在前文中提到从一种新种软珊瑚(Sinularia Fibrilla sp.nov.)中分离出一种无色透明片状晶体(S304),含量约0.15%,熔点135.0—136.0℃[乙醇],分子式为C_(30)H_(50)O,是一种甾族化合物.经波谱和混合熔点鉴定为:23—乙基—24—亚甲基—△~5—胆甾烯—3β—醇(sipalosterol—A).本文报导鉴定S_(304)数据.
It is mentioned in the foregoing that a colorless and transparent lamellar crystal (S304) is isolated from a new species of soft coral (Sinularia Fibrilla sp. Nov.) In an amount of about 0.15% and has a melting point of 135.0-136.0 ° C [ethanol] Is C_ (30) H_ (50) O, which is a kind of steroid.It has been identified by spectroscopy and mixed melting point that: 23-Ethyl-24-methylene- △ 5-cholestene- -A). This paper reports the identification of S_ (304) data.
