| 摘 要： | 采用高效液相色谱-串联质谱仪(HPLC-MS/MS)建立了猕猴桃、黄瓜、苹果和葡萄4种果蔬中噻苯隆残留的分析方法。样品经乙腈提取,N-丙基乙二胺(PSA)净化,HPLC-MS/MS测定。结果表明:在0.01~1 mg/L范围内,不同基质中噻苯隆的峰面积与其质量浓度间呈良好线性关系,决定系数均大于0.99;在0.01、0.05和0.5 mg/kg添加水平下,4种果蔬基质中噻苯隆的平均回收率为87%~102%,相对标准偏差(RSD)为0.8%~2.0%;方法定量限(LOQ)为0.01 mg/kg。该方法操作简单、高效、经济,准确度和精密度均满足残留分析的要求,适用于噻苯隆的残留检测。

| Abstract: | An analytical method for the determination of thidiazuron in kiwi, cucumber, apple and grape was established using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS). The samples were extracted with acetonitrile, purified by primary secondary amine (PSA) and detected with HPLC-MS/MS. The results indicated that in the concentration of 0.01-1 mg/L, the matrix-matched calibration curves showed good linearity and determination coefficients >0.99. In the concentration of 0.01-0.5 mg/kg, the average recoveries of thidiazuron in the four matrices were found between 87% and 102% with 0.8%-2.0% relative standard deviations (RSD).The limits of quantification (LOQ) were 0.01 mg/kg. The method was convenient, efficient, economical, sensitive and accurate, which can be suitable for determination of thidiazuron residues. |
