A high\u2010performance liquid chromatography coupled to Fourier transform ion cyclotron resonance mass spectrometry method was established for identification of the metabolites of <jats:sc>l<\/jats:sc>\u2010isocorypalmine in urine, plasma and feces samples of rats after a single intragastric gavage of <jats:sc>l<\/jats:sc>\u2010isocorypalmine at a dose of 15\u00a0mg\/kg. As a result, a total of 21 metabolites (six phase \u0406 metabolites and fifteen phase II metabolites) were detected and tentatively identified by mass spectrometry and fragment ions from tandem mass spectrometry spectra. All metabolites were present in the urine samples, nine metabolites were found in the plasma samples and three metabolites were found in the feces samples. Results indicated that metabolic pathways of <jats:sc>l<\/jats:sc>\u2010isocorypalmine included oxidation, dehydrogenation, demethylation, sulfate conjugation, and glucuronide conjugation. In addition, glucuronidation was the major metabolic reaction. Results of this investigation could provide significant experimental basis for efficacy, safety and action mechanism of <jats:sc>l<\/jats:sc>\u2010isocorypalmine, which will be advantageous to new drug development for treating cocaine addiction.<\/jats:p>","DOI":"10.1002\/jssc.201800745","type":"journal-article","created":{"date-parts":[[2018,10,31]],"date-time":"2018-10-31T07:39:14Z","timestamp":1540971554000},"page":"619-627","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Metabolite profiling of <scp>l<\/scp>\u2010isocorypalmine in rat urine, plasma, and feces after oral administration using high performance liquid chromatography coupled to Fourier transform ion cyclotron resonance mass spectrometry"],"prefix":"10.1002","volume":"42","author":[{"given":"Yiran","family":"Li","sequence":"first","affiliation":[{"name":"School of Pharmacy Shenyang Pharmaceutical University  Shenyang Liaoning Province P.
