The oil from the seeds of Borago officinalis L. (borage) is a major commercial source of ?-linolenic acid. The fatty acid has a great potential therapeutic value in the treatment of several diseases. In the present work the efficiency of high pressure extraction of borage seed oil containing ?linolenic acid in high concentrations was investigated. Extraction was performed by semicontinuous flow...

Metabolic syndrome is one of the major factors to increase the incidence of heart failure. In our study, we compared plasma fatty acid compositions among heart failure patients with and without Metabolic syndrome. Fatty acid (FA) composition of plasma phospholipids was analyzed and the activities of desaturase were estimated as the ratio of substrate and product fatty acids in 85 stable heart f...

Balsam fir needle retention and fatty acid profile changes due to cold acclimation throughout autumn, but little is known about the relationship between these two phenomena. The objective was examine differences in FAs contrasting abscission resistant balsam genotypes autumn early winter. Branches from with low high resistance (NAR) were collected September January analyzed for FA composition. ...

Cultures of the phytoflagellate Eugfena gracitis were grown at light intensities varying from 120 to 610 footcandles. With increasing light intensity, the content of chlorophyll and of total lipids declined, whereas the percentage of 4,7, 10,13-hexadecatetraenoic acid and of ar-linolenic acid rose sharply. The increased content of the two polyunsaturated fatty acids was even more pronounced in ...

Thirty-seven species of seaweeds including 10 Chlorophyta, 13 Phaeophyta, and 14 Rhodophyta collected from the coast of Nagasaki Prefecture, Japan, were screened for algicidal activity against the red-tide phytoplankton Heterosigma akashiwo. The green alga Ulva fasciata (Ulvaceae, Chlorophyta) showed the strongest algicidal activity among the seaweeds tested. Bioassay-guided fractionation of th...

Ultrasonic-assisted extraction was employed for highly efficient separation of aroma oil from raspberry seeds. A central composite design with two variables and five levels was employed and effects of process variables of sonication time and extraction temperature on oil recovery and quality were investigated. Optimal conditions predicted by response surface methodology were sonication time of ...

Epidemiological and clinical trial evidence suggests that omega-3 polyunsaturated fatty acids (PUFAs) might have a significant role in the prevention of coronary heart disease. Dietary sources of omega-3 PUFA include fish oils rich in eicosapentaenoic acid and docosahexaenoic acid along with plants rich in alpha-linolenic acid. Randomized clinical trials with fish oils (eicosapentaenoic acid an...
