    Abstract:
    This study investigated the intestinal anti-inflammatory action of ginsenoside Rf in inflammatory bowel disease (IBD). IBD is a chronic inflammatory disease that affects the intestinal tract. It is associated with elevated levels of various inflammatory mediators, including interleukin (IL)-1β, IL-6, tumor necrosis factor-α (TNF-α), nitric oxide (NO), and reactive oxygen species (ROS). Ginsenosides, the main active constituents of ginseng, have been reported to exert potent therapeutic effects against diverse diseases. However, ginsenoside Rf treatment for inflammation has not yet been examined. In this study, we evaluated the inhibitory effect of ginsenoside Rf on the inflammatory mediators downstream of p38/NF-kB activation on TNF-α-stimulated intestinal epithelial cells (HT-29) and mouse macrophage cells (RAW264.7). Our results showed that ginsenoside Rf significantly reduced the production of IL-1β, IL-6, TNF-α, NO, and ROS, which are most highly activated in IBD. In addition, ginsenoside Rf significantly suppressed TNF-α/LPS-induced NF-κB transcriptional activity. These results suggest that ginsenoside Rf contains a compound that has potent intestinal anti-inflammatory effects that could be used to treat diseases such as IBD.
