Özet: Chemical examination of a fraction of the EtOAc extract of a marine-derived fungus Aspergillus sp. YPGA8 resulted in the isolation of two new compounds, namely aspertriols A-B (1-2). Compounds 1-2 possess an identical 2,3,4-trihydroxybutoxy moiety, which is rarely found in natural products. Their structures were determined by extensive analyses of spectroscopic data (1D and 2D NMR, HRESIMS). The bioassay study revealed that compounds 1 and 2 were inactive toward a-glucosidase.
