Rapeseed oil-induced modifications in the fatty acid composition of lipids in some tissues of mice

Rapeseed oil-induced modifications in the fatty acid composition of lipids in some tissues of mice. Meneguz, A.; Michalek, H.; Gatti, G. L. (Lab. Farmacol., Ist. Super. Sanita, Rome, Italy). Riv. Soc. Ital. Sci. Aliment., 6(5), 357-62 (Italian) 1977. CODEN: RSISAZ. DOCUMENT TYPE: Journal CA Section: 18 (Animal Nutrition) To 4-5-wk-old female mice weighing ~20 g 50% of the daily cal were supplied intragastrically by rapeseed oil or in peanut oil (controls) for 3 consecutive days, after 3-h fasting. Rapeseed oil contained 52% erucic [112-86-7], 7.4% eicosenoic [26764-41-0] and 7.8% linolenic [463-40-1] acids. There was in the myocardium of rapeseed oil-treated mice a considerable deposition of erucic (7.8%), eicosenoic (2.5%), and linolenic (0.7%) acids, with a decrease of the sum of C18 fatty acids, i.e., stearic, oleic, and linoleic, with respect to control animals. The deposition of erucic (3.2%), eicosenoic (2.6%), and linolenic (2%) acids was less pronounced in skeletal muscle, with a decrease of oleic and linoleic acids. The deposition of erucic (1.6%), eicosenoic (1.3%), and linolenic (0.5%) acids was lowest in the kidney, and was not accompanied by decreases of any other fatty acids. Thus, deposition in mice of the fatty acids characteristic of rapeseed oil in some organs does not differ from that in rats and swine, while their elevated deposition in the liver appears to be a particular feature of mice. The erucic/eicosenoic acid ratio in all organs studied indicates that eicosenoic acid derives partially from b-oxidn. of erucic acid.

Enrichment of eicosenoic and docosadienoic acids from Limnanthes oil

Enrichment of eicosenoic and docosadienoic acids from Limnanthes oil. Chang, Shu-Pei; Rothfus, J. A. (NRRC, ARS, Peoria, Ill., USA). J. Am. Oil Chem. Soc., 54(11), 549-52 (English) 1977. CODEN: JAOCA7. DOCUMENT TYPE: Journal CA Section: 45 (Fats and Waxes) Crystn. of Limnanthes alba acids (eicosenoic 61, docosadienoic 19, and others 20%) in acetone (initial concn. 0.05 g/mL) at -50° enriches eicosenoic acid [26764-41-0] (74%) in the ppt. while concg. docosadienoic acid [26764-24-9] (70%) in the supernatant fraction. The method is suited for large-scale lab. sepns.
