Cyperus rotundus is a multipurpose plant, extensively used in traditional medicine around the world to treat stomach ailments, wounds, boils and blisters. A number of pharmacological and biological activities including anti-Candida, anti-inflammatory, antidiabetic, antidiarrhoeal, cytoprotective, antimutagenic, antimicrobial, antibacterial, antioxidant, cytotoxic and apoptotic, anti-pyretic and analgesic activities have been reported for this plant. In the present study, the water and 70% ethanol extracts showed no significant effect on NO production, and NF-κB SEAP reporter gene assay using LPS-stimulated RAW264.7 cells, murine macrophages. Similarly, the anti-inflammatory effects of seventeen essential oils isolated from C. rotundus were evaluated on LPS-stimulated RAW264.7 cells. From the tested compounds, α-cyperone, nootkatone, carophylline oxide, oleanolic acid, showed promising anti-inflammatory and NF-κB inhibition effect on LPS-stimulated RAW264.7 cells. Furthermore, the anti-inflammatory potential of four structurally divergent sesquiterpens (nootkatone, α-cyperone, valencene and β-selinene) were brought under molecular investigation in terms of LPS-stimulated RAW264.7 cells. Moreover, the nootkatoon, α-cyperone, were selected for detail study in order to evaluate various inflammatory mediators (iNOS and COX-2). The results showed that, nootkatone, α-cyperone, down-regulated the expressions of iNOS and COX-2 and correlated with the suppression of NF-κB signaling pathway. Additionally, electrophoretic mobility shift assay (EMSA) elucidated that nootkatone and α -cyperone dramatically suppressed LPS-induced NF-κB-DNA binding activity using 32P-labeled NF-κB probe. Hence, our data suggest that α-cyperone and nootkatone are potential therapeutic agents for inflammation associated diseases.
