Two new furanone derivatives, byssochlanones A-B (-) were purified from the endophytic fungus sp. isolated from the wetland plant, . Their structures were elucidated on the basis of extensive spectroscopic analyses. Compounds - represented typical furanone analogues which are not common in natural products. The absolute configuration of compounds - were identified through quantum-chemical electronic circular dichroism (ECD) calculation compared with their experimental CD. In addition, compounds - were tested for their cytotoxic activities against HCT-8 and Hela cancer cell lines, and compound showed moderate activity against HCT-8 cells with IC value of 21.3 M.
