从一种新种软珊瑚(Sinularia Siplaosa sp.nov.)中分离出两种新的甾醇,命名为Sipalosterol A 及Sipalosterol B.本文主要报导:通过波谱分析及化学转变等方法测定了SipalosterolA 的化学结构为23-乙基-24-亚甲基-△~5-胆甾烯-3-β-醇.
Two new sterols, named Sipalosterol A and Sipalosterol B, were isolated from a new species of Sinularia Siplaosa sp.nov. The paper reports the chemical structure of Sipalosterol A by spectroscopic analysis and chemical transformation Is 23-ethyl-24-methylene-Δ5-cholesten-3-β-ol.
