摘要:	A semi-micro high performance liquid chromatography (HPLC) was developed to determine clenbuterol in pork, beef and hog liver. The procedure included extraction with 0.4 N perchloric acid, partitionally separation with diethyl ether, and then back-extraction with 0.2 M sulphuric acid. Analytical procedure was performed by HPLC with a Waters Cosmosil column 5CI8-MS (2.0 x 150 mm), a mobile phase of 0.05 M NaH2PO4 (pH3.0)/acetonitrile solution (80/20, v/v) and absorbance at 212 nm. The recoveries of clenbuterol in pork, beef and hog liver spiked with standards of 0.0005 similar to 0.01 ppm were 80.9 similar to 90.6 %. The detection limit of clenbuterol in tested samples was 0.0001 ppm, which is lower than the officially allowed level. The equation was linear for detecting 0.0002 similar to 0.001 ppm clenbuterol. The method was validated to be usable for market samples. Three out of 150 samples were detected to contain clenbuterol (0.0001 similar to 0.00015 ppm), which were less than both JECFA and Department of Health regulation levels (hog liver 0.0006 ppm and beef 0.0002 ppm).
