ABSTRACT
<p><b>OBJECTIVE</b>To determine the pesticide residues in Shengmaiyin.</p><p><b>METHOD</b>The residues were simultaneously identified and quantified by capillary gas chromatography. The capillary column was OV-1701(0. 32 mm x 30 m, 0.5 microm), splitless injection and Agilent 63Ni electron capture detector ECD were adopted. The carrier gas were high-pure nitrogen, the flow rate were 60 mL x min(-1), the injector temperature was 260 degrees C, and the detector temperature was 300 degrees C.</p><p><b>RESULT</b>It showed a good linear relationship between peak area and pesticide concentration for 11 kinds of pesticides in the detection concentration range. All correlation coefficients were higher than 0.996 2. The average recovery was 83.1% -114.7%.</p><p><b>CONCLUSION</b>A simple and efficient monitoring method of pesticide residues is established which provides the foundation for the safe use and analysis of Shengmaiyin.</p>
