Red ginseng (RG) and fermented red ginseng (FRG) are produced from ginseng (GS) via certain biological processes. The main difference between three ginsengs is the composition of ginsenosides known as major metabolites having several biological activities. The concentration of the metabolites has been known to be dependent on the methods which make RG and FRG In this study, we investigated the effects of WG, RG and FRG on the productions of inflammatory proteins (NF-κB, iNOS, COX-2) and cytokines (TNF-α, INF-γ) in LPS-stimulated RAW 264.7 cells. The levels of NO production and iNOS expression were suppressed by the treatment of white ginseng (WG), RG and FRG in LPS-stimulated cells. Also, the production of TNF-α and INF-γ was decreased in the cells by all of them. It was indicated that the inhibition of NF-κB activation in LPS-stimulated cells treated with three kinds of ginsengs was resulted from the suppression of the level of COX-2 expression and the phosphorylation of IκB by LPS. The present study indicated that RG showed the best biological activity among them and FRG was better than WG. The better activity of RG on the inhibition of NO production is considered to be caused by the difference of ginsenoside composition produced during their preparations. In order to elucidate the mechanism, animal test should be performed with three ginsengs.
