The effect of the flavonoids on L6 cells viability. MTT assay were conducted at various concentrations (0, 30, 60, 90, 120 and 150 μ g/mL) in the absence or presence of lipopolysaccharide (1 μ g/mL) (A). The morphological changes L6 cells were visualized by optical microscopy (×400) (B). Results are expressed as the mean ± SD of three independent experiments.
