The fatty acid contents of marine, brackish and fresh water fishes were identified and quantified by gas chromatography. It was found that marine fishes were better sources of n-3 fatty acids, whereas fresh and brackish water fishes were better sources of n-6 fatty acids. Marine fish had the highest amount of PUFA. Among PUFAs, docosadienoic acid (C22:2n6) and adrenic acid (C22:4n6) were identified in 20 fishes. EPA and DHA was significantly higher in marine fishes (p less gthan 0.01), particularly, Dussumieria acuta, the rainbow sardine (24.80 mg g-1). Gerres abbreviates, the silver belly (20.16 mg g-1) and Tricusurus savala, the wolf herring (23.34 mg g-1). The n-3: n-6 ratio was significantly higher in marine fishes (p less gthan 0.05) than in the brackish and fresh water fishes studied. Atherogenicity (AI) and thrombogenicity(TI) values were significantly higher in both fresh and brackish water fishes and significantly lower (p less gthan 0.01) in marine fishes.

Fatty acid compositions of seeds of five taxa of the Juniperus section of the genus Juniperus L. (Cupressaceae), i. e. J. drupacea Lab., J. communis L. var. communis, J. communis var. saxatilis Pall., J. oxycedrus L. subsp. oxycedrus, and J. oxycedrus subsp. macrocarpa (Sibth. & Sm.) Ball, were investigated. Methyl ester derivatized fatty acids of the lipophylic extracts of the five species were comparatively analyzed by capillary gas chromatography-mass spectrometry (GC-MS). Juniperus taxa showed uniform fatty acid patterns, among which linoleic (25.8–32.5%), pinolenic (11.9–24.1%) and oleic acids (12.4–17.2%) were determined to be the main fractions in the seed oils. Juniperonic acid was found to be remarkably high in J. communis var. saxatilis (11.4 %), J. oxycedrus subsp. oxycedrus (10.4 %), and J. communis var. communis (10.1 %). To the best of our knowledge, the present work discloses the first report on the fatty acid compositions of seeds of this Juniperus section grown in Turkey.

AbstractTotal lipid and the fatty acid compositions of phospholipid and triacylglycerol fractions, prepared from eggs, 3rd instars of larvae, pupae, male and female adults of Lertha sheppardi, were analyzed by gas chromatography and gas chromatography-mass spectrometry. The effect of diet (adults’ nutrition) on fatty acid composition of L. sheppardi adults was also investigated. Total lipid of L. sheppardi considerably increased in adults compared with immature stages. There was a significant decrease in total lipid level in larval stage in contrast with egg stage. Qualitative analysis revealed the presence of 14 fatty acids during all stages. The major components were C16 and C18 saturated and unsaturated components which are ubiquitous to most animal species. In addition to these components, one odd-chain (C17:0) and prostaglandin precursor fatty acids were found. The fatty acid profiles of phospholipids and triacylglycerols were substantially different. In phospholipid fraction, monounsaturated fatty acids were the major proportion of fatty acids in both sex of adults and pupae, whereas polyunsaturated fatty acids were the most dominant fatty acids in eggs and 3rd instars. Results of triacylglycerol fraction revealed that fatty acid composition of eggs had higher level of C16:1, C18:0 and C18:3n-3 content than that of 3rd instars and pupae, which suggests accumulation of energetic and structural reserve materials during embryonic development. At more advanced developmental stages, mainly in adult females, the amount of C16:1 increased once again, which may be related to the need for accumulation of sufficient energy and of carbon reservoir in the developing new vitellum. Percentages of C18:1 were significantly high in adult stages compared to other stages. These findings indicate that the accumulation and consumption of fatty acids fluctuate through different development stages. Diet did not effect the fatty acid composition of L. sheppardi adults.

This study investigated the fatty acid compositions, moisture content, ash content and heavy metals in ten marine fish samples namely, Lates calcarifer, Tenualosa toli, Pampus chinensis, Laptoracanthus savala, Harpodon nehereus, Johnius angentatus, Awaous guamensis, Setipinna phasa, Sillogenopsis panigus, Sardina pilchardus collected from Kuakata sea beach, Bangladesh. Analysis was carried out according to AOAC (1990) method. Fatty acid compositions were determined by saponification and esterification followed by identification and quantitation by gas chromatograph equipped with flame ionization detector (GC-FID). Ash, fat and moisture contents of the fish samples were in the range of 3.25-6.27%, 0.89-6.08% and 71.47-90.16%, respectively. The amount of saturated fatty acids (SFA) varied in the range of 55.53-89.04% whereas unsaturated fatty acids (USFA) were of 16.45-44.48%. Lauric (3.93-15.19%), palmitic (40.27-67.34%) and stearic acids (5.18-22.88%) were predominant among the individual SFA compositions, whereas oleic (0.91-34.26%), linoleic (0.69-9.95%) and palmitoleic acids (7.66-19.05%) were predominant among USFA in these species. Samples were freeze dried, digested and finally analysed by atomic absorption spectroscopy (AAS) for the presence of Pb, Cu, Zn, Mn and the range of these metals were 0.5-1.9, 2.4-30.4, 3.2-10.5, 0.3-8.5 mg.kg-1, respectively. However, the values were below the permitted level set by FAO/WHO 2004.

