Abstract Three perylenequinones, the methylated 12-epi-stemphytriol (1), dihydroalterperylenol (2), and alterperylenol (3), were isolated from cultures of Curvularia lunata (LBQM-04) on malt extract broth. All these compounds were obtained from this particular fungus for the first time. Structures of compounds were determined based on MS and NMR spectra, as well as by comparison with the literature reports. The isolation of these phytotoxic reduced perylenequinones from the Curvularia genus suggested that they may occur in any anamorphic fungi belonging to the Pleosporaceae family.

月桂弯孢中的苝醌

摘要 三种苝醌，甲基化的 12-epi-stemphytriol (1)、dihydroalterperylenol (2) 和 alterperylenol (3)，是从新月弯孢菌 (LBQM-04) 的麦芽提取肉汤培养物中分离出来的。所有这些化合物都是首次从这种特殊真菌中获得。化合物的结构是基于MS和NMR光谱以及通过与文献报道的比较来确定的。从弯孢属中分离出这些植物毒性降低的苝醌表明它们可能存在于任何属于 Pleosporaceae 科的变形真菌中。
