摘要
本文分析测定了闽南近海常见鲨鳐类肝油的理化常数和角鲨烯含量。尖头斜齿鲨肝油的碘值特别高，说明其中脂肪酸的不饱和程度很高；非皂化物含量很低，约占肝油重的38×10－3（m／m）；角鲨烯含量极微，在肝油中仅占84×10－5（m／m）。闽南近海常见鲨鳐类肝油的角鲨烯含量均很低，变化在（31～116）×10－5（m／m）之间。在相同的气相色谱条件下，小孔沙条鲨和狭纹虎鲨肝油中没有检测到角鲨烯。
Physicochemical constants and squalene contents of liver oils from sharks and rays off southern Fujian coastal waters are determined in this paper. The iodine value of Scoliodon sorrakowah liver oil is particularly high, denoting a high degree of unsaturation in fatty acids. The content of unsaponifiable matter is low [about 38× 10-3(m/m) of liver oil], and that of squalene is very low [only 84 ×10-5(m/m) of liver oil] in S. sorrakowah. The contents of squalene in liver oils from sharks and rays analysed in this paper are very low, ranging from (31~116)×10-5(m/m) of the liver oils. In addition, squalene has not been detected in the liver oils of Negogaleus microstoma and Heterodontus Zebra at the same GC conditions.
