Study on the Metabolites of Brodimoprim in Rat Plasma with1H Nuclear Magnetic Resonance and Mass Spectroscopy / 分析化学

The methods of 1H Nuclear Magnetic Resonance (NMR) and mass spectroscopy were used in detecting the metabolites of brodimoprim (BDP) in rat plasma. The endogenic compounds in the plasma were removed with solid phase extraction (SPE) column firstly, then the mixture of metabolites was identified with 1H NMR and mass spectroscopy (MS). Two metabolites of BDP in the plasma at 20h were detected, they were demethyl-brodimorpim glucuronide and brodimoprim sulfurate. The study proved that the method of SPE coupled with NMR and MS can be applied to the analysis of metbolites in plasma quickly and conveniently.
