Metabolite profiling ofl-isocorypalmine in rat urine, plasma, and feces after oral administration using high performance liquid chromatography coupled to Fourier transform ion cyclotron resonance mass spectrometry

l ‐Isocorypalmine, an active alkaloid compound isolated from Rhizoma Corydalis yanhusuo , has been reported to possess biological activity for treating cocaine use disorder. A high‐performance liquid chromatography coupled to Fourier transform ion cyclotron resonance mass spectrometry method was established for identification of the metabolites of l ‐isocorypalmine in urine, plasma and feces samples of rats after a single intragastric gavage of...
