The study investigated the molecular mechanism of anti-inflamatory activity of Pluchea indica leaf extract in lipopolysaccharide (LPS)-stimulated RAW 264.7 macrophages. The ethyl acetate fraction of ethanol extract of Pluchea indica leaves (EFPI) exhibited a potent inhibitory effect on NO production in LPS-induced macrophages and inhibited PGE2 release. EFPI reduced iNOS mRNA and protein expression through suppressed iNOS promoter activity and nuclear translocation of subunit p65 of nuclear factor-κB, though it did not inhibit phosphorylation of the mitogen-activated protein kinases (MAPKs). Finally, EFPI possessed anti-inflamatory activities on the acute phase of inflammation as seen in EPP-induced ear edema and carrageenan-induced paw edema in rats.
