Description
Summary:The analysis of arildone in plasma, urine and feces by gas—liquid chromatography with electron-capture detection is described. O-(2,3,4,5,6-Pentafluorohenzyl)hydroxylamine is the derivatizing agent for the plasma and urine analysis; 3-nitrophenylhydrazine is utilized for fecal analysis. The mean (± S.E.) minimum quantifiable level of arildone was 1.4 (± 0.2) ng/ml in urine, 6.4 (± 0.1) ng/ml in plasma, and 12.6 (± 1.0) ng/g in feces. The chromatographic response was linear in the range of 0 and 10–120 ng/ml for plasma, 0 and 2.5–20 ng/ml for urine and 0 and 25–250 ng/g for feces. The estimated overall precision of the assay was 5.5%, 6.4% and 8.9% in urine, plasma and feces, respectively.
