Seed oils of 18 species of Aceraceae (maple family) were examined and their fatty acid compositions were determined. Those of all but one species had substantial amounts of C20, C22, and C24cis-monoenoic acids. Acer rubrum, typical of the group, had 7% eicosenoic, 13% docosenoic, and 4% tetracosenoic acid in the total fatty acids of its oil. The chief isomers, identified in the oil of A. saccharum, were cis-11-eicosenoic, cis-13-docosenoic, and cis-15-tetracosenoic acids. The oils of Dipteronia sinensis and Acer negundo were much like the other Acer oils in composition, but that of A. saccharinum was composed almost entirely of the ordinary C16 and C18 fatty acids. The results are discussed in relation to the taxonomy of the family.

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.

We have investigated growth of ectomycorrhizal (ECM) fungi (i.e., 55 strains of 32 species in 15 genera) on saturated (palmitate), monounsaturated (oleate), diunsaturated (linoleate), triunsaturated (linolenate) fatty acids, and the triacylglyceride of oleate (triolein) lipid to elucidate an ability to utilize the fatty acids and lipid as a carbon source for growth. Relative utilization ratios (URs, %) based on mycelial growth on glucose suggest that ECM fungi belonging to the family Thelephoraceae have an ability to utilize palmitate. On the other hand, ECM fungi in the genus Laccaria can utilize at least either palmitate or oleate. Furthermore, Hygropharus russula grows on palmitate, oleate, and slightly on triolein. Lactarius chrysorrheus grows only on palmitate. These fatty-acid- and lipid-utilizing fungi may be promising as model fungi for further elucidation of the metabolic ability to utilize the fatty acids and lipid as a carbon source. On the contrary, the fungi in the genus Suillus were shown to scarcely utilize the fatty acids and lipid. Furthermore, most ECM fungi did not grow on either linoleate or linolenate.Key words: carbon source, ectomycorrhizal fungi, fatty acid, lipid, mycelial growth.

The total lipid content of eight species of nuts available in Hangzhou ranged from 49.5 g/100 g weight in Cannabis sativa to 75.4 g/100 g in walnut. The predominant content of lipid is triacylglycerol, ranging from 91.1% in Cannabis sativa to 98.4% in macadamia. There were two polyunsaturated fatty acids (PUFA) in all nuts analyzed; 18:2n-6 and 18:3n-3. The content of 18:3n-3 ranging from 0.2% in almond to 15.2% in Cannabis sativa, 18:2n-6 ranged from 2.5% in macadamia to 61.6% in pine nut. The proportion of total PUFA in analyzed eight nut species ranging from 2.8% in macadamia to 71.7% in walnut (p < 0.001). Monounsaturated fatty acid composition ranged from 18.0% in Cannabis sativa to 82.6% in macadamia (p < 0.001). The proportion of saturated fatty acid ranged from 7.4% in filbert to 14.7% of total fatty acids in macadamia (p < 0.001). No C20 fatty acids were detected in any of the samples in the present study. The lipids content and fatty acid compositions in analyzed samples were varied between nut species. Cannabis sativa and walnut contained relatively high 18:3n-3, consumption of several these nuts each day can contribute to n-3 PUFA intake, especially for the vegetarian population.

This paper reports the physicochemical characteristics of the seed oils from different varieties of passion fruit (Passiflora alata Curtis, Passiflora edulis f. flavicarpa and Passiflora quadrangularis) cultivated in Brazil, Roraima. The oil  from passion fruit, within the range of 19.29±0.02; 21.34±0.22 e 14.24±0.16%, respectively. The physicohemical characteristics of the extracted oils were: free fatty acid contents (0.84±0.01 - 2.73±0.05 % mg KOH g-1 as oleic acid), iodine value (101.63±0.18 - 125.96±0.13 g of I2 100 g-1 of oil), and saponification index (90.56±0.32 - 179.06±0.19 mg KOH g-1 of oil). The oils revealed a reasonable oxidative parameter range as depicted by the determinations of index peroxide value (1.92±0.09 – 3.05±0.03 meqO2 kg-1 of oil). Linoleic acid was the major fatty acid found in all the seed oils with contributions of 55.75-63.42% of the total fatty acids (FA). Other fatty acids detected were known to be oleic acid (19.3-20.1%), palmitic acid (10.8-12.8%) and stearic acid (3.25-4.25%). Through the DPPH test we observed the presence of antioxidants in the three oil samples. The results of the present study indicate that the seeds of the tested passion fruit varieties from Roraima are a potential source of high-linoleic oil and thus can be explored for commercial use and value addition.

