Abstract: Objective To explore the proportioning oils effects on erythrocyte fatty acids in rabbits with hyperlipemia.Methods Change of the components and contents of erythrocyte fatty acids in 50 rabbits fed on the natural proportioning oils on three months were determined by GC method.Results The oleic acid(18:1)and monounsaturated fatty acids(MUFA) were apparently increased in hyperlipemia control group.The level of-linolenic acid(18:3)was apparently increased in three test groups after being fed on the hyperlipemia forage and the proportioning oils.The highest content of 18:3 was showed in test I group and the contents of-linolenic acid(18:3)and linoleic acid(18:2)were apparently increased in test and group in which 18:1 and MUFA were no significantly change.Conclusion The level of n₃ polyunsaturated fatty acid may be increased by supplement of three proportioning oils.The dynamic balance of n₆/n₃ ratio may also be kept in the body by supplement of the pro portioning 2 oil.The proponioning 2 and 3 oils have more fairly good effect on prevention and treatment of hypelipemia.
