摘要

植物毒素是植物合成的次生代谢产物，是目前公认的一类新的环境微污染物。在陆地和水生环境中仅发现和报告了数量有限的植物毒素，部分原因是分析方面的挑战。本文介绍了一种强大、可靠和高效的方法，即来源支持的可疑筛选(4S)，用于从植物来源到下游环境区室的植物毒素的高通量分析。建立了超高效液相色谱-电喷雾电离-四极杆飞行时间质谱(UHPLC-ESI-QTOF-MS)分析平台，研究了最佳样品制备和色谱条件，并提出了新的可疑分子筛选方案。

Suspect Screening of Lupin-Produced Phytotoxins in Environmental Samples

Phytotoxins, secondary metabolites synthesized by plants, are now recognized as a new category of environmental micropollutants. Only a limited number of phytotoxins have been detected and reported in terrestrial and aquatic environments, partially due to analytical challenges. In this article, a robust, reliable, and efficient approach, namely Source Supported Suspect Screening (4S), is introduced for high-throughput analysis of phytotoxins from their plant origin to the downstream environmental compartments. The approach was established on an ultrahigh-performance liquid chromatography–electrospray ionization–quadrupole‑time‑of‑flight-mass spectrometry (UHPLC–ESI–QTOF-MS) analytical platform where optimal sample preparation and chromatographic conditions were investigated and a new suspect screening protocol was suggested.
