Inhibitory Effects of Chemical Compounds Isolated from the Rhizome of Smilax glabra on Nitric Oxide and Tumor Necrosis Factor-α Production in Lipopolysaccharide-Induced RAW264.7 Cell

Figure 4

The inhibitory effects of the isolated compounds on NO (a) and TNF-α (b) productions in LPS-induced RAW264.7 cells. Cells were seeded into 24-well plates and incubated for 12 h and then treated with or without different concentrations of compounds for 24 h (for NO) or 14 h (for TNF-α). The culture supernatant was analyzed for nitrite and TNF-α production. Results shown are representative of three separate experiments. All conditions were run in triplicate, and data shows mean ± SD values.
