title: Gas-chromatographic determination of dyphylline in serum and saliva.
abstract: We describe a simple determination of dyphylline in serum and saliva by gas chromatography after solvent extraction. Dyphylline concentrations were found to be about 36% higher in saliva than in the corresponding serum.
