A new natural product named 6,8,1′‐tri‐ O ‐methyl averantin(1) 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 1 H and 13 C NMR spectra of the new compound 6,8,1′‐tri‐ O ‐methyl averantin(1). Copyright © 2008 John Wiley & Sons, Ltd.
