Viola tricolor Induces Apoptosis in Cancer Cells and Exhibits Antiangiogenic Activity on Chicken Chorioallantoic Membrane

Figure 3

Effects of Viola tricolor hydroalcoholic (HAE) extract and its ethyl acetate (EtOAc) fractions on proliferation of L929 cells. The cells were treated for 24 h and then percent of viable cells (quantified by MTT assay) was normalized against untreated control cells (0 μg/mL). Data are mean ± SEM of three independent experiments performed in triplicate. versus untreated control cells.
