中文摘要：本研究开发了一种用QuEChERS提取结合超高效液相色谱串联质谱(UHPLC-(ESI)MS/MS)，同时检测植物基质饮料中11种霉菌毒素的方法。该多霉菌法用于分析以植物，如大豆、燕麦和大米为原料的饮料。本研究首次分析了植物性饮料，并在样品中发现了某些霉菌毒素如脱氧雪腐镰刀菌烯醇、黄曲霉毒素B1、B2、G1及G2、赭曲霉毒素A、T-2毒素及玉米赤霉烯酮，其中部分含量在0.1mug/L到19mug/L之间。
外文摘要：A method was developed for the simultaneous determination of 11 mycotoxins in plant-based beverage matrices, using a QuEChERS extraction followed by ultra-high performance liquid chromatography coupled to tandem mass spectrometry detection (UHPLC-(ESI)MS/MS). This multi-mycotoxin method was applied to analyse plant-based beverages such as soy, oat and rice. QuEChERS extraction was applied obtaining suitable extraction recoveries between 80 and 91%, and good repeatability and reproducibility values. Method Quantification Limits were between 0.05 mu g L-1 (for aflatoxin G(1) and aflatoxin B-1) and 15 mu g L-1 (for deoxynivalenol and fumonisin B-2). This is the first time that plant-based beverages have been analysed, and certain mycotoxins, such as deoxynivalenol, aflatoxin B-1, aflatoxin B-2, aflatoxin G(1), aflatoxin G(2), ochratoxin A, T-2 toxin and zearalenone, were found in the analysed samples, and some of them quantified between 0.1 mu g L-1 and 19 mu g L-1.
