从海绵SpongiazimoccasubspeciesirregulariaLemdenfeld中分离到2个新的海绵烷型二萜(2),(3),依次命名为zimoclatoneB和zimoclactoeC。应用1D和2DNMR和X射线单晶衍射分析方法测定了这两个新二萜的化学结构及相对构型。

Two new spongian diterpenes, named zimoclactone B (2) and zimoclatone C (3) were isolated from the marine sponge Spongia zimocca subspecies irregularia. Their chemical structures and relative configurations were determined mainly by 1D and 2D NMR experiments as well as X-ray diffraction analysis.
