A Sensitive and Selective Method for Determination of Aesculin in Cortex Fraxini by Liquid Chromatography Quadrupole Time-of-Flight Tandem Mass Spectrometry and Application in Pharmacokinetic Study
A rapid and sensitive method for determining aesculin of Cortex fraxini in rat was developed using high-performance liquid chromatography (HPLC) quadrupole time-of-flight (QTOF) tandem mass (MS/MS). Rat plasma was pretreated by fourfold methanol to remove plasma proteins. Chromatographic separation was performed on a reverse phase column. A tandem mass spectrometric detection with an electrospr...
متن کاملA quick and Sensitive Liquid Chromatography–tandem Mass Spectrometry (LC-MS) Method for the Determination of Enalapril and Enalaprilat in Human Plasma: Application to a Bioequivalence Study
A rapid and sensitive liquid chromatography–tandem mass spectrometry (LC-MS) method for the estimation of enalapril and enalaprilat in human plasma. Detection of analytes was achieved by tandem mass spectrometry with electrospray ionization (ESI) interface in positive ion mode was operated under the multiple-reaction monitoring mode. Sample pretreatment involved in a one-step protein precipitat...
متن کاملDevelopment and Application of a Validated Liquid Chromatography-Mass Spectrometry Method for the Determination of Dexchlorpheniramine Maleate in Human Plasma
A convenient liquid chromatographic-single Quadrupole mass spectrometric (LC-MS) method was developed and validated for dexchlorpheniramine maleate (INN name: chlorphenamine) determination in human plasma. The need for just a single liquid-liquid extraction with ethyl acetate and being highly sensitive were the advantages of this method. The linearity was also excellent over the range of 1...
متن کاملRapid and sensitive determination of donepezil in human plasma by liquid chromatography/tandem mass spectrometry: application to a pharmacokinetic study.
A liquid chromatography/tandem mass spectrometry (LC/MS/MS) method was developed and validated for the determination of donepezil in human plasma samples. Diphenhydramine was used as the internal standard. The collision-induced transition m/z 380 --> 91 was used to analyze donepezil in selected reaction monitoring mode. The signal intensity of the m/z 380 --> 91 transition was found to relate l...
متن کاملDetermination of Mebudipine in Human Plasma by Liquid Chromatography–tandem Mass Spectrometry
In previous studies, mebudipine, a dihydropyridine calcium channel blocker, showed a considerable potential to be used in cardiovascular diseases. The aim of the current study was to develop a valid method using reversed-phase high performance liquid chromatography coupled with electrospray ionization mass spectrometry to assay mebudipine in the human plasma. Separation was achieved on a Zorbax...
