mL) or arjunolic acid(1 and 10 μg/mL). The clotting time was evaluated and compared among the different groups.
