Screening of Lesser-Known Salted-Dried Fish Species for Fatty Acids, Tocols, and Squalene.

The fillets and roes of 29 species of dry-salted fishes consumed in Eurasian countries were analyzed for fatty acids (FAs), tocols, and squalene, looking for derived health benefits. FAs were analyzed by GC-FID, and tocols and squalene were analyzed by HPLC-DAD. With some exceptions, docosahexaenoic (DHA, 22:6-3), eicosapentaenoic (EPA, 20:5-3), and arachidonic (ARA, 20:4-6) acids were the prominent polyunsaturated fatty acids (PUFAs).

Arecaceae Seeds Constitute a Healthy Source of Fatty Acids and Phenolic Compounds.

Seeds of most Arecaceae species are an underutilized raw material that can constitute a source of nutritionally relevant compounds. In this work, seeds of 24 Arecaceae taxa were analyzed for fatty acids (FAs) by GC-FID, for phenolics by HPLC-DAD and LC-MS, and for their antitumor activity against the HT-29 colorectal cancer cell line by the MTT assay. Lauric, oleic, and linoleic acids were the prominent FAs.

Fatty acid profiling in the genus Pinus in relation to its chemotaxonomy and nutritional or pharmaceutical properties.

To develop and utilize the oil of Pinus seeds and explore natural resources rich in pinolenic acid (PNLA), twenty-one Pinus taxa were evaluated in a search of Δ5-unsaturated polymethylene-interrupted fatty acids (Δ5-UPIFA)-rich oils. While the fatty acid (FA) composition was determined by GC-FID and GC-MS, NMR of crude oils proved to be a fast method for establishing the ratio between Δ5-UPIFA and total FA. For all analyzed taxa, both the geographical origin and the concentration of total FA in the seeds are provided.

Buglossoides spp. seeds, a land source of health-promoting n-3 PUFA and phenolic compounds.

Ahiflower oil© is extracted from the seeds of Buglossoides arvensis, which contains high amounts of stearidonic acid (SDA, 18:4n-3), while its phenolic composition still is unreported. Moreover, several Buglossoides taxa remain unstudied and could become natural sources of SDA. In this work, seeds of several Buglossoides taxa and Ahiflower oil© were screened for fatty acids, phenolic compounds, and in vitro antiproliferative activities against colorectal cancer cells.

Gamma-linolenic Acid from Fifty-seven Ribes Species and Cultivars.

γ-linolenic acid (GLA, 18:3n-6) is a bioactive fatty acid (FA) that exerts several healthy actions; however, its occurrence is restricted to a few oils. The goal of this study was to detect GLA-rich Ribes species and cultivars (cv), and to achieve this the seeds of 7 Ribes taxa and 50 Ribes cv were surveyed for FA profiles. The highest GLA percentages were found in R.

LED Enhances Plant Performance and Both Carotenoids and Nitrates Profiles in Lettuce.

Recent studies show that vegetables at early stage of development contain higher amounts of phytonutrients and minerals, and lower amounts of nitrates than at fully developed stage. Nevertheless, the effects of some spectrum light on the carotenoid content of lettuce microgreens are unknown. Three different LED lamps were checked: (i) artificial white light (T); (ii) continuous light-emitting diodes with longer blue-wavelength (T), and (iii) continuous light-emitting diodes with longer red-wavelength (T).

Mertensia (Boraginaceae) seeds are new sources of γ-linolenic acid and minor functional compounds.

In this work, seeds from selected Mertensia species were analyzed for γ-linolenic acid-rich oils and minor functional compounds. Fatty acids (FA) were analyzed by GC-FID; tocopherols, sterols, squalene, and phenolics compounds by HPLC-DAD, and the structures of the latter were confirmed by LC-MS. M.

γ-Linolenic and Stearidonic Acids from Boraginaceae of Diverse Mediterranean Origin.

Thirty Boraginaceae species from different tribes were evaluated in a search of γ-linolenic (GLA, 18:3n-6) and stearidonic acid (SDA, 18:4n-3)-rich oils. The high GLA percentages were found in the seed oils of Symphytum bulbosum and S. tuberosum subsp.

Ribes taxa: A promising source of γ-linolenic acid-rich functional oils.

Fifty Ribes species and R. nigrum-based cultivars from eight Ribes sections were surveyed for γ-linolenic acid (GLA, 18:3, n-6)- and stearidonic acid (SDA, 18:4, n-3)-rich oils. R.
