A new sesquiterpene from endophytic fungus Aspergillus sp.
A fungal strain named YLF-14 was isolated from the leaf of Altingia yunnunensis. Based on the sequence at the internal transcribed spacer (ITS) region, the strain was identified as an Aspergillus sp.. A new sesquiterpene 5β,8aβ-dimethyl-3,4,4aβ,5,6,7,8,8a-octahydronaphthalene-1,2,5α-trimethanol (1) and a known compound 12-N-methylcyclo-(L-tryptophyl-L-phenylalanyl) (2) were isolated from the culture of this strain. Bioassay experiments showed that the two compounds had no obvious effect on the growth of tested bacteria and nematodes.
