Figure 4: Effect of daylily flowers extracts on the cell viability of macrophages. RAW264.7 macrophages were incubated with DFAE (a), EF (b), DFEE (c), WF (d) or EF-1 to EF-6 (e) for 24 h, and the cell viability was analyzed by MTT assay. The data are expressed as the mean ± SD of three separate experiments. *P < 0.05, **P < 0.01 and ***P < 0.001 compared to vehicle-treated cells. |
