Nucleotides, nucleosides, and purine bases were extracted from human endomyocardial biopsies, freeze-clamped rat hearts, and porcine coronary sinus plasma. Perchloric acid extracts were neutralized with Freon-trioctylamine and analyzed at 250 nm by reverse-phase ion-pairing high-performance liquid c

β¦ Synopsis
The concentrations of radioactive and nonradioactive purine bases, purine nucleosides, purine mono-, di-, and trinucleotides in acid extracts of fibroblasts were determined by anion-exchange column chromatography. The concentrations ofnonradioactive components were determined by computerized integration of the signal from a double-beam uv-detector. The radioactive metabolites were quantitated by high-efficiency, continuous liquid scintillation counting, employing a discrete sample transport system.

A high-performance liquid chromatography (HPLC) method is described for the separation and quantitation of nucleotides, nucleosides, purine bases, and related compounds in one single run. The separation of a standard mixture of at least 24 components is achieved within 35 min on glass columns (30 cm
A single-column high-performance liquid chromatographic system for the simultaneous separation of bases, nucleosides and nucleoside mono-and polyphosphates has been developed, in which a strong porous anion-exchange resin (Aminex A-14) is used. The chromatographic run, carried out at 55" and at alka
## Abstract Theophylline, tolbutamide, mephenytoin, debrisoquin, and dapsone are marker substrates for CYP1A2, CYP2C9, CYP2C19, CYP2D6, and CYP3A4, respectively. A silicaβbased monolithic column (Chromolith SpeedROD RPβ18e, 50Γ4.6 mm) was used to separate these five marker substrates of cytochrome
