Camelina sativa L is a cruciferous oilseed plant. This plant is cultivated as an oilseed crop mainly in Europe and in North America and over the past years the cultivation has arranged in our country. The analyzed oil is obtained from the seeds of Camelina sativa L, growing in Bornuur, Tuv province. The goal of this study was to determine the physical and chemical characteristics and fatty acids composition of Camelina sativa L seed oil cultivated in Mongolia. According to our analysis total lipid was determined 38.52 %, moisture 4.80 % and total mineral elements 4.02 %, respectively. Mineral elements in Camelina sativa L seeds contain calcium (0.56 %), phosphorous (1.22 %), potassium (1.39 %), magnesium (0.53 %) in dominated amounts; iron, zinc, manganese and copper in trace amounts. Eight nonessential amino acids in seeds of this plant with total amount of 75.9 % were identified; phenylalanine was detected in highest amount among the all identified amino acids, while lysine, tryptophan and arginine are followed. The following characteristics in Camelina sativa seeds oil were determined. The refractive index was 1.4774 at 20°C, the peroxide value of fresh oil was 0.03 meq H2O2 /kg, saponification value 185.8 mg KOH/g, iodine value 143.33 g J2 and acidic value 6.27 mg KOH /g. Carotenoid was determined as 16.77 mg %, by spectrometry in Camelina sativa seeds oil. The analysis of fatty acids composition showed that there are 12.5 % saturated and 87.5 % unsaturated fatty acids. In particular, oleic acid (C18:1) 14.0 %, linoleic acid (C18:2) 9.0 %, α-linolenic acid (C18:3) 10.5 % and gondoic acid (C20:1) 32.8 %, were composed the major part of unsaturated fatty acids.

Brown adipose tissue in newborn lambs accounts for 4.52% of total body weight, then during postpartum period it intensively decreases, reaching 1.5% after a week, and finally it is gradually adsorbed or replaced with white adipose tissue. Fatty acids composition of lamb brown adipose tissue includes 17 unsaturated fatty acids (53.23%) and 11 saturated ones (46.95%).Mongolian Journal of Agricultural Sciences Vol.15(2) 2015; 38-42

In order to confirm the substitutability of palm oil for lard, the fatty acid composition and their distribution at the Sn-2 position of triglycerides in three kinds of palm oil products and five kinds of lard products were investigated. The results obtained were as follows. Palm oil has similar saturated fatty acids composition (C16:0, C18:0, C18:1, C18:2) with lard, and has slightly lower unsaturated fatty acids content than lard. The Sn-2 position of palm oil is mainly distributed with unsaturated fatty acids (C18:1, C18:2), while the Sn-2 position of lard is mainly distributed with saturated fatty acids (C16:0, C18:0), which is maybe the cause why palm oil is easier to be digested and absorbed than lard.

In the fatty acid composition of total lipid of the soft coral Bebryce sp., the concentration of unsaturated fatty acid predominates. The composition of saturated fatty acids is very diverse, including all saturated fatty acids from C14 to C26. The unsaturated fatty acids with high concentration are C20: 4n-6, 20:5n-3, 22:6n-3, 24:5n-6, 26:3n-6, 26:2n-6, 26:2n-7, 28:3n-6. In the fatty acids composition of the studied coral, there is presence of characterized fatty acids for the existence of sponges C25-C28 (demospongic fatty acids) with total content 29,86%. Most of the Bebryce coral species do not have zooxanthellae, therefore, in the fatty acids composition, either it is lack or contains only a small amount of markers fatty acids for zooxanthellae such as 18:5n-3, 18:4n-3, 18:3n-6, 20:4n-3. In the phospholipid content of the soft coral Bebryce sp., there is presence of characterized classes for Cnidarian animals such as phosphatidylethanolamine (PE), phosphatidylchonline (PC), phosphatidylserine (PS), phosphatidylinositol (PI), phosphonolipid is ceramide aminoethylphosphonate (CAEP). PC account for the highest concentration (37,20% of total phospholipid). The molecular species of phospholipid classes of Bebryce sp. for the first time were investigated. In the results, there we 60 phospholipid molecular species identified in 5 classes. The molecular species with high content in the classes were PE 20:4/18:1e, PE 20:4/19:1, PC 20:4/18:0e, PC 20:4/16:0e, PS 24:5/18:0e, PI 24:5/18:0, CAEP18:2base/16:0 and CAEP 18:1base/16:0.

The fatty acids composition and antioxidant activity have been determinate for cold press walnut oil. It has been found that the total saturated fatty acids have been 8.8 % while poly unsaturated fatty acids have been 72.84 %. The ratio between omega-6 and omega-3 has been determined as 5.06 which could help in human healthy diet. On the same side, the antioxidant activity of the oil is very high at a level of 3.65 mmol L-1 and a ratio between lipophilic and hydrophilic fractions of 9.45.

Objective: The aim of this study was to determine the fatty acids composition in a macadamia seeds oil sample cultivated in Ecuador.Materials & Methods: macadamia oil was obtained of macadamia seeds using the cold pressing method. Fatty acids analysis was carried out using the Gas Chromathography method with a Mass Selective Detector (GC/MSD) and using the data base Library NIST14.L to identify the compounds.Results: macadamia seeds have a high content of unsaturated fatty acids with 41.36% of oleic acid. Macadamia seeds oil has 37.77% of polyunsaturated fatty acids of which 3.79% ɷ6 α- Linoleic and 33.98% of ɷ3 α- Linolenic. Macadamia seeds only have 9.33% of palmitic acid. Conclusions: Macadamia seeds are a good source of monounsaturated fatty acids oleic acid and with a good content of ɷ6 α- Linoleic and ɷ3 α- Linolenic. This profile enables their use as a good and healthy oil to be used in the food industry in Ecuador. Keywords: Macadamia, Macadamia integrifolia, Fatty acids, Gas chromatography-mass selective detector, Methyl ester, Omega acids.

Unsaturated fatty acid in food has an effect to improve human health, while saturated fatty acid has the opposite impact. Ratio between both types of fatty acids is important to evaluate the biological material for nutraceutical product development. This paper aimed to evaluate the nutraceutical potency of sea cucumber from Kendari Bay Waters, South East Sulawesi, based on their fatty acids composition. The analysis was conducted by the 1H-NMR (Hidrogen-Nuclear Magnetic Resonance) method. Several species within 4 genera (Holothuria, Bohadschia, Actinopyga, and Stichopus) were selected as the subject of the study. Comparison of fatty acid composition has been done in genera level, the preliminary study found that variation between species among the same genera was insignificant (p >0.05). Results of the study detected that Holothuria contained with an even ratio of Poly Unsaturated Fatty Acids (PUFA) and Saturated Fatty Acids (SFA), but Actinopyga was detected with low PUFA/SFA ratio. It may suggest that Holothuria from this region is the most potential raw material for nutraceutical product development. Meanwhile, precaution is needed for genera that contained with low PUFA/SFA ratio. Furthermore, comparison with other studies detected that fatty acids composition is not morphological specific, but vary, according to food viability, environmental and geographic location. Therefore, preliminary screening is important in evaluation of sea cucumber material for nutraceutical product development.
