Abstract:

With the application of 1H nuclear magnetic resonance(1H NMR) spectroscopy, we studied the effect of Huanglian Jiedu decoction(HJD) on the metabonomics of brown adipose tissue extracts in high fructose-induced insulin resistance model. 32 Wistar rats were divided into four groups, i.e., controls, model group, positive drug group and HJD treated group, 8 in each group. The last three groups were given 100 g/L fructose water for 28 d to establish insulin resistance model, normal control group was given the equal volume of pure water at the same time. After 28 d, four groups of rats were given 100 g/L fructose water continuously. Rats in positive drug group were administered orally atorvastain at a dose of 10 mg/(kg·d), and rats in HJD treated group were given by gavage with HJD water. The control and model groups were given by gavage with a certain volume of saline solution, and the experiment lasted 56 d. Brown adipose tissues were obtained and 1H NMR spectra of each sample was performed and analyzed by principal component analysis(PCA)method. Compared with the control group, lactate, alanine, choline, phosphocholine/glycerol phosphocholine(PC/GPC), creatine/creatinine, taurine and inosine increased in the model and lipid decreased. In comparison with model group, the myo-inositol was increased in HJD group, and HJD had reversed the metabolites in the model group. HJD can regulate the body’s energy metabolism and reduce the damaged cell membrances and the injury of liver and kidney. Therefore, this study elucidates the metabolic mechanism of HJD on insulin resistance(IR).
