摘要
自帕劳群岛的3株9F系列海洋真菌中分离得到4个化合物,采用MS,NMR等光谱技术,确定结构分别为trans-dehydrocurvularin(1),terrein(2),paxilline(3)和citreopyrone(4),其对稻瘟霉P2b菌株的最小抑制浓度分别为:10,100,1.56,3.12μg/mL。其中化合物1是首次从海洋真菌中分离得到。
Four known metabolites have been isolated from the culture extracts of three 9F series marine fungi derived from Palau Islands. Their structures have been identified by spectral methods as trans-dehydrocurvularin （1）,terrein（2）,paxilline （3） and citreopyrone（4）. The MIC of 1-4 against Pyricularia oryzae P-2b were 10,100,1.56,3.12μg/mL. Compounds 1 were obtained from the cultures of marine fungi for the first time.
