Purpose: To determine the chemical components of the essential oil of Elsholtizia dense in Sichuan
Province and evaluate the effect of the oil on human hepatoma cells (SMMC-7721) in vitro.
Methods: The essential oil was extracted using the modified steam-distillation extraction method, and
its chemical components were determined by gas chromatography-mass spectrometry (GC-MS). The
effect of the essential oil on proliferation of SMMC-7721 cells was studied by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) assay, with L02 and HeLa cells serving as control
Results: GC-MS results show that the essential oil of E. dense contains 40 components. Thirty seven
components were identified and accounted for 98.39 % of the essential oil. The two main components
were rosefuran epoxide (53.12 %) and 2-ethyl imidazole (29.8 %). The oil significantly inhibited cell
proliferation in a concentration- and time-dependent manner (p < 0.05). SMMC-7721 cells were more
inhibited than L02 and HeLa cells by the oil, with half maximal inhibitory concentration (IC50) values of
26.23 and 25.46 μg/mL after 8-h and 24-h treatments, respectively.
Conclusion: Out of the 40 chemical components of the essential oil of E. dense, rosefuran epoxide and
2-ethyl imidazole were the most abundant. The oil has a significant anti-tumor effect on SMMC-7721
cells, and thus has a potential to be developed as an anti-liver cancer drug.
