Figure 3From: Combination of extracts from Aristolochia cymbifera with streptomycin as a potential antibacterial drug Percentage of living MA104 mammalian cells as a function of the concentration of extracts from Aristolochia cymbifera determined by MTT colorimetric assay. Three curves were obtained by non-linear regression to estimate the CC50 values (mg L1). For EHI (▲), EDI (■) and EHE (●), the CC50 values were 19.29, 23.30 and 40.75 mg L-1, respectively.Back to article page
