Talaromycones A (1) and B (2), new xanthenediones, were isolated from the cultures of Talaromyces sp. ECN211, an endophytic fungus, along with α-diversonolic ester (3), aspergillusone B (4), glauconic acid (5), and rosellisin (6). The planar structures of 1 and 2 were elucidated by extensive spectroscopic analyses. Furthermore, the absolute configurations of 1–4 were determined by single-crystal X-ray diffraction and electronic circular dichroism spectroscopy (ECD). In addition, the crystallographic data for 5 were updated for the first time in over 50 years.

内生Talaromyces sp。的talalomycones A和B，α-二磺酸酯和曲霉酮B的绝对构型。ECN211

Talaromycones A（1）和B（2），新的xanthenediones，是从Talaromyces sp。的培养物中分离出来的。ECN211，一种内生真菌，以及α-双磺酸酯（3），曲霉酮B（4），葡糖二酸（5）和玫瑰果素（6）。通过广泛的光谱分析阐明了1和2的平面结构。此外，的绝对构型1 - 4通过单晶X射线衍射和电子圆二色光谱（ECD）来确定。另外，晶体学数据为5 是50多年来第一次更新。
