Abstract:
OBJECTIVE To study main way and target of Euphorbia kansui after stir-frying with vinegar. METHODS 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 metabolite 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 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 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.
