ABSTRACT
A high-performance liquid chromatographic method has been developed for the quantitative determination of adenosine in human synovial fluid. The method is simple, rapid and, overall, selective. No interference with the components of the biological matrix was observed in these chromatographic conditions. An ODS (250 x 4.6 mm) 5 microm column was used with an isocratic elution of a phosphate buffer-acetonitrile mobile phase. Detection was carried out on a UV detector at 260 nm. Calibration curve was found to be linear in the 0.7--70 microg ml(-1) range. Linear regression analysis of the data demonstrates the efficacy of the method in terms of precision and accuracy. The precision of this method, calculated as the relative standard deviation (RSD) of the recoveries (1.57--2.21%), was excellent. The limits of quantitation (LOQ) and detection (LOD) were respectively 0.7 and 0.2 microg ml(-1). The method was applied to some samples of synovial effusion from patients affected by rheumatoid arthritis. The concentrations of adenosine which were found were included in the range of the calibration curve.
