The activities of ethanol and n-hexane extracts of T. camphoratus and the eight separated fractions from n-hexane extract on the growth inhibition of CL1-0 lung cancer cells. a The cell viabilities of CL1-0 cells were measured after treatment with the ethanol or n-hexane extract of T. camphoratus for 72 h. b Eight fractions (HS1–HS8) were separated from the n-hexane extract by silica gel chromatography according to their polarities displayed in thin-layer chromatography. c The cell viabilities of CL1-0 cells were measured after treatment with n-hexane extract (H) or the separated fraction (HS1–HS8) at dose of 50 μg/mL as indicated for 72 h. Cell viability data (mean ± SE) are expressed as a percentage compared to the control and analyzed as described in “Statistical analysis”. ***p < 0.001 compared to the control group
