A simple and rapid gas chromatographic determination of clopidol in chicken muscle and egg was studied. After extraction with methanol from homogenized sample, the extract was cleaned up with an ion exchange resin column. Clopidol obtained was methylated with diazomethane and the resulting methyl-clopidol was determined by ECD-GC with a column (2 m×3 mm i.d.) of 10 % DC-200 on Gaschrom Q. Linear calibration curves for the gas chromatographic determination were obtained in the range of 0.01 to 0.1μg/ml for clopidol. The recoveries of clopidol added to chicken muscle and egg were 94.4 % and 93.3 % on the average, respectively. The detection limit of clopidol in this analytical procedure was 0.01μg/g in chicken muscle and egg. The analysis of actually commercial sample indicated that clopidol was detected in 44.0 % of chicken muscle and in 28.0 % of egg, and that clopidol detected was in the range of 0.30 to 3.84 μg/g for chicken muscle and 0.01 to 0.14μg/g for egg.
