Figure 1

The effect of ethanol extract of Saussurea lappa (ESL) on the viability of MCF-7 cells and MDA-MB-231 cells. To test the cytotoxicity of ESL, MCF-7 (A) and MDA-MB-231 (B) cells were cultured in 96-well plates until 70% confluence and treated with various concentrations (0, 1, 2, 5, 10, and 30 μg/mL) of ESL for 24 h. An MTT assay was used to assess the viability of the cells, where the optical density value of an untreated control was regarded as 100% viability. Data represent the mean ± SE of three independent experiments.
