摘要: 采用硅胶柱色谱,半制备高压液相色谱(HPLC),ODS柱色谱以及Sephadex LH-20凝胶柱色谱等多种方法从海洋真菌灰黄青霉Penicillium griseofulvum发酵液的乙酸乙酯萃取物中分离纯化得到3个化合物,采用1D NMR(1H NMR、13C NMR、DEPT)、2D NMR(HMBC、HMQC、1H-1H COSY)及MS等光谱学方法分析及参考相应的文献,确定它们的结构分别为:2-(6-羟基-5,7-二甲基苯并呋喃酮-4-基)乙醛(1)、对苯二甲酸二(2-乙基)己酯(2)和己二酸二乙基己酯(3),其中化合物1为新化合物。

Abstract: Three chemical constituents were separated and purified from marine-derived fungus Penicillium griseofulvum by silica gel column chromatography,semipreparative HPLC,ODS column chromatography and Sephadex LH-20 column chromatography.On the basis of spectral data (1D NMR,2D NMR and high resolution MS),their structures were elucidated as 2-(6-hydroxy-5,7-dimethylbenzofuranone-4-yl)acetaldehyde (1),terephthalic acid bis(2-ethyl-hexyl) ester (2) and bis(2ethylhexyl) adipate (3).Compound 1 was a new compound.

Key words: marine fungus, Penicillium griseofulvum, secondary metabolites, NMR
