Two new anthraquinone-steroids, evanthrasterol A and B (1 and 2), and a new meroterpenoid, emericellic acid (3), together with six known compounds (4-9) were isolated from an endophytic fungus, Emericella variecolor. Their structures were determined by spectroscopic analysis (1D and 2D NMR, HRESIMS and FTIR). Herein emericellic acid (3) is a new skeleton of meroterpenoid with carboxylic functional group at C-9' and this is the first report on isolation of anthraquinone-steroids from E. variecolor.
从内生真菌杂色埃默森菌（Emericella variecolor）中分离出两种新的蒽醌-甾体化合物，埃文甾醇A和B（1和2），以及一种新的杂萜类化合物，埃默里酸（3），同时还分离出六种已知化合物（4-9）。通过光谱分析（一维和二维核磁共振、高分辨电喷雾电离质谱和傅里叶变换红外光谱）确定了它们的结构。在此，埃默里酸（3）是一种新的杂萜类骨架，在C-9'处带有羧基官能团，这是首次从杂色埃默森菌中分离出蒽醌-甾体化合物的报道。
