摘要
Three new cyclohexenones (1-3, named sarcosones A-C) and two new isocoumarins (4 and 5), together with five known isocoumarins (6-10), were isolated from the solid cultures of an endophytic fungus Sarcosomataceae sp. NO.49-14-2-1. Their chemical structures were elucidated by analyses of HR-ESI-TOF-MS, H-1, C-13 NMR, H-1-H-1 COSY, HSQC, and HMBC spectra. Their absolute configurations were determined via modified Mosher's method and circular dichroism spectra method.
