A phytochemical investigation on Acremonium alternatum from the deep-sea sediment of the Western Pacific Ocean led to the isolation of eight compounds, including two bisorbicillinoids (1 and 2), two ceramides (3 and 4), and four steroids (5–8). The structures of the isolates were established mainly by detailed analysis of NMR spectroscopic data. All compounds were isolated from A. alternatum for the first time. The bisorbicillinoids 1 and 2 might be chemotaxonomic markers to differentiate A. alternatum and A. citrinum from other Acremonium species. The ceramides 3 and 4 are indicative compounds of A. alternatum, while three steroids 5, 6 and 7 could be of systematic interest to distinguish A. alternatum from other Acremonium species.

对来自西太平洋深海沉积物的Acremonium alternatum的植物化学研究导致分离出八种化合物，包括两种双山梨醇（ 1和2）、两种神经酰胺（3和4）和四种类固醇（5-8） . 分离物的结构主要通过核磁共振光谱数据的详细分析来确定。所有化合物均为首次从A. alternatum中分离得到。双山梨醇1和2可能是区分A. alternatum和A 的化学分类标记。来自其他顶头孢属物种的柑橘。神经酰胺3和4是A. alternatum的指示性化合物，而三种类固醇5、6和7可能具有系统意义，可将A. alternatum与其他顶头孢属植物区分开来。
