In the present study, effects of essential oils isolated from various plants have been evaluated on lipopolysaccharide (LPS)-induced release of nitric oxide (NO), prostaglandin E2(PGE2) and tumor necrosis factor-α(TNF-α) by the macrophage RAW 264.7 cells. Among the tested essential oils, essential oil of Lingularia fischeri var. spiciformis (LF-oil) signifcantly inhibited the LPS-induced generation of NO, PGE2 and TNF-αIn Raw 264.7 cells. Consistent with these observations, the expression of inducible NO synthase (Inos) and cyclooxygenase (COX)-2 enzyme was inhibited by LF-oil in a concentration- dependent manner Thus, this study suggests that inhibition of release of Inos, COX-2 expression, and TNF-α By the essential oil of Lingularia fischer may be one of the mechanisms responsible for the anti-inflammatory effects of this medicinal plant.
