Abstract
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, 1H, 13C NMR, 1H–1H COSY, HSQC, and HMBC spectra. Their absolute configurations were determined via modified Mosher's method and circular dichroism spectra method.
