뱀장어 근육유의 지방질 및 sterol 조성을 GLC로 분석하였고 특히 sterols조성을 IR, NMR, GLC-MS로 동정하여 다음과 같은 결과를 얻었다. 1) 뱀장어 근육유의 지방산 조성은 $C_{18:1}(40.98\%),;C_{16:0}(23.71\%),;C_{16:1}(13.37\%)$산이 가장 높은 비율로 함유하며, 다음은 $C_{14:0}(7.19\%),; C_{18:0}(5.55\%),;C_{20:1}(1.83\%),;C_{18:2}(1.42\%)$산 이였고, $C_{18:3}(0.92\%),;C_{15:0}(0.73\%),;C_{14:1}(0.50\%)$산은 그 함량이 가장 적었다. 2) sterols 조성은 cholesterol$(96.58\%)$이 대부분이 였고, 24-methylene cholesterol$(3.43\%)$이 있음을 알았다.
The composition of fatty acids and sterols in the muscle lipid of eel, Anguilla japonicus Temminck & Schlegel was investigated quantitatively by using gas liquid chromatography(GLC) and the sterols separated from unsaponifiable matter by thin-layer chromatography were identified by GLC, infrared spectroscopy, nuclear magnetic resonance and GLC-mass spectrometry respectively. The fatty acids of the muscle lipid consisted of the large amount of C18:1 $(40.98\%)$, $C16:0(23.71\%)$, $C16:1(13.37\%)$ acids, and small amount of $C14:0(7.19\%),;C18:0(5.55\%),;C20:1(1.83\%),;18:2(1.42\%)$ acids, and $C18:3(0.92\%),;C15:0(0.73\%),;C14:1(0.50\%)$ acids were smaller, Choleterol$(96.58\%)$ was a major component of the sterol fraction and 24-methylene cholesterol $(3.42\%)$ was also detected as a minor component.
