亲水色谱-质谱联用(HILIC-MS)定量测定大鼠血浆中美金刚浓度及药代动力学研究
Quantification of memantine in rat plasma by hydrophilic interaction chromatography/tandem mass spectrometry and its application in pharmacokinetics
摘要
Abstract
Objective To establish a liquid chromatography/tandem mass spectrometry employing hydrophilic interac-tion chromatography with mass spectrometry( HILIC-MS )method for determining memantine in rat plasma. Methods The sample preparation consisted of a protein precipitation extraction and was determined by HILIC-MS. The positive ion selecte-ol ion monitoring ( SIM ) mode was performed and the detective ions m/z 180 and 285 were used to measure memantine and Ro 64-0802 ( I. S. ). The chromatographic separation was achieved using an Amide-80( 4. 6 mm x 100 mm,5 μm )analytical column with an isocratic mobile phase composed of acetonitrile-water-formic acid( 70: 30: 0. 1, v/v/v, 0. 35 ml/min ). Results The method was linear over a concentration range of 2 to 500 ng/ml. The LLOQ was 2 ng/ml. The average inter-day and intra-day precision values was in 3. 9% and 5. 6% , while the accuracy value was in 84. 9% - 111. 2% . Conclu-sion Using this method, retention time is greatly improved, and the matrix effects are decreased by HILIC-MS. This method has been successfully applied to the preclinical and clinical research of memantine.关键词
