Two new phenolic glucosides from marine-derived fungus Aspergillus sp.

Two new phenolic glucosides, including a new O -glycoside ( 1 ) and a new C -glycoside ( 2 ), were isolated from a marine-derived fungus Aspergillus sp. The structures of new compounds were elucidated through interpretations of spectroscopic evidence and high-resolution electrospray ionization mass spectrometry. The hexose unit of 1 was identified as β -D-glucose by comparison with an authentic sample via HPLC after acid hydrolysis and derivatization. All compounds were evaluated for their ability to inhibit LPS-induced NO production in RAW264.7 macrophages, but none of them displayed significant activity.
