This work reports the optimization of a method using Molecularly Imprinted Polymers (MIPs) for the simultaneous determination of zearalenone and alternariol mycotoxins. The method was optimized using a chemometric approach where in the optimized conditions, the cartridges with a mixture (50:50, w/w) of both MIPs, were loaded with 30 mL of sample, washed with 2 mL of ACN/water (20/80, v/v) and eluted with 2.5 mL of trifluoroacetic acid/MeOH (3/97, v/v). The extracts were analyzed by HPLC coupled to a fluorescence detector (FLD). The optimized method has been applied and validated to the analysis of the mycotoxins in maize, sunflower and olive oils samples with a limit of detection of 5 and 2 µg kg-1, respectively. Recoveries were in the range of 94% to 108% (RSD < 6%) for zearalenone and 92% to 113% (RSD < 5%) for alternariol. The results were confirmed by HPLC-MS/MS.

使用混合分子印迹聚合物微球同时测定油样中的玉米赤霉烯酮和交链孢酚霉菌毒素

这项工作报告了一种使用分子印迹聚合物 (MIP) 同时测定玉米赤霉烯酮和交链孢霉毒素的方法的优化。该方法使用化学计量学方法进行了优化,在优化条件下,将两种 MIP 的混合物 (50:50,w/w) 装入 30 mL 样品的小柱,用 2 mL 乙腈/水 (20 /80, v/v) 并用 2.5 mL 三氟乙酸/MeOH (3/97, v/v) 洗脱。通过与荧光检测器 (FLD) 耦合的 HPLC 分析提取物。优化后的方法已应用于玉米、向日葵和橄榄油样品中霉菌毒素的分析并得到验证,检测限为 5 和 2 µg kg -1, 分别。玉米赤霉烯酮的回收率在 94% 到 108%(RSD < 6%)之间,交链孢酚的回收率在 92% 到 113%(RSD < 5%)之间。结果通过 HPLC-MS/MS 确认。
