Food Staples

Sorghum and millet are important food staples in semi-arid tropics of Asia and Africa. Sorghum and millet are cereal grains that have prospective to be used as substitute to wheat flour for celiac patients. These are considered as the good source of many important and essential fatty acids. The volatile profiling of these two important crops is comparable to other cereals as well. The present study was an effort to explore biochemical composition of commercially available sorghum and millet varieties with special reference to their fatty acid and volatile profiling. Chemical composition of sorghum and millet was determined according to respective methods. Fatty acid methyl esters were prepared and then subjected to GC-FID for fatty acids analysis. The results indicated that both sorghum and millet oils are rich in essential fatty acids comprising mono and polyunsaturated fatty acids. Main fatty acids that are identified in current study includes palmitic acid, oleic acid, palmitoleic acid, behenic acid, linoleic acid, linoleic acid, stearic acid, myristic acid, etc. On the other hand volatile compounds from sorghum and millet were determined by preparing their respective volatile samples by using calvenger apparatus with suitable volatile extracting solvent. Volatile samples were then subjected to GC-MS analysis and respected results were compared with NIST library. About 30 different volatiles were identified in millet varieties while 35 different compounds were discovered in sorghum varieties belonging to aldehydes, ketones, benzene derivatives, esters, alcohols, sulphur compounds.

The fatty acid composition of the moss species Atrichum undulatum (Hedw.) P. Beauv. (Polytrichaceae) and Hypnum andoi A.J.E. Sm. (Hypnaceae) collected in winter time were analyzed by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) as a contribution to their chemistry. Eight fatty acids were identified in the chloroform/methanol extract 1:1 of A. undulatum (linoleic acid 26.80%, palmitic acid 22.17%, ?-linolenic acid 20.50%, oleic acid 18.49%, arachidonic acid 6.21%, stearic acid 3.34%, cis-5,8,11,14,17-eicosapentaenoic acid 1.52% and behenic acid 1.01%), while six fatty acids were found in the same type of extract of H. andoi (palmitic acid 63.48%, erucic acid 12.38%, stearic acid 8.08%, behenic acid 6.26%, lignoceric acid 5.16% and arachidic acid 4.64%). According to this study, the moss A. undulatum can be considered as a good source of both essential fatty acids for humans (linoleic acid and ?-linolenic acid) during the winter.

Fatty Acid Compositions

Lipids, extracted from the adrenals, brain, erythrocytes, heart, kidney, liver, plasma, and spleen of normal healthy female mink, were transesterified with 1% sulphuric acid in methanol, and the resulting methyl esters were analyzed by gas–liquid chromatography after purification by thin-layer chromatography. All of the tissues examined contained higher concentrations of unsaturated than of saturated acids, the highest levels of unsaturated acids occurring in the lipids of heart, adrenals, and plasma, and of the essential fatty acids (ω6 series, with six carbon atoms after last double bond) in plasma, erythrocyte, and kidney lipids. The fatty acid compositions of mink tissues resemble those reported in the literature for the rat; detailed comparisons are not possible because of the known influence of dietary factors on tissue fatty acids.

1. Rats were fed on either a diet deficient in essential fatty acid (EFA) or one supplemented with dihomo-γ-linolenic acid (20:3,n-6) at levels that represented 0.25, 0.5, 1.0 and 2.0% of the dietary energy.2. Supplementation of the diet of EFA-deficient animals with 20:3,n-6 reversed most of the fatty acid changes induced in the liver phospholipid fraction.3. The EFA potency of 20:3,n-6 was found to be similar to that of γ-linolenic acid (18:3,n-6) which has been shown to be higher than that of linoleic acid (18:2,n-6).