In the present study, the fatty acid compositions, vitamin, sterol contents and flavonoid constituents of five Turkish Artemisia species (A. armeniaca, A. incana , A. tournefortiana, A. haussknechtii and A. scoparia) were determined by GC and HPLC techniques. The results of the fatty acid analysis showed that Artemisia species possess high saturated fatty acid compositions. On the other hand, the studied Artemisia species were found to have low vitamin and sterol contents. Eight flavononids (catechin, naringin, rutin, myricetin, morin, naringenin, quercetin, kaempferol) were determined in the present study. It was found that Artemisia species contained high levels of flavonoids. Morin (45.35 ± 0.65 – 1406.79 ± 4.12 μg/g) and naringenin (15.32 ± 0.46 – 191.18 ± 1.22 μg/g) were identified in all five species. Naringin (268.13 ± 1.52 – 226.43 ± 1.17 μg/g) and kaempferol (21.74 ± 0.65 – 262.19 ± 1.38 μg/g) contents were noted in the present study. Present research showed that the studied Artemisia taxa have high saturated fatty acids and also rich flavonoid content.

The long-chain polyene (LCP) status of thirty-nine premature infants (birth weight < 1800 g) was evaluated. Twenty-seven infants were fed on an artificial formula, twelve received their own mother's breast milk. Fatty acid compositions of both plasma and erythrocyte (RBC) phospholipids (PL) were determined in umbilical venous blood and in weekly postnatal blood samples until the 28th day of life. Individual fatty acid levels were expressed as absolute quantities (mg fatty acid/I plasma or RBC suspension) and as relative (mg/100 mg total fatty acids) values. The changes with time in the absolute values for 22:6n-3 and 20:4n-6 in plasma were strikingly different from those of the relative values for these fatty acids. In plasma PL the inter-group differences in the absolute postnatal values for 22:6n-3 (P < 0·0005) and 20:4n-6 (P < 0·05) and the relative values for 22:6n-3 (P < 0·02) were significant, with lower fatty acid values in the formula-fed infants. In RBC PL, no significant inter-group differences in the postnatal 22: 6n-3 and 20: 4n-6 values were found. Based on the assumption that it is desirable for formula-fed infants to achieve postnatal plasma LCP values at least comparable with those found in infants fed on human milk, the findings of the present study indicate that both n-3 and n-6 LCP should be added to preterm infant formulas. Moreover, the additional importance of absolute fatty acid levels was demonstrated, although analytical procedures need to be standardized to enable effective comparison of results from different research groups.

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.

The fatty acid compositions of the lipids of two holothurian species ( Cucumaria japonica and C. okhotensis) were investigated. High contents of 12-methyltetradecanoic acid and eicosapentaenoic acid (up to 17.7 % and 28.4% of total fatty acids, respectively) in the lipids of both species were revealed. Species specific differences in the content of 23:1 n-9 fatty acid in the lipids from viscera and body wall were found. In C. japonica, the viscera to body wall ratio was 0.07, while in C. okhotensis this ratio was 0.28. The fatty acid compositions of the lipids from both investigated holothurian species permit their use for the manufacturing of foodstuff, as well as for biologically active additives.

Lipid classes and fatty acid compositions of the farmed (F-C. gigas) and wild (W-C. gigas) pacific oysters, Crassostrea gigas, in Nha Trang, Vietnam were investigated for the first time. The results indicated that the lipid classes and fatty acid components of these oysters were insignificantly different. The total lipid of both studied oysters included six lipid classes, namely phospholipid (PL), sterol (ST), free fatty acid (FFA), triacylglycerol (TG), monoalkyldiacylglycerol (MADG), and hydrocarbon-wax (HW) in which TG and PL were dominated with the values of 48.4%, 41.8% for TG and 19.0%, 20.3% for PL in F-C. gigas and W-C. gigas, respectively. The fatty acids (FAs) content of F-C. gigas and W-C. gigas was similar. The saturated fatty acids (SFAs) content was 48.2% in total fatty acids (TFAs) of the F-C. gigas and 44.7% in TFAs of W-C. gigas, in which 16:0 was dominated in SFAs of both oysters with the value of 24.2% in F-C. gigas and 22.0% in W-C. gigas. The contents of monounsaturated fatty acids (MUFAs) and polyunsaturated fatty acids (PUFAs) were 18.3%, 20.5% for MUFAs and 31.7%, 34.7% for PUFAs respectively in F-C. gigas and W-C. gigas. These MUFAs compositions contained 16:1n-7, 16:1n-5, 18:1n-9, 18:1n-7, 20:1n-11, 20:1n-9 and 20:1n-7, among them fatty acids 16:1n-7 (7.2% in F-C. gigas, 6.3% in W-C. gigas) and 18:1n-7 (6.6% in F-C. gigas, 7.4% in W-C. gigas) were the main MUFAs. PUFAs in these two oysters consisted of long-chain n-3 and n-6 fatty acids, in which 20:5n-3 (EPA) and 22:6n-3 (DHA) were dominated with the values of 12.7%, 13.9% for EPA in F-C. gigas and 6.5%, 6.0% for DHA in W-C. gigas.
