Popis: To explore the possible mechanism of Yunaconitine poisoning by studying the changes of urine metabolic profile in rats chronically poisoned by Yunaconitine via non-targeted metabolomics.A rat model of Yunaconitine poisoning was established, and a metabolomics method based on UPLC-QTOF-MS technology was used to obtain the urine metabolic profile. Principal component analysis (PCA), orthogonal projections to latent structures-discriminant analysis (OPLS-DA), variable importance in projection (VIP) value greater than 1, fold change (FC) value greater than 3 or less than 0.33 andSixteen potential biomarkers includingYunaconitine may cause neurotoxicity, hepatotoxicity and cardiotoxicity by affecting amino acid and glucose metabolism.
