Abstract: The chloramphenicol in chichen was assayed with the method of solid phase extraction and high performance liquid chromatography (HPLC). The chichen sample was extracted by ethylacetate and cleaned by ENVI-18 SPE column. Then the sample was separated by the C18 column with a mobile phase of methanol and water(35:65, V/V), at the rate of 1ml/min and detected at 278nm. The RSD of this method is less than 5%, and the detection limit was 0.005μg/g.The everage recoveries was 82.4%.

Key words: chloramphenicol residues, chichen, solid phase extraction, high performance liquid chromatography(HPLC)
