The qualitative composition and quantitative content of fatty acids in leaves of vegetable marrows (Cucurbita pepo L. var. giromontina Alef.), zucchini (Cucurbita pepo L. var. cylindrica Paris) yellow- and green-fruits varieties were determined by using GC/MS. 14 fatty acids were identified as the result of the experiment. Unsaturated fatty acids were found to be dominated in the raw plant material. The total content of unsaturated fatty acids amounted to 60.47% in vegetable marrows leaves, 64.35% yellow zucchini leaves and 68.85% green zucchini leaves, among which linoleic and linolenic acid dominated. The related health lipid indices (IA, atherogenicity, IT, thrombogenicity and IH, health) were determined. It is shown that the use of such biological resources is actual and expedient for the purpose of alimentary correction of the physiological condition of a person.

Abstract Fatty acid composition of foods has a great impact on nutrition and health. Therefore, thе determination and knowledge of the fatty acid composition of food is very important for nutrition. Due to the high nutritional characteristics of ostrich meat and its products, the research determining their quality is of topical interest. The aim of the present investigation was the determination of fatty acid composition of ostrich adipose tissue. The content of fatty acids was determined according to AOAC Official Methods of Analysis and determination was performed using a gas chromatograph with a flame-ionization detector (GC-FID). The results are expressed as a percentage of the total content of fatty acids. The method was validated and whereupon the following parameters were determined: linearity, precision, recovery, limit of detection and limit of quantification. The repeatability was within of 0.99 to 2.15%, reproducibility from 2.01 to 4.57%, while recovery ranged from 94.89 to 101.03%. According to these results, this method is accurate and precise and can be used for analysis of fatty acids in foods. It was concluded that the content of saturated fatty acids (SFA) accounted 34.75%, of monounsaturated fatty acids (MUFA) 38.37%, of polyunsaturated fatty acids (PUFA) 26.88%, of total unsaturated fatty acids (UFA) 65.25% and of desirable fatty acids (DFA) (total unsaturated + stearic acid) 70.37% of the analysed samples. The ratio polyunsaturated/saturated fatty acids accounted 0.77. The most present fatty acid is the oleic (C18:1n9c) with 28.31%, followed by palmitic (C16:0) with 27.12% and linoleic (C18:2n6c) acid with 25.08%. Other fatty acids are contained in significantly lower quantities.

In science vicasol is known to be relative to the energy and antioxidant systems of tissues closely related to the biosynthesis and oxidation of fatty acids. This effect may cause changes in the fatty acid composition of tissues, and numerous works on the positive effect of quinones and their derivatives on the myocardial function, suggest that the proper dose and feeding can increase the stability and productivity of poultry. The given was aims to study the effect of vicasol on the fatty acid composition of goose myocardium. Myocardium was chosen as a biological object. Biological material was collected every 7 days throughout the period from the 21st to the 35th day of ontogeny, characterized by the state of physiological tension of geese. Feeding of geese with vicasol at a dose of 0.7 mg / kg body weight began with the 3rd day of ontogeny. Fatty acid analysis in myocardial tissues was performed by gas-liquid chromatography, pre-fabric samples were processed with the method by Palmer (1971) to obtain tissue lipid extracts. According to the results of the study, due to various changes in the content of the entire spectrum of fatty acids of the tissue during the experiment - the use of vicasol causes a slight increase in the unsaturation and the total content of unsaturated fatty acids in the myocardium of geese. These fluctuations are realized depending on the physiological state of the body. where vicasol can stimulate both the biosynthesis processes of individual fatty acids and their mitochondrial and microsomal oxidation, as evidenced by multidirectional reliable changes in the content of their entire spectrum. In particular, on the 21st day, the content of docosopentaenoic acid increased by 36.3% whereas the content of docosohexaenoic and linolenic acids decreased by an average of 21–24%, on the 28th day the content of eicosatetraic and docosahexaenoic acids increased whereas the content of the linoleic acids dropped by 22.6% in control groups. On the 35th day, the content of basic unsaturated fatty acids: palmitooleic, linoleic, linolenic and docosohexaenoic acids increased in the tissue under the influence of vicasol with complete depletion of docosopentaenoic acid. These fluctuations in fatty acid composition cause a slight increase in the total content of unsaturated fatty acids and increase the unsaturation of myocardial lipids on the 28th and 35th days of ontogeny of geese. Based on previous results regarding the antioxidant state of myocardium affected by vicasol and the given findings, which prove changes in the content of the entire spectrum of fatty acids during the selected ontogeny, vicasol can be used in poultry farming as a tool to improve the quality and the resilience of poultry.

Представлены результаты исследования питательных веществ и жирнокислотного состава сеяных и естественных травостоев, хвощовых и безхвощовых (разнотравных) пастбищ Якутии. Установлено, что в составе липидов овса посевного доминируют ненасыщенные жирные кислоты (56,59 %), у отавы естественного травостоя этот показатель почти 2 раза меньше (31,15 %). Хвощ пестрый также содержит значительное количество полиненасыщенных жирных кислот, особенно линолевой и арахидоновой. Хвощовое пастбище превосходит разнотравное по содержанию в растительности протеина, жира, золы и БЭВ, за исключением клетчатки. Полученные нами результаты свидетельствуют о необходимости широкого использования посевов овса и хвощовых пастбищ для нажировки табунных лошадей якутской породы. The article presents the results of the study of nutrients and fatty acid composition of seeded and natural grasslands, horsetail and horsetail-free pastures in Yakutia. It was found that unsaturated fatty acids dominate in the composition of oat lipids, the total content of which was 56.59 %, while the natural grass stand oats have almost 2 times less (31.15 %). Variegated horsetail contains a significant amount of polyunsaturated fatty acids, especially linoleic and arachidonic. Horsetail pasture is superior to mixed grass pasture in terms of protein, fat, ash and nitrogen-free extractive fraction, except fiber. The results that we obtained indicate the need for widespread use of oat crops and horsetail pastures in breeding herd horses of the Yakut breed.

