摘要： A simple chiral high-performance liquid chromatography method with diode array detector was developed and validated for stereoselective determination of tetraconazole enantiomers in cucumber, muskmelon, and soils. Good separation was achieved at 20°C using cellulose tris-(4-methylbenzoate) as chiral stationary phase, a mixture of n-hexane and ethanol (90:10) as mobile phase at a flow rate of 0.8 ml/min. The assay method was linear over a range of concentrations (0.5-50 μg/ml) and the mean recoveries in all samples were more than 85% for the two enantiomers. The limits of detection for both enantiomers in plant and soil samples were 0.06 and 0.12 μg/g, respectively. Then, the proposed method was successfully applied to the study of enantioselective degradation of rac-tetraconazole in cucumber, muskmelon, and soils. The results showed that the degradation of two enantiomers of tetraconazole followed first-order kinetics and significantly stereoselective behavior was observed in cucumber, muskmelon, and Beijing soil. The preferential absorption and degradation of (-)-S-tetraconzole resulted in an enrichment of the (+)-R-tetraconazole residue in plant samples, whereas the (+)-R-tetraconazole showed a faster degradation in Beijing soil and the stereoselectivity might be caused by microorganisms. No stereoselective degradation was observed in Heilongjiang soil.
