Main ways and target prediction of detoxification mechanism of Euphorbia kansui after stir-frying with vinegar
Twenty-four SPF grade SD rats were randomly divided into blank group,
E. kansui
group (850 mg/kg) and vinegar
stir-fried
E. kansui
group (850 mg/kg), with 8 rats in each group. Blank group was given 0.5% sodium carboxymethyl cellulose solution intragastrically, and
E. kansui
group and vinegar
stir-fried
E. kansui
group were given relevant test sample for consecutive 20 d. The rats’ urine of 12 hours was collected on the 20th day. The urine samples of rats in each group were determined by UPLC-Q-Exactive-MS. The data was pre-processed by Compound Discoverer 3.0 software, and the metaboli
te structure was identified by BioCyc, HMDB and other databases. Whether different groups presented their own clustering phenomenon was observed by principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA), etc. Based on the pathway analysis of MetaboAnalyst, the potential targets of detoxification mechanism of
E. kansui
after stir-frying with vinegar were predicted.
RESULTS
2
Twenty significantly differential endogenous metabolites were identified, of which 10 target metabolites, such as
N
-acetyl-L-aspartate and 3-phosphonooxypyruvic acid, were targets of detoxification mechanism of
E. kansui
after stir-frying with vinegar. The main metabolic pathways included arginine biosynthesis, alanine, aspartic acid and glutamic acid metabolism, cysteine and methionine metabolism, and arginine and D-ornithine metabolism. The biological significance of all related metabolites in the pathways was analyzed and speculated; after stir-frying with vinegar,
E. kansui
may alleviate neurotoxicity by reducing the level of
N
-acetyl-L-aspartic acid;
E. kansui
had a protective effect on cardio-cerebrovascular system by increasing the level of L-high arginine.
CONCLUSIONS
2
After stir-frying with vinegar,
E. kansui
can significantly improve the adverse factors in terms of nervous system, cardio-cerebrovascular system, immune system and energy metabolism. The most concentrated metabolic pathway related to its detoxification mechanism is arginine biosynthesis.
