Objective:To study the anti-inflammatory effect of the ethanol extract of Coptis chinensis vitro.Methods: An inflammatory cell model was established by stimulating the mouse peritoneal macrophages in vitro with lipopolysaccharide(LPS).LPS stimulated of RAW264.7 cells for a long time after administration of intervention.Effect of ethanol extract of Coptis chinensis Franch.on RAW264.7 cell growth activity was analyzed by MTT assay.The production of tumor necrosis factor-α(TNF-α),IL-1β,IL-6,NO,prostaglandin E2(PGE2) was determined by ELISA.The expression of mRNA of TNF-α,induced nitric oxide synthase(iNos) and HO-1 was detected by real-time fluorescent quantitative PCR(RT-PCR).Results: The ethanol extract of Coptis chinensis had no inhibition effect on the scope of RAW 264.7 cells the scope of 5-80 mg/L.Each treatment group concentration of interleukin-6 (IL-6),interleukin-1β (IL-1β),TNF-α,NO,prostaglandin E2 (PGE2) content of LPS stimulation model group were significantly (P<0.01),and content was not related to concentration.Real-time quantitative (RT-PCR) showed,the concentration of each treatment group were significantly lower iNos,HO-1 and TNF-α mRNA expression (P<0.05,P<0.05,P<0.01),and content was not related to concentration.Conclusion: Coptis chinensis Franch.ethanol extract has anti-inflammatory effects in vitro,the mechanism may be related to inhibition of TNF-α,NO and other inflammatory factors and the impact of the activation of arachidonic acid (AA) metabolism.
