Chemical examination of a marine sponge Spheciospongia sp. collected from South China Sea resulted in the isolation of five norisoprenoid derivatives (1-5), of which two new compounds were designated with trivial names of spheciospongones A (1) and B (2). Their structures were determined on the basis of extensive 1D and 2D NMR, and MS spectroscopic data analysis in association with circular dichroism. Norisoprenoids were found from the sponge genus Spheciospongia for the first time, and were suggested to be the chemical marks for chemical taxonomy.
对采自中国南海的一种海洋海绵Spheciospongia sp.进行化学分析，从中分离出5种降异戊二烯衍生物（1 - 5），其中两种新化合物被分别命名为海绵素A（1）和海绵素B（2）。通过广泛的一维和二维核磁共振以及质谱光谱数据分析，并结合圆二色性确定了它们的结构。首次从海绵属Spheciospongia中发现了降异戊二烯类化合物，并认为它们是化学分类学的化学标记。
