Effect of EO from A. lanatum on cell viability. EO inhibited cell growth and cell proliferation in HepG2 liver cancer cells and NIH-3T3 normal murine fibroblast cells: (A) HepG2 and NIH-3T3 cell lines were supplemented with EO (0–100 μg/mL) or a vehicle control (0.1% DMSO) for 48 h periods, and cell viability was assessed by MTT assay, and (B) HepG2 and NIH-3T3 cells were supplemented with EO (0–100 μg/mL) for 24 h, and cell morphology was examined beneath a phase-contrast microscope. The data are shown as the mean ± SD of triplicate measurements; * p < 0.05 when evaluated with respect to control cells.
