Morphology and phylogeny have been used to distinguish members of the plant pathogenic fungal genus Stemphylium. A third method for distinguishing species of fungi is by chemotaxonomy. The main goal of the present study was to investigate the chemical potential of Stemphylium via HPLC-UV-MS analysis, while also exploring the potential of chemotaxonomy as a robust identification method for Stemphylium. Several species were found to have species-specific metabolites, while other species were distinguishable by a broader metabolic profile rather than specific metabolites. Many previously described metabolites were found to be important for distinguishing species, while some unknown metabolites were also determined to have important roles in distinguishing species of Stemphylium. This study is the first of its kind to investigate the chemical potential of Stemphylium across the whole genus.
形态学和系统发育学已被用于区分植物病原真菌匍柄霉属的成员。区分真菌物种的第三种方法是化学分类学。本研究的主要目标是通过高效液相色谱-紫外-质谱分析来研究匍柄霉属的化学潜力，同时也探索化学分类学作为匍柄霉属可靠鉴定方法的潜力。发现几个物种具有物种特异性代谢产物，而其他物种则通过更广泛的代谢谱而非特定代谢产物来区分。许多先前描述的代谢产物被发现对区分物种很重要，同时一些未知代谢产物也被确定在区分匍柄霉属物种中具有重要作用。本研究是首次对整个匍柄霉属的化学潜力进行研究。
