CD （Cryptocarya densiflora） Blume has traditionally been used as an herbal medicine. In this study, the effects of CDEE （CD ethanol extract） on inflammation were investigated in LPS （lipopolysaccharide）-stimulated mouse RAW264.7 macrophages. We investigated the effects of CDEE on the production of NO, PGE2 interleukin （IL）-6, IL-1β, and tumor necrosis factor （TNF）-α in LPS-stimulated RAW264.7 cells. We measured the mRNA or protein expression of the pro-inflammatory mediators induced by CDEE in LPS-stimulated RAW264.7 cells. We explored the expression of Nrf-2, heme oxygenase （HO）-I and NADPH-quinone oxidoreductase （NQO）-I to elucidate the antioxidative mechanisms. CDEE significantly inhibited the production of NO, PGE2, IL-6, IL-1β and TNF-α in LPS-stimulated RAW264.7 cells. CDEE suppressed the mRNA or protein expression of iNOS, COX-2, and the MAPKs with a reduction in the translocation of NF-κB in LPS-stimulated RAW264.7 cells. In addition, CDEE significantly increased the expression of HO-I and NQO-1 with an increase in the translocation of Nrf-2 into the nucleus. These results indicate that CDEE inhibits the LPS-induced inflammatory and oxidative responses via suppression of NF-κB activation and the enhancement of Nrf2 activation. We suggest that CDEE may be therapeutic for treating inflammatory diseases.
