从西太平洋深海沉积物中分离出八种化合物，包括两种bisorbicillinoids（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详细的NMR光谱数据分析确定。所有化合物均从A. alternatum第一次Bisorbicillinoids 1和Bisorbicillinoids 2可能是区分A. alternatum和A. Citrinum与其他枝顶孢属物种。神经酰胺3和4是A的指示化合物。3个甾体化合物5、6和7可能具有系统学意义，可用于区分A. alternatum与其他枝顶孢属物种。
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.
