中文摘要: |
采用硅胶、凝胶柱层析以及反相高效液相色谱等分离技术,从一株毛壳霉属真菌的固体发酵提取物中分离纯化了5个聚酮类化合物chaetomones A-E(1-5),其结构主要通过分析核磁共振数据确定。生物活性测试结果表明化合物5具有抗白色念珠菌Candida albicans(ATCC 10231)的活性,其IC50为20.0μmol/L。 |
英文摘要: |
Five new polyketides, chaetomones A-E (1-5), have been isolated from solid cultures of Chaetomium sp. by silica gel column chromatography (CC), Sephadex LH-20 CC and RP HPLC. The structures of these metabolites were determined mainly by analysis of their NMR spectroscopic data. Compound 5 displayed antifungal activity against Candida albicans (ATCC 10231) with an IC50 value of 20.0μmol/L. |
