从螳蛄相关真菌Aspergillus versicolor GH-2中分离得到5个新戊基二苯醚（1-5）、5个已知二苯醚（6-10）、3个口山酮（11-13）和3个蒽醌衍生物（14-16）。利用光谱学方法对其结构进行了分析。用改进的Mosher酯法确定了1的（2”S）绝对构型。已知化合物9和12对临床病原菌化脓性链球菌的MIC值分别为2.5和5.0 μ g/mL。(C) 2015 Elsevier Ltd.版权所有。
Five new prenylated diphenyl ethers (1-5), five known ones (6-10), and three xanthones (11-13), together with three anthraquinone derivatives (14-16), were obtained from the mantis-associated fungus Aspergillus versicolor GH-2. Their structures were elucidated on the basis of spectroscopic methods. The (2 '' S) absolute configuration of 1 was assigned by using the modified Mosher ester method. The known compounds 9 and 12 exhibited antibacterial activity against the clinical strain Streptococcus pyogenes with the MIC values of 2.5 and 5.0 mu g/mL, respectively. (C) 2015 Elsevier Ltd.
