Sesquiterpenes Isolated from Aspergillus fumigatus, an Endophytic Fungus from Ligusticum wallichii

Four sesquiterpenes, including a previously undescribed one, were isolated from the fermentation broth of an endophytic fungus Aspergillus fumigatus, which was obtained from the root of Ligusticum wallichii. Their structures were elucidated through extensive spectroscopic analyses, and the absolute configurations of 1 and 3 were elucidated through NOESY analyses combined with the calculated ECD spectra.
