| 摘 要： | 文章旨在研究南海冷泉来源真菌Talaromyces helicus SCSIO41311中聚酮类次生代谢产物。主要采用正相硅胶柱层析、反相硅胶柱层析、Sephadex LH-20、高效液相色谱(high performance liquid chromatography, HPLC)及薄层色谱(thin layer chromatography, TLC)等多种方法进行分离纯化;通过核磁共振波谱(nuclear magnetic resonance, NMR)、质谱(mass spectrometry,MS)等现代波谱分析方法及理化性质进行结构鉴定。从中分离得到7个聚酮类化合物,分别为:desmethylsulochrin (1)、sulochrin (2)、monomethylsulochrin (3)、circinophoric acid (4)、dimethyl 2,3-dimethylosoate(5)、endocrocin (6)和1-methyl emodin (7)。所有化合物均为首次从深海冷泉微生物中得到,其中化合物1为首次报道其核磁数据。

| Abstract: | In this study, we aim to investigate the secondary metabolites of polyketides from the South China Sea cold-seep-derived Talaromyces helicus SCSIO41311. The polyketides were isolated by normal phase silica gel column chromatography, reverse phase silica gel column chromatography, Sephadex LH-20, high-performance liquid chromatography (HPLC) and thin layer chromatography (TLC). The structures of compounds were identified by nuclear magnetic resonance spectrum (NMR), mass spectrometry (MS) and literature analysis. Seven polyketides were obtained and elucidated as follows: desmethylsulochrin (1), sulochrin (2), monomethylsulochrin (3), circinophoric acid (4), dimethyl 2,3-dimethylosoate (5), endocrocin (6) and 1-methyl emodin (7). All compounds were obtained for the first time from deep sea cold-seep. NMR data of 1 was firstly reported. |
