摘要:

在研究黄海繁茂膜海绵的天然产物时,发现5β-CHOLESTAN-3β-OL在其体内大量存在;通过1H NMR谱发现还有少量CHOLESTEROL的存在. 在GC-MS谱图中,并未分析得到CHOLESTEROL. 通过标准品5β-CHOLESTAN-3β-OL和CHOLESTEROL混合物的1H NMR谱图,对难分离的甾类化合物用1H NMR谱定量进行初探.

Abstract:

5β-CHOLESTAN-3β-OL was determined as the major steroids in marine sponge -Hymeniacidon perleve- with a level of ca. 1 000 ppm. Cholesterol was fou
nd in the 5β-CHOLESTAN-3β-OL crystal using 1H NMR spectroscopy, while GC-MS failed to obtain the same results. Using 1H NMR spectroscopy, standard mixtures of  5β-CHOLESTAN-3β-OL and cholesterol were studied to accurately quantify the steroids that are difficult to be separated by chromatography.

Key words: NMR, quantity, steroid, marine sponge, Chromatography, Hymeniacidon perleve
