The fatty acid composition of dietary oils can modulate the incorporation of triacylglycerol-rich lipoproteins (TRL) into hepatocytes, thus affecting the atherogenicity of these particles. However, nothing is known about the effect of the unsaponifiable fraction of the oils. In the present study, we evaluated the influence of these components on the uptake of TRL by rat primary hepatocytes. TRL...

This study was designed in order to correlate the flavonoid and lipoidal matters content of Spinach roots and flowers to their hypolipidemic potential. The total flavonoid content was measured via complexation with aluminum chloride while determination of fatty acids methyl esters and unsaponifiable matters contents in both organs was performed using GC/MS. In an in vitro study, the crude etha...

The petroleum ether extract of the oleo-gum-resin of Boswellia carteri Bird., the chloroformic successive extract of the oleo-gum-resin of Commiphora myrrha Engl. as well as the prepared volatile contents from both resins showed significant anti-inflammatory activity in carragennan-induced edema in rats. Phytochemical investigation of the volatile fractions was carried out using GC/MS and revea...

Interest in the health-promoting effects of virgin olive oil, an important part of the "Mediterranean diet", prompted us to determine the antiinflammatory effects of erythrodiol, beta-sitosterol and squalene, identified as major components of the so-called "unsaponifiable fraction" of virgin olive oil, as well as of the phenolic compounds from the "polar fraction": oleuropein, tyrosol, hydroxyt...

Pure olive oil triglycerides (POLO), free from all unsaponifiable matter, were isolated from Virgin Spanish olive oil (COLO) by alumina-charcoal column chromatography. COLO and POLO were used as sources of dietary fat in two animal studies. The responses of serum and liver lipids to the two types of dietary fat were examined. Our results show that animals fed POLO-diet gave somewhat higher seru...

as one of the major constituents, accounting for about 16% of the unsaponifiable matter and about 35% of the hydrocarbon fraction. Some preliminary chemical tests were made for the fatsoluble vitamins, and the presence ofa small amount of vitamin E in human sebum was reported. A more complete study of the unsaponifiable matter has now been made, and this material has been more thoroughly examin...
