High performance liquid chromatographic method for the determination of theophylline in biological fluids (serum, saliva and urine) was developed. Theophylline in biological fluids was adsorbed on a diatom earth column, followed by elution with a mixture of chloroform-isopropanol (95 : 5). After evaporation of the solvent, the residue was dissolved in water, injected onto a HPLC column packed with an ODS stationary phase eluted at 40℃ with a mixture of 0.1M phosphate buffer (pH 5.3)-acetonitrile (9 : 1) and detected at 273 nm. 8-Chlorotheophylline was used as an internal standard. The recovery of theophylline from serum by this method was 100.1%±1.76% (SD ; n=5), Other xanthine derivatives (theobromine and caffeine) were seperated under the same conditions.
