中文摘要：以氢化硅胶为固定相通过液相色谱串联质谱分析所选的食品样品可以鉴定并量化常见的霉菌毒素，包括黄曲霉毒素B1、B2、G1、G2、赭曲霉毒素A及伏马菌素B1。研究发现大豆、玉米、水稻、小麦样品收获和储存的条件有利于真菌发展，且所有样品中的有毒污染物均超过了最大容许量。
外文摘要：Liquid chromatography with mass spectrometry analysis of selected food samples using silica hydride stationary phases allowed for the identification and quantification of common mycotoxins including aflatoxin B1, B2, G1, G2, ochratoxin A, and fumosinin B1. Phenyl and C18 columns showed relatively similar selectivity based on hydrophobicity but the phenyl phase provides an additional mechanism, π-π interaction. The most hydrophobic of the analyzed compounds was more strongly retained on the C18 column and also has fewer unsaturated sites, which limited the interaction with the phenyl phase. Bean, maize, rice, and wheat samples were harvested and stored under conditions conducive to fungal development, and all samples presented toxin contamination exceeding the maximum tolerable limits.
