摘要: 对海绵共附生真菌FWZ0415进行固体发酵培养,并对其发酵培养物的次级代谢产物进行分离纯化和结构鉴定等方面的研究。运用常压硅胶柱层析、葡聚糖凝胶柱(Sephadex LH-20)和半制备高效液相色谱(HPLC)等手段,从该菌株固体发酵培养物的提取物中分离纯化得到两个化合物,并运用核磁共振1H NMR、13C NMR等手段鉴定这两个化合物的结构为violaceol-I和violaceol-II。测试这两个化合物对肿瘤细胞系K252、MCF-7、SGC7901的细胞毒性,violaceol-I未见显著的细胞毒性(IC50>30 μmol),violaceol-II对3株肿瘤细胞系的IC50分别为16.7、16.3、15.8 μmol。

Abstract: Sponge epiphytic fungi FWZ0415 was cultured in solid state fermentation,and its secondary metabolites were isolated,purified and identified. Using silica gel column chromatography,Sephadex column(Sephadex LH-20) and the preparation of semi preparative high performance liquid chromatography(HPLC) methodtwo compounds were purified,and then identified as violaceol-I and violaceol-II by nuclear magnetic resonance 1H-NMR and 13C-NMR. The cytotoxicity of two compounds to K252,MCF-7 and SGC7901 were tested,violaceol-I was not significantly cytotoxicity(IC50>30 μmol). The IC50 of violaceol-II to three tumor cell lines were 16.7,16.3,15.8 μmol,respectively.

Key words: spongye epiphytic fungi, secondary metabolites, isolation and purification, structural identification, antitumor activity
