Two new meroterpenes from endophytic fungus A1 of Scyphiphora hydrophyllacea

摘要

Two new meroterpenes, guignardone D (1) and guignardone E (2), were isolated from endophytic fungus A1 of Scyphiphora hydrophyllacea Gaertn. F. Their structures were established based on spectroscopic methods including 1D and 2D NMR (HMQC, 1H- 1H COSY, HMBC, and ROESY).
