摘要: 目的:建立反相高效液相色谱-二极管阵列检测器测定灯笼果中杀菌剂噻菌灵残留的分析法。方法:色谱柱为Shim-pack VP-ODS(150mm×4.6mm),检测波长为299nm,流动相为pH6.8的乙腈-0.02mol/L磷酸缓冲溶液(70:30,V/V),流速为0.6mL/min,进样量20μL。结果:噻菌灵在0.10~90.0μg/mL范围内与峰面积成良好线性关系(r=0.9995),检测限为0.05μg/mL,噻菌灵的回收率为87.9%~102.6%,相对标准偏差为0.98%~2.79%。结论:该方法操作简便快速,可作为灯笼果中噻菌灵含量监测的控制方法。

Abstract: Purpose: A reversed-phase high performance liquid chromatographic method with PDA was used for the residue analysis of triabendazole in Peruvian ground cherry. Methods: The HPLC conditions were as follows: the column was Shim-pack VP-ODS 150 mm × 4.6 mm. CH3CN:0.02mol/L H3PO4 (pH 6.8) = 70:30 (V/V) as mobile phase, flow rate 0.6 mL /min, injection volume 20 μL and detection wavelength 299 nm. Results: Good linearity of triabendazole was obtained over the range of 0.10-90.0 μg/mL (r = 0.9995). The detection limits were 0.05 μg/mL for triabendazole. The average recoveries ranged from 87.9% to 102.6% with relative standard deviation of 0.98%-2.79%. Conclusions: The method is fast and simple for the residue detection and analysis of triabendazole in Peruvian ground cherry.
