Sandalwood Essential Oil의 iNOS 발현과 염증성사이토카인의 생성에 미치는 영향

Effects of Sandalwood Essential Oil on the iNOS Expression and Proinflammatory Cytokine Production

The present study was designed to determine the effect of the Sandalwood Essential Oil (Santalum album) on pro-inflammatory factors such as NO, iNOS expression and IL-1β, IL-6, TNF-α in lipopolysaccharide (LPS) - stimulated RAW264.7 macrophages cells. The cell toxicity was determined by MTS assay. To evaluate of anti-inflammatory effect of Sandalwood Essential Oil, amount of NO was measured using the NO detection kit and the iNOS expression was measured by western blot analysis and reverse transcriptase polymerase chain reaction (RT-PCR). And proinflammatory cytokines were measured by ELISA kit. As a result, Sandalwood Essential Oil reduced NO, iNOS expression and IL-1β, IL-6, TNF- α production without cytotoxicity. Our results suggest that the Sandalwood Essential Oil may have an anti-inflammatory property through suppressing inflammatory mediator productions and appears to be useful as an anti-inflammatory oil.
