Anti-inflammatory activity of the extracts of ginseng berry (GBE) was investigated through the evaluation of its inhibitory effect on the production of inflammatory meditator, nitric oxide(NO), tumor necrocis factor-alpha (TNF- ${ alpha}$ ), interleukin-6 (IL-6) in LPS-induced RAW264.7 macrophage cells. GBE was fractionated using n-hexane, chloroform, ethylacetate, buthanol and $H_2O$ , sequentially. RAW264.7 cells were induced $100ng/m{ ell}$ of lipopolysaccharide (LPS) and treated with 0, 1.6, 8, 40 and $200{ mu}g/m{ ell}$ of GBE fractions. LPS-induced NO production on all of GBE fractions was inhibited with increasing added concentration of GBE fractions. Chloroform fraction of GBE was the most effective in inhibiting LPS-induced TNF- ${ alpha}$ production. Hexane, chloroform and $H_2O$ fractions of GBE exhibit strong inhibition LPS-induced IL-6 production. Especially, $H_2O$ fractions of GBE was the most effective in inhibiting LPD-induced IL-6 production without significant cytotoxicity in RAW264.7 cells, and reduced the activation of mitogen-activated protein kinases (MAPK) and IkB phosphorylation. These results indicate that $H_2O$ fractions of GBE exhibits strong anti-inflammatory effects by inhibition of NF-kB by inhibition of p-38 on MAPK and IkB phosphorylation. |
