The effects of dietary conjugated linoleic acid (CLA) and linoleic acid (LA) on ketone body production and lipid secretion were compared in isolated perfused rat liver. After feeding the 1% CLA diet for 2 wk, the concentration of post-perfused liver cholesterol was significantly reduced by CLA feeding, whereas that of triacylglycerol remained unchanged. Livers from CLA-fed rats produced significantly more ketone bodies; and the ratio of β- hydroxybutyrate to acetoacetate, an index of mitochondrial redox potential, tended to be consistently higher in the liver perfusate. Conversely, cumulative secretions of triacylglycerol and cholesterol were consistently lower in the livers of rats fed CLA, and the reduction in the latter was statistically significant. Thus dietary CLA appeared to exert its hypolipidemic effect at least in part through an enhanced β-oxidation of fatty acids at the expense of esterification of fatty acid in the liver.

The five most widely accepted procedures for preparing fatty acid methyl esters in food lipids were investigated for their suitability in capillary gas-liquid chromatographic analysis of cis-9, trans-11 conjugated linoleic acid (c-9, t-11 CLA) in meat. A modified procedure of fatty acid methyl esterification was developed and the method was applied to determine c-9, t-11 CLA content in some meats. This method involved hydrolysis of lipids with 0.5M KOH in methanol at 100°C for 5min, followed by esterification with aqueous HCI (35%)/ methanol (1:1 v/v) at 100°C for 5min. The resulting c-9, t-11 CLA methyl ester was separated by gas-liquid chromatograph equipped with a capillary column and determined using tricosanoic acid as an internal standard. Meat from ruminant animals considerably contained more c-9, t-11 CLA than those from non-ruminant animals in the following order: goat meat, beef, mutton, pork, and chicken. The amount in goat meat (6.35mg/g lipid) was 10-fold greater than those in pork and chicken.

Accumulation of lipids in the liver, fatty acid composition and molecular species of serum and hepatic triglycerides were investigated after rats were raised for 4 weeks with diets containing beef powder and 12% level of various lipids. Some diagnostic parameters in the serum and acetyl-CoA carboxylase and peroxisomal β-oxidation activities of the liver were also examined. The accumulation of lipids in the liver of rats raised with beef tallow and with canola oil was significantly less than that with olive oil. Serum GOT of rats raised with beef tallow was significantly less than that of rats with vegetable oils. Serum GPT was also significantly less in rats with beef tallow than with safflower oil. Fatty acid composition of hepatic lipids was rather dependent on the composition of dietary lipids except in the case of safflower oil. Molecular species of triglycerides of hepatic lipids were quite different from those of dietary lipids, but the difference in the species between serum and hepatic triglycerides were smaller than the difference between dietary and hepatic lipids. Specific activities of acetyl- CoA carboxylase of the liver of rats raised with beef tallow and canola oil were significantly higher than that of rats with safflower oil, while peroxisomal β-oxidation activity of rats with beef tallow showed an intermediate value between olive oil and canola oil.
