Objective : Nelumbinis Folium (NF) is used for diarrhea, headache and dizziness in traditional medicine. In this paper, we examined the anti-inflammatory effects of the methanol extract of NF in mouse macrophages. Methods : Peritoneal macrophages from thioglycollate medium-injected mice were cultured and stimulated with lipopolysaccharide(LPS) or LPS/interferon(IFN)-${gamma}$ for viability assay, cytokine measurement and Western blotting. Results : NF methanol extract suppressed the levels of nitric oxide (NO) through reduction of inducible NO synthase in a concentration-dependent manner. The extract reduced LPS/IFN-${gamma}$-stimulated STAT1 phosphorylation and LPS-induced $I{kappa}B{alpha}$ degradation through inhibition of $I{kappa}B{alpha}$ kinase activation. The extract also inhibited p38, JNK/SAPK and ERK1/2 activation. Conclusions : Our findings suggested that NF has anti-inflammatory activity, and have a potential for therapeutic application. Further research is required to investigate its anti-inflammatory active compounds.
