Hypoglycemic Mechanism of Ziya Biti Tablet Based on LC-MS Metabolomics Technique
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:
2
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:
2
Compared with the model group
the rats in the Uygur medicine Ziya Biti tablet showed a healthy states
and the blood glucose were decreased(
P
<
0.05)
which indicated that Uygur medicine Ziya Biti tablet had a certain hypoglycemic effect on type 2 diabetic rats. Eight biomarkers were finally obtained according to the results. Compared with model group
L-valine and propionylcarnitine in the Uygur medicine group were decreased(
P
<
0.05)
while sphingosine-1-phosphate
LPC (16∶1/0∶0)
LPC (18∶0/0∶0)
LPC (18∶2/0∶0)
LPC 20∶1/0∶0)
PC (19∶0/0∶0) were elevated(
P
<
0.05).
Conclusion:
2
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.
