暗棕羊海绵Ircinia fusca Carter 1880.化学成分的研究

摘要

首次对暗棕羊海绵Ircinia fusca Carter 1880.化学成分进行研究，从该属海绵中分离得到4个单体化合物，经过波谱等手段鉴别为胸腺嘧啶、尿嘧啶、次黄嘌呤、黄嘌呤.%　　In this paper the chemical compositions of Ircinia fusca Carter 1880. were researched for the first time. Four compounds were separated by the silica gel column, the structures of which were determined as thymine, uracil, hypoxanthine and xanthine by means of UV, IR, EI-MS, 1H and 13C NMR.
