Abstract
Four degradation products resulted from acidic hydrolysis of lisinopril under drastic conditions. The degradation products were detected by means of ultra-performance liquid chromatography coupled with mass/mass spectroscopy (LC-MS/MS) with simple and sensitive method suitable for LC-MS/MS analysis. The fragmentation behaviors of lisinopril and degradation products were investigated. Two degradation products were described in E.Ph.(8th) as impurities. Both of 6-amino-2-((1-carboxy-3-phenylpropyl)amino) hexanoic acid(m/z 309+)and 1-(2,6-diaminohexanoyl)pyrrolidine-2-carboxylic acid (m/z 244+) were formed and identified.