Priatni S, Ratnaningrum D, Kosasih W, Sriendah E, Srikandace Y, Rosmalina T, Pudjiraharti S. 2018. Protein and fatty acidprofile of marine fishes from Java Sea, Indonesia. Biodiversitas 19: 1737-1742. Indonesia is the second largest producer of capturefisheries products in the world and the most capture fisheries production comes from marine fisheries. Marine fish is a source of protein,amino acid, saturated and unsaturated fatty acids, which are important components of diet. The objective of the study was to investigatethe protein and fatty acids profile of nine marine fish samples from Java Sea of Indramayu West Java, Indonesia. The analysis datashowed that the total protein content of fish samples ranged from 61.07% (Pampus argenteus) to 86.56% (Tetraodontidae). Meanwhile,total lipid content of fish samples ranged from 1.73% (Tetraodontidae) to 9.82% (Leiognathus equulus). The concentration of α-AminoNitrogen (AN) of fish protein hydrolysate was ranging from 31 mM (Nemipterus hexodon) to 69 mM (Mystacoleucus padangensis)and% Degree of Hydrolysis (DH) was ranging from 9.33% to 20.39%. The molecular weight of protein fish samples had similar profilesprimarily for almost all samples, which could be observed from a typical band with the weight around 49 kDa. The saturated fatty acid(Ʃ SFA) compositions of fish species ranged from 1094.03-4233.03 μg/g. Oleic acid (MUFA) content of all fish species ranged from257.91-1216.06 μg/g. However, only three fish species contain of Poly Unsaturated Fatty Acid (PUFA) linoleic acid as the following;Selaroides leptolepis (171.36 μg/g), Oxyeleotris marmorata (249.40μg/g) and Tetraodontidae (140.35 μg/g). The highest SFA contentwas found in S. leptolepis with palmitic acid (C16:0) as the dominant saturated fatty acid (2320.88 μg/g). S. leptolepis also containedhigh oleic acid (1216.06 μg/g) and linoleic acid (171.36 μg/g).

Abstract The red sunflower seed weevil, Smicronyx fulvus L., is a univoltine seed-feeding pest of cultivated sunflower, Helianthus annuus L. Artificial infestations of S. fulvus onto sunflowers with traditional (<25% oleic acid), mid-oleic (55–75%), or high oleic (>80%) fatty acid profiles were used to test if fatty acids could be used as natural markers to estimate the proportion of weevils developing on oilseed sunflowers rather than wild Helianthus spp. and confection (non-oil) types. Oleic acid (%) in S. fulvus confirmed the fatty acid compositions of mature larvae and weevil adults reflected their diets, making primary (oleic or linoleic) fatty acids feasible as natural markers for this crop-insect combination. Oleic acid in wild S. fulvus populations in North Dakota suggests at least 84 and 90% of adults originated from mid-oleic or high oleic sunflower hybrids in 2017 and 2018, respectively. Surveys in 2017 (n = 156 fields) and 2019 (n = 120 fields) extended information provided by S. fulvus fatty acid data; no significant spatial patterns of S. fulvus damage were detected in samples, damage to oilseed sunflowers was greater than confection (non-oil) types, and the majority of damage occurred in ≈10% of surveyed fields. Combined, data suggest a few unmanaged or mismanaged oilseed sunflower fields are responsible for producing most S. fulvus in an area. Improved management seems possible with a combination of grower education and expanded use of non-insecticidal tactics, including cultural practices and S. fulvus-resistant hybrids.

In order to establish a chemical fingerprint of vanilla diversity, thirty samples of V. planifolia J. W. Moore and V. tahitensis G. Jackson cured beans from seven producing countries were examined for their aroma and fatty acid contents. Both fatty acid and aroma compositions were found to vary between vanilla species and origins. Vanillin was found in higher amounts in V. planifolia (1.7-3.6% of dry matter) than in V. tahitensis (1.0-2.0%), and anisyl compounds were found in lower amounts in V. planifolia (0.05%) than in V. tahitensis (1.4%-2.1%). Ten common and long chain monounsaturated fatty acids (LCFA) were identified and were found to be characteristic of the vanilla origin. LCFA derived from secondary metabolites have discriminating compositions as they reach 5.9% and 15.8% of total fatty acids, respectively in V. tahitensis and V. planifolia. This study highlights the role of the curing method as vanilla cured beans of two different species cultivated in the same country were found to have quite similar fatty acid compositions.

Bryophytes (mosses, liverworts and hornworts) often produce high amounts of very long-chain polyunsaturated fatty acids (vl-PUFAs) including arachidonic acid (AA, 20:4 △5,8,11,14) and eicosapentaenoic acid (EPA, 20:5 △5,8,11,14,17). The presence of vl-PUFAs is common for marine organisms such as algae, but rarely found in higher plants. This could indicate that bryophytes did not lose their marine origin completely when they landed into the non-aqueous environment. Vl-PUFA, especially the omega-3 fatty acid EPA, is essential in human diet for its benefits on healthy brain development and inflammation modulation. Recent studies are committed to finding new sources of vl-PUFAs instead of fish and algae oil. In this review, we summarize the fatty acid compositions and contents in the previous studies, as well as the approaches for qualification and quantification. We also conclude different approaches to enhance AA and EPA productions including biotic and abiotic stresses.

There is evidence that secondary metabolites are involved in the fungal pathogenicity and virulence of Neofusicoccum spp. Fatty acids may also influence the plant–pathogen interaction but, so far, no information is available on their production by species of Neofusicoccum associated with Botryosphaeria dieback, which is a well-known syndrome of several plants with a complex etiology. In the present paper, the production of fatty acids in liquid medium, by strains of N. vitifusiforme and N. parvum associated with declining Sicilian vine plants, was evaluated. Data, acquired via gas chromatography–mass spectrometry (GC/MS), show the presence of linoleic acid as the most abundant fatty acid produced by both examined strains. In addition, the pathogenicity of N. vitifusiforme was tested on 2-year-old grapevine plants of cv. Inzolia.
