gundelia tournefortii l. is a well known plant in mountains of iran and is found all over the country. it traditionally has some medicinal applications. in this research, gundelia tournefortii l. seed was studied as a source of edible oil. oil was extracted with immersion method using diethyl ether as a solvent. acidity, saponification, ester, iodine, peroxide and refractive indices, average mo...
The hypothesis that the unsaponifiable fraction of olive oil dramatically influences hepatic gene expression was tested in mice. Two olive oils, obtained from the same olive cultivar but by different technological procedures, were characterized to show that they differed mainly in terms of the composition/quantity of this unsaponifiable fraction. Using DNA microarrays, hepatic gene expression w...
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...
Gas-liquid chromatographic (GLC) determination of vitamin D in multivitamin preparations containing excess amounts of vitamin E (a more than 2,500 weight ratio of dl-alpha-tocopheryl acetate to vitamin D) was investigated and a simplified routine method was established because the method reported previously (1) could not be applied to such special preparations. After applying the unsaponifiable...
Mycoplasma sp., strain J, which is unable to convert mevalonic acid to isopentenyl pyrophosphate (IPP) will grow with IPP as a substitute for sterol. (14)C-labeled IPP is incorporated into its unsaponifiable lipid. This unsaponifiable lipid was separated into three (14)C-labeled fractions, all of which possess spectral and chromatographic characteristics of polyterpenes.
