【摘要】 <正> 海绵是目前海洋天然产物研究中最吸引人的海洋生物之一,海绵中含有丰富的结构新颖的次生代谢产物,它们大多数具有显著的生理活性,我们已报道了从海绵Phacellia fusca schmidt中分离及鉴定了3种生物碱,本文报道海绵P. fusca schmidt中A-降甾醇的分离和鉴更多还原

【Abstract】 Ten A-nor sterols (1-10), isolated from the marine sponge Phacellia fusca schmidtcollected from the South China Sea, were identified on the basis of the data of GC-MS and some other spectro-metric methods. These sterols are known but were found for the first time in the marine sponge P. fusca schinidt. The finding of the class of A-nor-sterols is of considerable value for chemotaxonomy of the Axinellidae family sponge.更多还原
