Objectives : The present study investigated Inflammatory effect of Coptidis Rhizoma in lipopolysaccharideexposed rats and Raw 264.7 cells. Methods： The plasma concentration of IL-1$eta$, IL-6 and TNF-$alpha$ peaked at 5 h after LPS injection, and the values of the Coptidis Rhizoma extract groups were lower than those of the control group. In the increment of cytokines concentration at 2 h and 5 h after LPS injection, the Coptidis Rhizoma groups were lower than that of control group. The plasma concentration of IL-10 peaked at 5 h after LPS injection, and the values of the Coptidis Rhizoma extract groups were higher than those of the control group. In the increment of cytokines concentration at 2 h and 5 h after LPS injection, the Coptidis Rhizoma groups were higher than that of control group. Liver cytokines measurement was done at 5 h after LPS injection. The concentration of liver IL-1$eta$ and IL-6 in the Coptidis Rhizoma groups was lower than that of the control group. The concentrations of liver TNF-$alpha$, and IL-10 showed no significant differences among all the treatment groups. Results： In the studies of lipopolysaccharide-exposed Raw 264.7 cells, the concentration of IL-1$eta$, IL-6 and TNF-$alpha$ in the lipopolysaccharide-exposed cells groups was higher than that of control group (normal group), and in the lipopolysaccharide-exposed cells groups, these values showed a tendency to decrease in the Coptidis Rhizoma groups. The concentration of IL-10 in the lipopolysaccharide-exposed cells groups was higher than that of control group (normal group), and in the lipopolysaccharide-exposed cells groups, the values showed a tendency to increase in the Coptidis Rhizoma groups. Conclusions： These results indicate that the Coptidis Rhizoma extracts have an functional material for Inflammatory activities.
