on plasma coagulation of
venom. The venom (20 μg/mL) was incubated with algal extracts (100 μg/mL) prepared in n-hexane (group I), dichloromethane (group II), ethyl acetate (group III) or hydroalcoholic solution (group IV), then the mixtures were added to plasma and coagulation was monitored. Control groups consisted of venom incubated with NaCl (C1) or with DMSO (C2). Results are expressed as mean ± SE of two individual experiments (n = 3). *p < 0.05 when compared to C1 or C2.
