Canavalia gladiata, known as sword bean, has been used as a Chinese traditional medicine for anti-inflammatory effects. However, the action mechanisms of sword bean have not yet been clearly defined. In the present study, the whole parts of a ripened sword bean (RSB) and the green sword bean (GSB) containing bean pod were extracted with ethanol by reflux extraction. The two crude extracts (RSBE and GSBE) from RSB and GSB were validated by a liquid chromatography-tandem mass spectrometry (LC/MS/MS) analysis of gallic acid as a reference chemical. The anti-inflammatory effects of two sword bean extracts were extensively investigated using LPS-stimulated macrophage cells. First, RSBE and GSBE significantly inhibited the production of pro-inflammatory mediators, such as tumor necrosis factor-
