A New Compound Along With Seven Known Compounds from an Endophytic Fungus Aspergillus sp . HS-05

Investigation of EtOAc extract from the fermentat ion broth of the endophytic fungus Asperilligus sp. HS-05 led to the isolation of a new compound ( 1) of spiro moiety named aspergispiroketal and seven known compounds ( 2-8). Their structures were elucidated mainly by NMR a nd HR-TOF-MS, as well as on comparison with the reported data. The absolute configuration of 1 was defined by comparison of quantum chemical TDDFT calculated and experimental ECD spectra.
