| 摘 要： | 建立了测定葡萄及土壤中吡唑醚菌酯残留的液相色谱检测方法。样品以二氯甲烷提取和固相萃取柱（SPEC18柱）萃取净化，反向高效液相色谱法测定，乙腈和水（70＋30）为流动相，C18色谱柱分离，278nm紫外定量检测吡唑醚菌酯。该方法吡唑醚菌酯的最小检出量为2×10^-10g，线性相关系数为0．9986，葡萄及土壤加标回收率分别为80．4％-94．1％、81．8％。98．4％．相对标准偏差（RSD）分别为1．8％～3．8％、2．6％-3．0％。方法具有简便、快捷。准确的特点，适合葡萄及土壤中吡唑醚菌酯残留量的测定。

| Abstract: | A HPLC method for the determination of pyraclostrobin residues in grape and soil. was developed. Pyraclostrobin were extracted from the samples with dichloromethane, cleaned up with SPE-C18 and analyzed by HPLC with C18 column, acetonitrile/water （70/30, by volume） as mobile phase and UV detector at 278nm. The results showed that the minimum detectable amount was 2xl0-1~g, the linear correlation was 0.998 6, the average recoveries were in the range of 80.4%-94.1% and 81.8%-98.4%, the RSD were 1.8%-3.8% and 2.6%-3.0% for grape and soil respectively. The method was sensitive, precise, rapid and simple. It was applicable to the determination of pyraclostrobin residues in grape and soil. |
