A new xanthone glycoside, sporormielloside (1), was isolated from an EtOAc extract of an endolichenic fungal strain Sporormiella irregularis (No. 71-11-4-1), along with two known xanthones (2, 3). Their structures were determined by detailed spectroscopic analysis (IR, MS, and 1D- and 2D-NMR), a chemical method, and a comparison of NMR data with closely related compounds previously reported. According
一种新的呫吨酮糖苷,sporormielloside (1),是从内源性真菌菌株 Sporormiella normis (No. 71-11-4-1) 的 EtOAc 提取物中分离出来的,以及两种已知的呫吨酮 (2, 3)。它们的结构是通过详细的光谱分析(IR、MS 和 1D-和 2D-NMR)、化学方法以及 NMR 数据与之前报道的密切相关化合物的比较确定的。根据分离化合物的结构,推断其合理的生物合成途径。
