| 中文摘要: |
| 目的 对深海沉积物来源真菌Aspergillus insulicola中的化学成分进行研究。方法 采用正反向硅胶柱色谱、高效液相色谱等方法对其大米发酵产物进行分离提纯；通过质谱、核磁共振等波谱学方法并结合文献数据鉴定其结构。结果 从海洋真菌A. insulicola大米发酵产物的乙酸乙酯提取物中共分离鉴定了9个化合物,其结构分别为：aspermicrone C(1)、aspermicrone B(2)、epicolactone(3)、F14945-C(4)、6,7-dihydroxy-5-methoxy-4-methylisobenzofuran-1(3H)-one(5)、5,6-dihydroxy-7- methoxy-4-methylisobenzo- furan-1(3H)-one(6)、3-methoxyepicoccone(7)、3,4-dihydroxyphenylacetic acid methyl ester(8)和glycerol-1- monooleate(9)。结论 化合物5为新的天然产物,其余化合物均为已知化合物。生物活性测试结果显示化合物1和2对火龙果黑斑病菌有一定的抑制作用。 |

| Objective To study the chemical constituents of the marine-derived fungus Aspergillus insulicola which was isolated from deep-sea sediment. Methods All compounds were separated and purified by silica gel column chromatography and high-performance liquid chromatography, and the structures of isolated compounds were identified by mass spectrometry and nuclear magnetic resonance combined with literature data. Results Nine compounds were isolated from ethyl acetate extract of marine-derived fungus A. insulicola, and their structures were identified as aspermicrone C (1), aspermicrone B (2), epicolactone (3), F14945-C (4), 6,7-dihydroxy-5-methoxy-4-methylisobenzofuran-1(3H)-one (5), 5,6-dihydroxy-7-methoxy-4-met |
