Nineteen compounds mainly including pyrrole‐containing alkaloids and phytosterols were isolated from the EtOH extract of the fermented mycelia of Xylaria nigripes, a precious medicinal fungus known as Wuling Shen in Chinese. On the basis of spectroscopic methods, the structures of the new naturally occurring compounds were determined to be (4S)‐3,4‐dihydro‐4‐(4‐hydroxybenzyl)‐3‐oxo‐1H‐pyrrolo[2,1‐...
Two new [named xylapyrrosides A (1) and B (2)] along with two known [pollenopyrrosides A (3) and B (=acortatarin A, 4)] naturally occurring spirocyclic pyrrole alkaloids were isolated and identified as minor components from the EtOH extract of the dried mycelia of the edible medicinal fungus Xylaria nigripes. Their structures were established by a combination of interpretation of spectroscopic data...
