Two new meroterpenoids, tricycloalternarenes X and Y, together with one known meroterpenoid, tricycloalternarene I, were isolated from the fungus Alternaria sp. JJY-32. The structures including absolute configurations were established by the comprehensive spectroscopic data, electronic circular dichroism (ECD) spectral analyses, and biosynthesis consideration. Tricycloalternarene X showed cytotoxicity against the HL-60 and HO8910 cells with IC values of 7.54 and 20.32 μm.
两种新的倍半萜类化合物，三环交替烯 X 和 Y，以及一种已知的倍半萜类化合物，三环交替烯 I，从真菌交替曲霉菌 JJY-32 中分离得到。通过综合光谱数据、电子圆二色性（ECD）光谱分析和生物合成考虑，确定了结构包括绝对构型。三环交替烯 X 对 HL-60 和 HO8910 细胞具有细胞毒性，IC 值分别为 7.54 和 20.32 μm。
