摘　　要：目的　研究天然配比油对家兔肝组织中脂肪酸的影响。方法　用GC法测定 5 0只家兔喂天然配比油 90d肝组织脂肪酸组分和含量的变化。结果　猪油对照组中 14∶0、18∶1和MUFA明显增高 ;三个配比油组α18∶3水平明显增高 ,14∶0明显降低 ,配 1组的α18∶3含量最高 ,配 2和配 3组的γ18∶3和 18∶2含量明显增高、18∶1和MU FA无明显变化。结论　补充三种配比油均可提高体内n3系多烯脂酸水平 ;配比 2和配比 3油还可提高n6 系多烯脂酸质量、抑制 18∶1升高 。Objective The study was to explore the effects of natural proportioning oil on fatty acids in rabbit hepatic tissue.Methods\ Changes of the components and contents of hepatic tissue fatty acids in 50 rabbits fed on the natural proportioning oils for 90 days were determined by GC method.Results\ The levels of myristic acid(14:0),oleic acid(18:1) and monounsaturated fatty acids (MUFA) were apparently increased in lard control group, and the level of α linolenic acid (α18:3) was apparently increased and 14:0 was apparently decreased in three proportion groups after being fed on the proportioning oils. The highest content of α18:3 was showed in the proportion 1 group, and the contents of γ linolenic acid (γ18:3) and linoleic acid (18:2) were apparently increased in the proportion 2 and 3 groups in which 18:1 and MUFA were no significantly change after being fed on the proportioning oils.Conclusion\ The level of n 3 polyunsaturated fatty acid may be increased by supplement of three proportioning oils. The quality of n 6 polyunsaturated fatty acid may also be improved and the increasing of 18:1 may be inhibited in the body by supplement of the proportioning 2 and 3 oils. The proportioning 2 and 3 oils have more fairly good effect in treatment of hyperlipemia, and it was also discussed that whether the oleic fatty acid and α linolenic acid can be converted into docosahexaenoic acid.
