Dihydroberkleasmin A (1), a new ester-substituted sesquiterpenoid related to the eremophilane class, together with the known compound berkleasmin C (2), were isolated from the fermentation broth of the plant endophytic fungus Pestalotiopsis photiniae. The structure of dihydroberkleasmin A (1) was elucidated by extensive spectroscopic analysis. The stereochemistry was assigned by comparison of the NMR spectroscopic data with those of berkleasmin A.
二氢柏克利阿斯明 A（1），一种新的酯取代的倍半萜烯类化合物，与埃雷莫菲兰类有关，与已知化合物柏克利阿斯明 C（2）一起从植物内生真菌拟盘多毛孢发酵液中分离得到。通过广泛的光谱分析阐明了二氢柏克利阿斯明 A（1）的结构。通过与柏克利阿斯明 A 的 NMR 光谱数据进行比较，确定了其立体化学。
