Relative viability of the CHO-K1 cells (resazurin assay) after 1 day of incubation with lilial at seven concentrations without or with metabolic activation using the S9 mix. The final concentration of DMSO was 0.1%, this vehicle control (VC) was taken as 100% viability. 0.25% Tween-20 served as a positive control (PC). Error bars represents for the standard error deviation of six replicates (wells). Statistically evaluated using t-test (*indicates statistically significant difference from corresponding VC at p < 0.05, **p < 0.005, ***p < 0.0005).
