| 目的 对西沙掘海绵Dysidea sp.进行化学成分研究；方法 运用正相硅胶柱色谱、反相ODS柱色谱、凝胶Sephadex LH-20柱色谱以及高效液相色谱(HPLC)等多种分离手段对西沙掘海绵Dysidea sp.化学成分进行分离纯化；并通过理化性质、波谱学数据等结构信息鉴定其化合物的结构。结果发现：从西沙掘海绵Dysidea sp.中分离鉴定了8个化合物，分别为dictyoceratin C（1）、dactyloquinone B（2）、aminoquinone（3）、dictyoceratin A（4）、dactyloquinone D（5）、dactyloquinone E（6）、(1R*,2E,4R*,7E,10S*,11S*,12R*)-10,18-diacetoxydolabella-2,7-dien-6-one（7）和?,?-unsaturated ester（8），结论 化合物1?6和8均为首次从该属海绵中分离得到。 |

| Abstract: Objective: To study the chemical compositions of the marine sponge Dysidea sp. collected from the Xisha Islands. Method: The chemical constituents of the marine sponge Dysidea sp. collected from the Xisha Islands in South China Sea were chemically investigated. Normal-phase Silica gel, Sephadex LH-20, HPLC, and other chromatographic methods were employed to isolate and purify eight compounds from the marine sponge.Their chemical structures were identified as dictyoceratinC (1), dactyloquinone B (2), aminoquinone (3), dictyoceratin A (4), dactyloquinone D (5), dactyloquinone E (6), (1R*,2E,4R*,7E,10S*,11S*,12R*)-10,18-diacetoxydolabella-2,7-dien-6-one (7), and ?,?-unsaturated ester (8),by spectroscopic analysis and comparison with the literature data. Conclusion Compounds 1?6 and 8 were isolated from the genus of Dysidea for the first time. |
