Biotransformation and Metabolic Profile of Limonin in Rat Liver Microsomes, Bile, and Urine by High-Performance Liquid Chromatography Coupled with Quadrupole Time-of-Flight Mass Spectrometry
which has significant biological activities. However, the metabolic profile of limonin has not been fully understood. To expound its metabolism in vivo and in vitro, the metabolites of limonin was studied by rat livermicrosomes, urine, and bile. High-performance liquid chromatography/quadrupole time-of-flight mass spectrometry was used for identification. Among the metabolites, the structures of M1
