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

Figure 1

Effects of Viola tricolor on proliferation of MCF7 cells. The cells were treated with increasing concentrations of hydroalcoholic (HAE) extract or its water, -butanol, or ethyl acetate (EtOAc) fractions for 24 h. The percent of viable cells was normalized against untreated control cells (0 μg/mL). Data are mean ± SEM of three independent experiments performed in triplicate. and versus untreated control cells.
