Abstract:

Herein, metabolites in plasma, urine and feces of rats were analyzed after oral administration of rutin and the metabolic pathway of rutin was evaluated. After intragastric administration of 250 mg/kg rutin, plasma, urine, and feces were collected and treated via solid phase extraction. Ultra-high performance liquid chromatography-Q Exactive hybrid quadrupole-orbitrapmass spectrometry (UPLC-Q-Orbitrap MS) was used with 0.05% formic acid water (A)-0.05% formic acid acetonitrile (B) as mobile phase gradient elution. The sample data were collected in positive- and negative-ion modes. The metabolites and metabolic pathway of rutin in rats were determined via high resolution extraction ion chromatography in the parallel reaction monitoring mode, combined with chromatographic retention time, accurate mass measurement and diagnostic ions.Twenty-nine rutin metabolites were detected and identified in positive and negative ion modes,and their main metabolic pathways were methylation, glucuronidation, sulfation and their compound reaction. The study provided the overall metabolic profile of rutin, which will provide a reference for further pharmacodynamic evaluation, development, and utilization in the future and offer a comprehensive research method for drug metabolism identification.

Key words: rutin, UPLC-Q-Orbitrap MS, metabolites, metabolic pathways
