Toxicity of extracts from the stems of J. multifida to MDCK cells. H2O, EtOAc, Hex, and CHCl3 extracts from the stems of J. multifida (12.5-100 μg/mL) in DMSO (concentrations of DMSO: 12.5 μg/mL, 0.125%; 25 μg/mL, 0.25%; 50 μg/mL, 0.5%; 100 μg/mL, 1%) were added to the MDCK cells. Cell viabilities were determined via MTT assay after 24 h (n = 6 each) (a), 72 h (n = 6 each) (b), and 96 h (n = 6 each) (c). Data are the mean ± SEM representative of two independent experiments. *p < 0.05; **p < 0.01; ***p < 0.001 in comparison with DMSO
