摘要: 对海洋来源真菌Hansfordia sinuosae的化学成分进行研究,采用硅胶柱、Sephadex LH-20柱和半制备HPLC色谱分离纯化,运用1D NMR (1H NMR、13C NMR)、2D NMR (HMQC、1H-1H COSY、HMBC)及MS等现代波谱学方法并结合相关的文献,从中分离鉴定3个异香豆素类化合物,分别为:(E)-6,8-dihydroxy3-(prop-1-en-1-yl)-1-H-isochromen-1-one (1),(R)-6-hydroxymellein (2),3-methyl-6,8-dihydroxyisocoumarin (3)。其中,化合物1为新化合物,化合物3为首次在该种菌株中分离得到。

Abstract: Chemical constituents of fermentation broth of marine-derived fungus Hansfordia sinuosae were studied using column chromatography,semi-preparative HPLC,ODS column chromatography and Sephadex LH-20 column chromatography,respectively.Three isocoumarin compounds were obtained.Based on 1D NMR,2D NMR,high resolution MS and IR analyses,their structures were elucidated as (E)-6,8-dihydroxy-3-(prop-1-en-1-yl)-1-H-isochromen-1-one (1),(R)-6-hydroxymellein (2),3-methyl-6,8-dihydroxyisocoumarin (3).Compound 1 is a new compound,and compound 3 is isolated from this genus of fungus for the first time.