Composition Analysis

Physical properties of commonly grown Sri Lanka groundnuts cultivars and promising accession varied considerably and numbers of kernels, pod beak, reticulation, testa colour, and shell out percentage have differences among groundnuts. However, they showed more similarities for most of the characters. Moisture (5.4-8.4%), crude protein (18.7-28.5%), lipid (43.4-53.0%), ash (4.4-5.8%), carbohydrates (9.3-18.2%) and energy level (565.7-618.2kcal) contents varied considerably. Quality and flavor of edible groundnuts and its products are affected by fatty acid composition of oil. Lipids were mainly composed of mono and polyunsaturated fatty acids (>78% of the total lipids). Fatty acid composition analysis indicated that oleic acid (C18:1) was the main constituent of monounsaturated lipids in all seed samples. With the exception of ANKG1, linoleic acid (C18:2) was the major polyunsaturated fatty acid. The saturated fatty acids (Palmatic, Stearic acid and behenic acid) in different cultivars ranged between 10.2 to 15.6%, 2.5 to 6.3% and 1.1 to 5.3%, respectively. Differences among cultivars for oleic acid exhibited significance which ranged between 38.2 to 47.4%. Similarly, cultivars differed statistically for linoleic acid which showed a range of 23.1 to 38.7%. Oleic to linoleic acid ratio was differed and all the released varieties were below the minimum standard level of 1.6, whereas ICGV 86590 and ICGV 00073 showed higher O/L ratio of 1.94 and 1.75 respectively.

Fatty acids are known for their regulatory role in inflammation and oxidative stress. The present study investigated 38 calves born from dams, abomasally supplemented with coconut oil, essential fatty acids (EFA), conjugated linoleic acid (CLA) or EFA + CLA, according to immunological traits and the oxidative and anti-oxidative status for the first 5 days of life. On day 2 of life, plasma total bilirubin, cholesterol, interleukin 1-β and ferric ion reducing anti-oxygen power (FRAP) were lower in calves with than without maternal EFA supplementation, and FRAP additionally on day 4. On day 3, the concentrations of reactive oxygen metabolites were higher in calves with than without maternal EFA supplementation and additionally on day 5 together of retinol. Total leucocyte counts were decreased in the EFA group compared to the CLA group on day 5. Lymphocyte proportions decreased from day 1 to 5 only in the EFA + CLA group. On day 2, plasma total protein was higher in CLA and EFA + CLA than in EFA calves. Similarly, CLA calves had higher interleukin 1-β concentrations compared to EFA + CLA calves. FRAP was decreased by CLA on day 4. Overall, the maternal fatty acid supply affected the inflammatory response and the oxidative and anti-oxidative status of the neonatal offspring.

Background:Inhibition of fatty acid synthase leads to apoptosis in cancers, which leads to high levels of fatty acid synthesis. This indicates that cancer cells depend on fatty acid in order to survive. In this study, we investigated whether or not there was a relationship between the glial tumor grade and free fatty acid level of tumor tissue.Methods:Twenty patients who had high grade glial tumors and 20 patients who had low grade glial tumors, were included in the study. Tumors samples were obtained intraoperatively in order to measure the fatty acid levels. The fatty acids were studied in three groups: saturated fatty acids, monounsaturated fatty acids and polyunsaturated fatty acids. They were analyzed with gas chromatography.Results:The oleic acid, linoleic acid, eicosadienoic acid, arachidonic acid, and docosadienoic acid levels were high in the tumor tissue of low grade tumors. The myristic acid, palmitic acid, stearic acid, alpha linoleic acid, eicosenoic acid, dihomo-gamma-linolenic acid, docosahexaenoic acid, and ceramide levels were high in the tumor tissue of high grade glial tumors. However, none of these high values were statistically significant. The high values of behenic acid, a saturated fatty acid, in low grade glial tumors were statistically significant.Conclusion:High levels of behenic acid in patients with low grade glial tumor is important as it indicates persistence of the tissue integrity and tissue resistance. behenic acid levels can be a prognostic factor in glial tumors.

1. Liver necrosis was produced in rats given diets deficient in selenium and vitamin E and the metabolism of [5-Me-14C]D-α-tocopherol was studied during the development of the disease. 2. When a torula yeast diet (containing sufficient of the yeast to provide essential fatty acids) was used, the addition of 5 % cod-liver oil fatty acid methyl esters produced only a slight decrease in the time taken to produce the disease, compared to controls given methyl oleate; methionine had little protective effect. The metabolism of the radioactive tocopherol was unaffected by dietary lipid, Se or methionine and was not influenced by the development of necrosis. 3. When a casein diet (devoid of fat and containing insufficient Se to prevent liver necrosis) was used, the addition of small amounts of linoleic acid to the diet (as 2 % maize oil fatty acid methyl esters) decreased the time taken to produce the disease and increased its incidence. However, the metabolism of the radioactive tocopherol was independent of dietary lipid or Se. 4. It would appear that either Se or vitamin E may be necessary for effective utilization of the ratapos;s requirement for linoleic acid.
