초록

This study was to develop a quantification method of lisinopril using liquid chromatography tendem mass spectrometry in human plasma. Quntitation of lisinopril by MRM(multiple reaction monitoring) in the electrospray positive mode was validated according to FDA guideline. Extraction of lisinopril and enalapril as internal standard from plasma was perfomed by means solide phase extraction. The calibration curve of lisinopril showed a good linerarity in the concentration range 2∼200ng/ml. The coefficients of variations for the inter-day and intra-day precision was less than 15%, and the inter-day and intra-day accuracy was 97.6∼101.0%. (omitted)
