Figure 2: Cytotoxic activity of the chloroform fraction and the crude hydroethanolic extract of S. filiforme in A549 cells. Cell viability of A549 cells after 48 h of exposure with different concentrations of Cisplatin, the crude extract and the chloroform fraction of S. filiforme was evaluated by MTT reduction assays. The Figure shows the concentration-response curve for the cytotoxicity of the three products from 0.01 to 1000 μg/ml in comparison to untreated control cells and cells treated with dimethyl sulfoxide 1% (vehicle control). The values are shown as mean percentages of control from three independent experiments. bars, standard deviation. *P < 0.05 and ***P < 0.001 versus control (untreated cells)
