Figure 6: Effect of daylily flowers extracts on IL-6 production in lipopolysaccharide (LPS)-activated macrophages. RAW264.7 macrophages (a and c) or J774A.1 macrophages (b and d) were incubated with daylily flowers aqueous extract, daylily flowers ethanolic extract or vehicle for 0.5 h, followed by stimulation with LPS for 24 h. The IL-6 levels in the supernatants were analyzed by enzyme-linked immunosorbent assay. **P < 0.01 and ***P < 0.001 compared to LPS-treated cells.
