[Type text] Groups 2 to 7 were given 25, 50, and 100 mg/kg of test compounds, while group 8 was given the positive control (5 mg/kg of chloroquine). All treatments were given intraperitoneally for four days consecutively. On the fifth day, blood was obtained from the tail vein of the treated mice from all groups. A thin film was made by smearing the blood samples on microscopic slides. The slides were fixed in absolute methanol and stained with 3% Giemsa solution at pH 7.2. Average parasitemia was calculated from six different fields. The percentage average suppression of the parasite by the compounds relative to the negative control was calculated for each group using the
