Abstract:
We have carried out the investigation on a sponge-derived fungus,which was identified as Emericella variecolor from the south sea of China. Two new chemical constituents,(+)-2-acetyl-dihydroterrein (1) and (+)-3-acetyl-dihydroterrein (2),with four known compounds,anditomin (3),andilesin A (4),andilesin C (5) and andilesin B (6),were isolated from this fungus by column chromatography over silica gel, Sephadex LH-20, and ODS. The structures of 1 and 2 were elucidated by spectroscopic methods including NMR,HR-ESI-MS,and CD.
