The metabolic profile of T-2 toxin (T-2) and its modified form T-2-3-glucoside (T-2-3-Glc) remain unexplored in human samples. Therefore, the present study aimed to investigate the presence of T-2, T-2-3-Glc and their respective major metabolites in human urine samples ( 300) collected in South Italy through an ultra-high performance liquid chromatography (UHPLC) coupled to Q-Orbitrap-HRMS methodology. T-2 was quantified in 21% of samples at a mean concentration of 1.34 ng/mg Crea (range: 0.22-6.54 ng/mg Crea). Almost all the major T-2 metabolites previously characterized in vitro were tentatively found, remarking the occurrence of 3'-OH-T-2 (99.7%), T-2 triol (56%) and HT-2 (30%). Regarding T-2-3-Glc, a low prevalence of the parent mycotoxin (1%) and its metabolites were observed, with HT-2-3-Glc (17%) being the most prevalent compound, although hydroxylated products were also detected. Attending to the large number of testing positive for T-2 or its metabolites, this study found a frequent exposure in Italian population.
在人类样本中,T-2 毒素(T-2)及其修饰形式 T-2-3-葡萄糖苷(T-2-3-Glc)的代谢谱仍未得到探索。因此,本研究旨在通过超高效液相色谱(UHPLC)与 Q-Orbitrap-HRMS 方法,检测来自意大利南部的 300 个人类尿液样本中 T-2、T-2-3-Glc 及其各自主要代谢物的存在情况。在 21%的样本中定量检测到 T-2,其平均浓度为 1.34ng/mgCrea(范围:0.22-6.54ng/mgCrea)。几乎所有先前在体外表征的主要 T-2 代谢物都被推测发现,其中 3'-OH-T-2(99.7%)、T-2 三醇(56%)和 HT-2(30%)的含量较高。关于 T-2-3-Glc,母体真菌毒素(1%)及其代谢物的检出率较低,其中 HT-2-3-Glc(17%)是最常见的化合物,尽管也检测到了羟基化产物。鉴于大量样本中 T-2 或其代谢物呈阳性,本研究发现意大利人群中存在频繁的暴露情况。
