Abstract

This study was carried out to investigate the effect of the feeding mixture of linseed oil, rich in n-6 PUFA on the lipid metabolism in the dietary hyperlipidemic rats. After male Sprague-Dawley rats were induced hyperlipidemia by feeding the diet containing lard, butter and cholesterol for 3 weeks. then they were fed with the diet containing lard 3.0% and butter 12.0% for control, the mixture in different proportion of both linseed oil and sunflower seed oil, and antihyperlipidemic drugs for 2 weeks. Analysis of the fatty acid composition of the brain and heart lipids showed following results. In the fatty acid composition of brain lipids, C20:4 and C22:6 were the major fatty acids but showed little difference among the groups. In the fatty acid of heart lipids,C18:2 was the major fatty acid. The proportion of C20:4 decreased gradually as n-3P/n-6P ratio of the test lipids increased in groups 5 (linseed oil 12.0%) to 9 (sunflower seed oil 12.0%) while the proportion of C22:6 was not affected by the fatty acid composition of the test lipids.
