ABSTRACT
Objective: To observe the hypoglycemic effect of Uygur medicine Ziya Biti tablet on the type 2 diabetic rats, and analyze the hypoglycemic mechanism based on metabolomic techniques. Method: According to the results of clinical research about different origins of Ziya Biti tablet, the optimal composition was screened out; type 2 diabetic rats were taken as an experimental object in the pharmacodynamic experiments;the control group and model group were given the same dose of normal saline, Ziya Biti bablet group was given 300 mg·kg-1, the metformin group was given 300 mg·kg-1 metformin hydrochloride. The fasting blood and weight changes of the experimental group after the treatment were recorded and compared with normal group; ultra-high performance liquid chromatography-linear ion trap/electrostatic field orbit trap combined-type high resolution mass spectrometry (UHPLC-LTQ/Orbitrap MS) technology was used to conduct the metabolomics analysis on the rat serum, and principal component analysis (PCA), partial least squares discriminant analysis (OPLS-DA) on different groups of rat serum metabolites were performed to identify potential biomarkers. Result:Compared with the model group, the rats in the Uygur medicine Ziya Biti tablet showed a healthy states, and the blood glucose were decreased(PPPConclusion:The experimental results showed that Uygur medicine Ziya Biti tablet can reduce the blood glucose of type 2 diabetic rats and allivate general physiological characteristics. The mechanism of action may be related to the improvement of amino acid metabolism and lipid metabolism.
