南海海绵Iotrochota ridley化学成分的研究(-)

A Study on the Chemical Constituents of the Marine Sponge Iotrochota ridley from South China Sea (Ⅰ)

从中国南海海绵Iotrochotaridley中分离到一种长链甘油醚，其结构经IR，MS，1HNMR，13CNMR，1H－1HCOSY确定为3-十八烷氧基-1，2-丙二醇（鲨肝醇）（Ⅰ）。本文是首次报道该种属海绵的化学成分。

A known long - chain aliphatic alcohol glycerol ether crmpound C21 H44 O3 has been isolatedfrom the marine sponge Introchota ridley collected from South China Sea . Its structure has beenidentified by the data of IR,MS,1H NMR,13C NMR and 2D1H - 1H COSY as 3 - octadecyloxy -1. 2 - PIDPanediol(baty alcohol), It is first reported about the chemical constituents of the marinesponge Introchota ridley of South Chaina Sea .
