摘要：

A method for the determination of the clofencet of chemical hybridizing agent SQ-1 in wheat has been established by high performance liquid chromatography. SQ-1 was extracted with 75% of ethanol and cleaned up by extraction and stripping technique. Diamonsil C-18 column with the mobile phase consisted of methanol-water (60:40, V/V, including 0.5% ammonium hydrogen phosphate, pH 2.5) at a flow rate of 1.0 mL/min was used for the detection at wave length of 283 nm. A good linear relationship was obtained in the range of 0.75 - 25.0 mg/L with the correlation coefficient 0.9999. The average recoveries of SQ-1 were 84.2% - 95.0%, the RSD were 1.0% - 3.3%, and the detection limit was 0.075 mg/L.
