Two new sesquiterpenes produced by the endophytic fungus <i>Aspergillus fumigatus</i> from <i>Ligusticum wallichii</i>

Two previously undescribed sesquiterpenes along with nine known compounds were isolated from the fermentation broth of Aspergillus fumigatus, an endophyte of Ligusticum wallichii. Their structures were elucidated through extensive spectroscopic analysis combined with quantum chemical ECD calculations. Two new compounds exhibited moderate growth inhibition against MV4-11 and MDA-MB-231 cell lines.