Refining of crude red fruit oil (CRFO) through the degumming and neutralization steps intended to produce oil free of impurities (non triglycerides) such as phospholipids, proteins, residues and carbohydrates, and also reducing the amount of free fatty acids (FFA). This study aims to determine the effect of red fruit oil purification through degumming and neutralization stages on chemical properties, fatty acid composition, carotenoid content and tocopherol of red fruit oil (RFO). The results showed that degumming of CRFO did not affect the decrease in water content, FFA levels, peroxide numbers, iodine values, carotenoids and tocopherols content; but decrease in levels of phosphorus, β-carotene and α-tocopherol. Neutralization of degummed-RFO (DRFO) did not affect the decrease in water content, iodine value, carotenoid, tocopherol and α-tocopherol; but the FFA levels, peroxide number, phosphorus and β-carotene levels decreased significantly. The fatty acid composition of RFO was dominated by unsaturated fatty acids (± 75%), which increases through degumming and neutralization stages. β-carotene is more sensitive than α-tocopherol during refining process of crude oil, but in general, this process can improve the RFO quality.

Palado (Aglaia sp) is a plant that grows wild in the forest around Mamuju regency of West Sulawesi, Indonesia. This plant is locally known as palado. Palado seeds (Aglaia sp) can be used as a source of vegetable oil because it contains approximately 14.75 % oil, and it has the potential to be used as food ingredients or as raw material for oil production. The purpose of this study was to determine the chemical properties and the composition of fatty acids contained in palado seed oil (Aglaia sp). The employed method involved the use of palado fruit that had been processed to be palado seed and undergoing flouring process. Palado flour was produced by the extraction process by using chloroform solvent with the soxhlet method. The characteristics of the chemical properties in the oil produced were analyzed by using a standard method, including iodine, saponification, and acid values. The analysis of fatty acid composition was conducted by using gas chromatography. The results showed that palado oil extracted with hexane had an iodine value of 15.38 mg/g, saponification value of 190.01 mg KOH/g, and acids value of 1.961 mg KOH/g. The fatty acid composition of the palado seed oil consisted of saturated fatty acids (41.601 %), which included palmitic acid (41.062 %), myristic acid (0.539 %), and unsaturated fatty acids (45.949 %), which included mono-unsaturated fatty acids (MUFA) such as (22.929 %), oleic acid and poly-unsaturated fatty acids (PUFA), which was linoleic acid (23.020 %).

ABSTRACT The fatty acid composition of cholesterol esters, phospholipids, and triglycerides of the serum has been studied in groups of hyperthyroid and hypothyroid women and also in control material matched for age. In hyperthyroidism, a decrease in the proportions of linoleic acid and an increase in the proportions of some saturated and mono-unsaturated fatty acids were observed. When absolute concentrations were considered, it appeared that the decrease in linoleic acid was almost equivalent to the entire decrease in total fatty acids in the serum of the hyperthyroid patients. In hypothyroidism no changes were noted in the proportions of linoleic, saturated and mono-unsaturated fatty acids, and the absolute concentrations reflected the general increase in serum lipids. It is believed that these findings may be explained by the changes in lipid turnover which are known to occur in disturbances of thyroid function. In hyperthyroidism, they lead to a linoleic acid deficiency, while a sparing effect must be operating in hypothyroidism. The finding of relatively high linoleic acid values combined with hyperlipaemia in hypothyroidism seems to be characteristic of the condition, since other types of hyperlipaemia are almost invariably combined with low percentages of linoleic acid. Results regarding arachidonic and eicosatrienoic acid are consistent with increased synthesis in hyperthyroidism, and decreased synthesis in hypothyroidism.

Salinity stress is a limiting factor for the growth and yield quality of rapeseed. The potentiality of melatonin (MT; 0, 25, 50, and 100 µM) application as a seed priming agent in mediating K+/Na+ homeostasis and preventing the salinity stress mediated oxidative damage and photosynthetic inhibition was studied in two rapeseed cultivars. We found that 50 µM MT treatment imparted a very prominent impact on growth, metabolism of antioxidants, photosynthesis, osmolytes, secondary metabolites, yield, and fatty acids composition. Days required for appearance of first flower and 50% flowering were decreased by MT application. Exogenous MT treatment effectively decreased the oxidative damage by significantly declining the generation of superoxide and hydrogen peroxide under saline and non-saline conditions, as reflected in lowered lipid peroxidation, heightened membrane stability, and up-regulation of antioxidant enzymes (catalase, superoxide dismutase, and ascorbate peroxidase). Furthermore, MT application enhanced the chlorophyll content, photosynthetic rate, relative water content, K+/Na+ homeostasis, soluble sugars, and proline content. Moreover, MT application obviously improved the oil quality of rapeseed cultivars by reducing glucosinolates, saturated fatty acids (palmitic and arachidic acids), and enhancing unsaturated fatty acids (linolenic and oleic acids except erucic acid were reduced). Yield related-traits such as silique traits, seed yield per plant, 1000 seeds weight, seed oil content, and yield biomass traits were enhanced by MT application. The anatomical analysis of leaf and stem showed that stomatal and xylem vessels traits are associated with sodium chloride tolerance, yield, and seed fatty acid composition. These results suggest the supportive role of MT on the quality and quantity of rapeseed oil yield.
