In addition to several known sterols, a new C(29) marine sterol with a normal ergosterol nucleus but a modified side chain, named 26-nor-25-isopropyl-ergosta-5,7,22E-trien-3beta-ol, was isolated from the Jamaican sponge Agelas sceptrum. The structures were assigned by spectroscopic methods including high-resolution 2D NMR techniques.
除了几种已知的甾醇外，还从牙买加海绵Agelas sceptrum中分离出一种新的C(29)海洋甾醇，其具有正常的麦角甾醇核但侧链经过修饰，命名为26-降-25-异丙基-麦角甾-5,7,22E-三烯-3β-醇。通过包括高分辨率二维核磁共振技术在内的光谱方法确定了其结构。
