Cerebral ischemic stroke (CIS) is a kind of acute cerebrovascular disease with fast onset, low-cure rate, and high case-fatality rate. The application of Aconitum coreanum on CIS was recorded in many ancient books in China with it mechanism and effective components unclear. This study aimed to analyze the potential mechanism and effetvie components of A. coreanum on treating CIS. Neurological function score, cerebral infarction rate, and inflammatory indicators were applied to evaluate the efficacy of A. coreanum on gerbils with CIS. The prototype compounds in A. coreanum which were absorbed into blood was analyzed and identified by Ultra high performance liquid chromatography-Q exactive focus-Mass spectrometer (UPLC-QE-MS). And bioinformatics analysis was used to predict their potential targets or pathways of action. Western blotting and immunofluorescence were adopted to validate the targets or pathway with high relation. After treatment with A. coreanum, the neurological function status of gerbils with CIS was significantly improved, the ischemic area of the brain and the levels of inflammatory indicators significantly reduced. 22 prototype compounds in A. coreanum absorbed into blood were identified mainly including C-20 and C-19 diterpenoid alkaloids. Gene ontology (GO) function enrichment analysis illustrated that A. coreanum acted on protein phosphorylation, receptor complexes, protein kinase activity, and inflammatory response to impove CIS. The kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis results revealed that PI3K/Akt signaling pathway was a key pathway. Western blotting and immunofluorescence validated that A. coreanum acted on PI3K/Akt signaling pathway. In conclusion, A. coreanum improved the inflammantory condition in CIS by acting on PI3K/Akt signaling pathway and the effective components were the diterpenoid alkaloids in it.
