Fig. 1From: In vitro antimalarial activity evaluation of two ethnomedicinal plants against chloroquine sensitive and resistant strains of Plasmodium falciparumCalculation of IC50 values by non-linear regression analysis (GraphPad Prism) using nine different concentrations with two-fold serial dilution. For the test extracts the dilution was made from 50 μg/ml to 0.195 μg/ml whereas for the standard drug the dilution was made from 5 μg/ml to 0.019 μg/ml. The experiment was performed in triplicates and each value is the mean ± SD of three replicatesBack to article page
