title: Gas chromatographic determination of 5-fluorocytosine: a modified extraction method.
abstract: A modified procedure for the gas-chromatographic determination of 5-fluorocytosine in serum is described. A more volatile solvent mixture for extraction is used to reduce sample preparation time before chromatography. Comparison of values from assay of 12 serum samples by our method and the reference method gave a correlation coefficient of 0.99.
