The anti-inflammatory activities of an ethanol extract of Caesalpinia sappan L. (CS) were investigated in LPS-induced RAW 264.7 cells. Result indicated that CS inhibited the LPS-induced NO production in a dose-dependent manner with an $IC_{50}$ of $10.9\;{\mu}g/mL$. In addition, CS attenuated the iNOS mRNA and protein expression by inhibiting NF-${\kappa}B$ activation. CS also suppressed the productions of IL-6 and MCP-1 in a dose-dependent manner, with $IC_{50}$ values of $15.9\;{\mu}g/mL$ and $5.47\;{\mu}g/mL$, respectively. In addition to the anti-inflammatory activities, CS decreased intracellular ROS formation in the same cells. In conclusion, CS inhibited the production of NO, IL-6 and MCP-1 via a suppression of the NF-${\kappa}B$ activation and intracellular ROS generation.
