Figure 6.
Effect of monoterpene combinations on NSCLC cellular viability in vitro. A549 cells were treated with different concentrations of monoterpenes alone or in combination for 48 h. Cellular viability was assessed using CellTiter-Glo Luminescent Assay as described in the materials and methods. Experiment was repeated at least three times. Columns represent means, and bars represent S.E.M. **** p < 0.0001. ns—non-significant. Black stars indicate significance in comparison to the control; red stars indicate significance between groups.
