摘要：

A new natural product named 6,8,1'-tri-O-methyl averantin has been isolated together with five known anthraquinones 1'-O-methyl averantin(2), 6,8-di-O-methyl averufin (3) averufin (4), versicolorin C (5) and 6,8-di-O-methyl averufanin (6) from a mangrove endophytic fungus ZSUH-36 collected from the South China Sea. NMR techniques including COSY, HMQC, and HMBC were used to elucidate the structures of these compounds. We report the unambiguous assignments of the H-1 and C-13 NMR spectra of the new compound 6,8,1'-tri-O-methyl averantin(l). Copyright (c) 2008 John Wiley & Sons, Ltd.
