摘要: We developed a simple, sensitive and rapid analytical method for simultaneous quantification of spinetoram (XDE-175-L and XDE-175-J) residue in foods originating from plants (cucumber, cabbage, eggplant, pepper, bayberry, mango, rice, wheat, and codonopsis) or animals (eggs, milk, pork, and chicken). The method was validated by ultra-high performance liquid chromatography coupled to tandem mass spectrometry, run in the positive-ion mode with selected reaction monitoring. Briefly, the samples were extracted with acetonitrile and purified via dispersive solid-phase extraction with octadecylsilane, primary secondary amine, or graphitized carbon black, used either singly or in combination. The method provides good linearity (R-2 >= 0.9956) and outstanding performance (trueness and recovery percentages 80.1-111.3%; intra-day/inter-day precision of 1.2-9.7% and 3.9-12.9%). For all food matrices, the limit of quantification was 0.125 mu g kg(-1) for XDE-175-L and 0.375 mu g kg(-1) for XDE-175-J. We also validated the applicability of the method using 130 samples obtained from commercial sources, which revealed trace amounts of spinetoram in 28 of those samples. The data indicated that the method yields reproducible results and is sufficiently sensitive for the detecting trace amounts of spinetoram in plant- and animal-type foods.
