Trypanocidal Activity of Smallanthus sonchifolius: Identification of Active Sesquiterpene Lactones by Bioassay-Guided Fractionation

Figure 7

Cytotoxicity of enhydrin, uvedalin, and polymatin B on Vero cells. Cultures were kept for 24 h in the presence of different concentrations (1 to 50 μg/mL) of the STLs. Cell viability was determined by the MTT method and was expressed as the ratio between viable cells in the presence and absence of the compound multiplied by 100. Bars represent the mean ± SEM of three experiments carried out in duplicate.
