Abstract

Plant sterols were found by gas liquid chromatography in the sterols of five species of aquatic vertebrates; mackerel (Scomber japonicus), rainbow trout (Salmo gairdnerii), smelt (Osmerus dentex), sardine (Sardinops melanosticta) and chimera (Chimera phantasma). The sterols of chimera liver, sardine flesh and sardine viscera contained 9.0, 2.4 and 3.1% of C28 and C29 sterols in addition to 86.7, 96.6 and 95.2% of cholesterol. The occurrence of norcholestandienol, campesterol, beta-sitosterol and C28 stanol was shown by combined gas chromatography-mass spectrometry. Sperm whale (Physeter catodon) sterols consisted of more than 99% cholesterol with only traces of 22-dehydrocholesterol.

摘要

通过气液色谱法在五种水生脊椎动物的甾醇中发现了植物甾醇；它们分别是鲭鱼（日本鲭）、虹鳟鱼（虹鳟）、胡瓜鱼（日本胡瓜鱼）、沙丁鱼（南美拟沙丁鱼）和银鲛（幻影银鲛）。除了分别含有86.7%、96.6%和95.2%的胆固醇外，银鲛肝脏、沙丁鱼肉和沙丁鱼内脏的甾醇中还含有9.0%、2.4%和3.1%的C28和C29甾醇。气相色谱 - 质谱联用分析表明存在去甲胆甾二烯醇、菜油甾醇、β-谷甾醇和C28甾烷醇。抹香鲸（巨头鲸）的甾醇中胆固醇含量超过99%，仅含有微量的22 - 脱氢胆固醇。
