Objective: The inflammatory model in vitro was used to evaluate the anti-inflammatory mechanism of Polygala japonica effective ingredients.Method: RAW264.7 macrophage line was induced by lipopolysaccharide(LPS) to set up the inflammatory model.To study the effect of P.japonica effective ingredients on the inflammation factors by assaying the concentration of nitric oxide(NO)
tumor necrosis factor-α(TNF-α) and interleukin-6(IL-6).The mRNA expression of TNF-α and IL-6 was assayed with real-time quantitative polymerase chain reaction(PCR) too.Result:P.japonica effective ingredients could significantly reduce the release of NO
IL-6 and TNF-α in LPS-induced RAW264.7 macrophage line
and obviously decrease the mRNA expression of TNF-α and IL-6
too.Conclusion:The anti-inflammatory mechanism of P.japonica effective ingredients may be related to reducing the release of inflammation factors in macrophage cell and inhibiting the mRNA expression of TNF-α and IL-6.
