Terminalia chebula(TC),a kind of Combretaceae,is a widely used herb in India and East Asia to treat cerebrovascular diseases.However,the potential mechanism of the neuroprotective effects of TC at the metabonomics level is still not unclear.The present study focused on the effects of TC on metabonomics in stroke model.In our study,rats were divided randomly into Sham,Model,and TC groups.The TC group were intragastricly administered with TC for 7 d after middle cerebral artery occlusion(MCAO)operation.The sham and the model groups received vehicle for the same length of time.Subsequently,the neuroprotective effects of TC were examined by neurological defects evalua⁃tion,infarct volume assessment,and identification of biochemical indicators for antioxidant and anti-inflammatory activi⁃ties.Further,metabonomics technology was employed to evaluate the endogenous metabolites profiling systematically.Consist to results of biochemical and histopathological assays,pattern recognition analysis showed a clear separation of the Model and the Sham group,indicating a recovery impact of TC on the MCAO rats.Moreover,12 potential biomarkers were identified in MCAO Model group,involved in energy(lactic acid,succinic acid,and fumarate),amino acids(leucine,alanine,and phenylalanine)and glycerophospholipid[PC(16∶0/20∶4),PC(20:4/20:4),LysoPC(18:0)and LysoPC(16:0)]metabolism,and other types of metabolism(arachidonic acid and palmitoylcarnitine).Notably,we found that metabolite levels of TC group were partially reversed to normal.In conclusion,TC could ameliorate MCAO rats by intervening with energy metabolism(glycolysis and TCA cycle),amino acid metabolism,glycerophospholipid metabolism and other types of metabolism.
