抄録

A new butyrolactone, 7″-hydroxybutyrolactone III (1) and three new cycloheptanetriones, terretrione A–C (24), together with five known compounds, butyrolactone I, cyclo(Leu-Pro), cyclo(Val-Pro), cyclo(Ile-Pro), cyclo(Phe-Pro), were isolated from mangrove-associated marine fungus Aspergillus terreus. The structures of these compounds were elucidated on the basis of physical data analysis (NMR, high resolution-electrospray ionization (HR-ESI)-MS), especially by 2D-NMR techniques. These compounds showed weak cytotoxicity in vitro against HCT-8, Bel-7402, BGC-823, A2780 cell lines.
