[Anti-inflammation effect of Jinlingzi San in rat metabonomics based on 1H-NMR and LC-MS technology]

To further explore the regulatory effect of Jinlingzi San on in vivo inflammatory mechanism during inflammatory treatment, this study adopted 1H-NMR and LC-MS technology to analyze differences in in vivo metabolites of carrageen-induce rat foot swelling model. Besides, biomarkers related to inflammation models of Jinlingzi San in SD rats were discovered to speculate the regulatory mechanism of Jinlingzi San in resisting carrageen-induce inflammation. Through the analysis of detection spectrum, we found 18 biomarkers of metabolites(citrate, pyruvate, malic acid, succinate, glutamate, lysine, tartrate, 2-oxobutyric acid, glycine, guanosine, 9-cis-retinoic acid, triphosphate, inosine 5'-diphosphate, inosine diphosphate, tripolyphosphate, inorganic triphosphate, glycerophosphocholine, 21-deoxycortisol). Relevant pathway analysis results were TCA cycle, pyruvate metabolism, glycine, serine and threonine metabolism, and dicarboxylic acid metabolism. From the metabolic network, we can see that the anti-inflammatory effect of Jinlingzi San can regulate citric acid, succinic acid and glycine content to resist oxygen free radical and reduce body damage by ROS, so as to down-regulate inflammatory factors generated from body tissues and resist inflammation.
