Fungi are an important source of natural products found in a variety of plant species. A wide range of methods for the detection of metabolites present in fungi have been reported in the literature. The search for methodologies that allow the rapid detection of compounds present in crude extracts is crucial to enable the metabolite annotation doing a qualitative analysis of the complex matrix. Mass spectrometry is an important ally when it comes to in silico detection of previously reported metabolites. In this work, the ethyl acetate extract of Fusarium solani was analyzed by gas chromatography coupled to mass spectrometry (GC/MS) after derivatization process. The ethyl acetate extract was also investigated by liquid chromatography coupled with high-resolution tandem mass spectrometry assisted by the UNIFI software system. A library containing previously reported metabolites from the Fusarium genus was added to the UNIFI platform. Simultaneously, the extract was analyzed through anticholinesterase and antifungal assays. The analysis of the derivatized extract by GC/MS led to the putative identification of five metabolites, and the investigation using Ultra-High Performance Liquid Chromatography - Quadrupole Time-of-Flight Mass Spectrometry (UPLC-QTOF) analysis in data-independent acquisition mode (mass spectrometry) led to the annotation of 15 compounds present in the built-in Fusarium library added to the UNIFI system. The Fusarium solani extract showed potential anticholinesterase and in vitro antifungal activity supported by the detection of bioactive metabolites.

在 UNIFI 信息系统的协助下,使用 GC/MS 和 UPLC-QTOF/MSE 技术快速定性分析 Fusarium solani(一种源自番泻叶的根际真菌)中存在的代谢物

真菌是多种植物物种中天然产物的重要来源。文献中报道了多种检测真菌中存在的代谢物的方法。寻找能够快速检测粗提取物中存在的化合物的方法对于使代谢物注释能够对复杂基质进行定性分析至关重要。当涉及到先前报告的代谢物的计算机检测时,质谱法是一个重要的盟友。在这项工作中,在衍生化过程中,用气相色谱-质谱联用 (GC/MS) 分析了茄病镰刀菌的乙酸乙酯提取物。在 UNIFI 软件系统的辅助下,还通过液相色谱法和高分辨率串联质谱法对乙酸乙酯提取物进行了研究。包含先前报道的镰刀菌属代谢物的库已添加到 UNIFI 平台。同时,通过抗胆碱酯酶和抗真菌试验分析提取物。GC/MS 对衍生提取物的分析导致对五种代谢物的推定鉴定,以及使用超高效液相色谱 - 四极杆飞行时间质谱 (UPLC-QTOF) 分析在数据独立采集模式下进行的调查(质谱)导致对 UNIFI 系统中内置镰刀菌库中存在的 15 种化合物进行注释。Fusarium solani 提取物显示出潜在的抗胆碱酯酶和体外抗真菌活性,并得到了生物活性代谢物检测的支持。提取物通过抗胆碱酯酶和抗真菌试验进行分析。GC/MS 对衍生提取物的分析导致对五种代谢物的推定鉴定,以及使用超高效液相色谱 - 四极杆飞行时间质谱 (UPLC-QTOF) 分析在数据独立采集模式下进行的调查(质谱)导致对 UNIFI 系统中内置镰刀菌库中存在的 15 种化合物进行注释。Fusarium solani 提取物显示出潜在的抗胆碱酯酶和体外抗真菌活性,并得到了生物活性代谢物检测的支持。提取物通过抗胆碱酯酶和抗真菌试验进行分析。GC/MS 对衍生提取物的分析导致对五种代谢物的推定鉴定,以及使用超高效液相色谱 - 四极杆飞行时间质谱 (UPLC-QTOF) 分析在数据独立采集模式下进行的调查(质谱)导致对 UNIFI 系统中内置镰刀菌库中存在的 15 种化合物进行注释。Fusarium solani 提取物显示出潜在的抗胆碱酯酶和体外抗真菌活性,并得到了生物活性代谢物检测的支持。以及使用超高效液相色谱 - 四极杆飞行时间质谱 (UPLC-QTOF) 分析在数据独立采集模式(质谱)下进行的调查导致对内置镰刀菌库中存在的 15 种化合物进行注释加入到 UNIFI 系统中。Fusarium solani 提取物显示出潜在的抗胆碱酯酶和体外抗真菌活性,并得到了生物活性代谢物检测的支持。以及使用超高效液相色谱 - 四极杆飞行时间质谱 (UPLC-QTOF) 分析在数据独立采集模式(质谱)下进行的调查导致对内置镰刀菌库中存在的 15 种化合物进行注释加入到 UNIFI 系统中。Fusarium solani 提取物显示出潜在的抗胆碱酯酶和体外抗真菌活性,并得到了生物活性代谢物检测的支持。
