Three new trihydroxytetralones (1, 2 and 3) have been isolated from the culture broth of P.diversum var. aureum together with three known naphthalenones (sclerone, isosclerone and juglone). The structure of 1 was determined on the basis of its chemical properties and spectroscopic analyses of the monomethyl ether (4) and dimethyl ether (5).
从 P.diversum var. aureum 的培养液中分离出了三种新的三羟基四氢萘酮(1、2 和 3)以及三种已知的萘酮(sclerone、isosclerone 和 juglone)。1 的结构是根据其化学特性以及单甲醚(4)和二甲醚(5)的光谱分析确定的。
