Octadecadienoic Acids

The complete fatty acid composition of fats and oils can be readily determined by use of silicic acid – silver nitrate column chromatography in conjunction with gas–liquid chromatography, permanganate–periodate oxidation, hydrazine reduction, and infrared analysis. These techniques were used to demonstrate the occurrence of trans-5-hexadecenoic (2.6%) and trans-5,cis-9-octadecadienoic (4.6%) acids in the seed oil of Thalictrum venulosum. The oil contains two predominant and one minor system of fatty acids: (i) trans-5-hexadecenoic, trans-5-octadecenoic, trans-5,cis-9-octadecadienoic, trans-5,cis-9,cis-12-octadecatrienoic; (ii) cis-9-hexadecenoic, cis-9-octadecenoic, cis-9,cis-12-octadecadienoic, cis-9,cis-12,cis-15-octadecatrienoic; and (iii) cis-5-hexadecenoic, cis-5-octadecenoic, cis-5-eicosenoic.

Abstract Introduction. With due consideration of the properties of fatty acids, as well as their importance for normal life activity and human development, research into the fatty acid composition of poorly studied plants and the search for new domestic plant sources of polyunsaturated fatty acids is a mainstream trend in modern pharmacy. Aim. Aim of research – determination of fatty acid qualitative composition and content in threshed grass, stalks, roots and seeds of Night-scented stock ‘Queen of Night’ and ‘Evening Scent’ cultivars as grown in Ukraine. Methods. Gas chromatography. Results. Both cultivars of Night-scented stock taken for analysis had similar fatty acid composition – 5 saturated, 5 (4 for seeds) monounsaturated and 2 polyunsaturated fatty acids, Quantitatively, in all tested parts of the herb polyunsaturated and monounsaturated fatty acid dominated, making in total 88.92% and 88.62% in the seeds of Queen of Night and Evening Scent cultivars, respectively, and averaging 65% in other parts of the tested cultivars. Linolenic and linoleic acids prevailed among the polyunsaturated fatty acids, whereas oleic acid prevailed among the monounsaturated. Conclusion. Night-scented stock can be utilized as a source of polyunsaturated fatty acids for the development of drugs and for standardization of tested raw materials.

We used conscious, chronic lymph-fistula rats to compare intestinal lymphatic transport of glycerol trioleate (TO) vs. glycerol trielaidate (TE) and to determine the effect of TO vs. TE on absorption and transport of cholesterol. Rats were implanted with intestinal lymph fistulas and duodenal cannulas and then given intraduodenal infusions of lipid emulsions containing purified TO or TE (40 mumol/h) and cholesterol (7.8 mumol/h + 2 microCi [14C]cholesterol). Lymph samples were collected at 0, 2, 4, 5, 6, 7, and 8 h after the start of lipid infusion. Lymphatic output and luminal and gut wall recovery of radioactive lipid at 8 h were quantified. Triacylglycerol (TG) fatty acid isomers did not affect lymphatic output of TG; lymph TG fatty acid composition and output reflected infusate composition. Lymphatic output of cholesterol (mass and radioactivity) did not differ between groups; luminal and gut wall recovery of [14C]cholesterol was also similar between groups. Similar lymphatic transport of TG and cholesterol between triolein- and trielaidin-infused rats was maintained for up to 16 h after the cessation of an infused lipid load. These results indicate that TO and TE are transported into lymph similarly, and that cholesterol absorption and transport are similar irrespective of whether TO or TE is the TG source. The data suggest that trans fatty acid-induced hypercholesterolemia is not due to altered intestinal absorption and transport of cholesterol.
