γ-linolenic and stearidonic acids from Boraginaceae of diverse Mediterranean origin.
Abstract
Thirty Boraginaceae species from different tribes were evaluated in a search of γ-linolenic (GLA, 18:3 n- 6)- and stearidonic acid (SDA, 18:4 n- 3)-rich oils. The higher GLA percentages were found in the seed oils of Symphytum bulbosum and S. tuberosum subsp. tuberosum (27.6 and 27.2% of total fatty acids (FA)), which are unusual values for GLA-oils in the current literature. On the whole seed, noticeable GLA percentages were found in S. grandiflorum , S. tuberosum subsp. tuberosum and Borago officinalis (7.43, 4.90, and 4.51 g /100 g, respectively). The main SDA-taxa detected in this study were ...

Prospective clinical trial examining the impact of genetic variation in FADS1 on the metabolism of linoleic acid- and ɣ-linolenic acid-containing botanical oils.
CONCLUSIONS: The results of this study clearly suggest that personalized and population-based approaches considering FADS genetic variation may be necessary to optimize the design of future clinical studies with GLA-containing oils. This trial was registered at clinicaltrials.gov as NCT02337231.

Role of peppermint oil in improving the oxidative stability and antioxidant capacity of borage seed oil-loaded nanoemulsions fabricated by modified starch.
Abstract
Borage seed oil (BSO) is one of the richest sources of ??-linolenic acid and linoleic acid, which are considered to retain plenty of health promoting benefits. However, its application in functional foods and dietary supplements remains limited owing to its superior vulnerability to oxidation. To solve this problem, ultrasound-assisted BSO-loaded nanoemulsions were prepared with modified starch incorporating different concentrations of peppermint oil (PO), as a natural antioxidant. The influence of different PO levels on the mean droplet size, rheology attributes, and oxidative stability of nanoem...

A systematic review and quality assessment of case reports of adverse events for borage (Borago officinalis), coltsfoot (Tussilago farfara) and comfrey (Symphytum officinale).
CONCLUSION: These cases are an unreliable body of evidence on which to draw conclusions about oral consumption of Symphytum officinale and Tussilago farfara. With insufficient evidence to differentiate the relative risk of one PA-containing plant from another; toxicological studies based on oral ingestion of phytochemically complex preparations of these herbs may be the most accurate methodology for assessing clinical risk.

Borage, camellia, centaurea and pansies: nutritional, fatty acids, free sugars, vitamin E, carotenoids and organic acids characterization
Publication date: Available online 4 February 2020Source: Food Research InternationalAuthor(s): Luana Fernandes, Elsa Ramalhosa, José Alberto Pereira, Jorge Alexandre Saraiva, Susana CasalAbstractThe present study aimed to evaluate the nutritional and bioactive potential of four edible flowers (borage, centaurea, camellia, and pansies). Significant differences were observed among the four. Water was the main constituent (>76%, fresh weight - fw). Linoleic and palmitic acids were the major fatty acids found in borage and red and yellow pansies, while in camellia it was the arachidic acid. In white pansies, behenic and arac...

Improvement of thermal stability and antioxidant activity of anthocyanins of Echium amoenum petal using maltodextrin/modified starch combination as wall material.
Abstract
To protect anthocyanins of Iranian borage extract (IBE) by encapsulation, maltodextrin (MD)/modified maize starch (MMS) combinations were used at four ratios (MD/MMS: 1/0, 1/0.25, 1/0.5, 1/1, w/w%). The microencapsulated powders with different ratios of wall material presented encapsulation efficacy between 93.1 and 97.4%. FTIR confirmed the cross-linking interaction between extract and MD/MMS wall. Increased thermal stability of extract was also indicated by DSC analysis. The stability of microstructures and crude extract at two conditions (5 and 40 °C) was evaluated by UV and HPLC methods dur...

Independent evolution of rosmarinic acid biosynthesis in two sister families under the Lamiids clade of flowering plants [Metabolism]
As a means to maintain their sessile lifestyle amid challenging environments, plants produce an enormous diversity of compounds as chemical defenses against biotic and abiotic insults. The underpinning metabolic pathways that support the biosynthesis of these specialized chemicals in divergent plant species provide a rich arena for understanding the molecular evolution of complex metabolic traits. Rosmarinic acid (RA) is a phenolic natural product first discovered in plants of the mint family (Lamiaceae) and is recognized for its wide range of medicinal properties and potential applications in human dietary and medical int...

The effects of dietary fatty acids on bone, hematopoietic marrow and marrow adipose tissue in a murine model of senile osteoporosis.
Conclusion: Feeding FO-enriched diet prevented age-related bone and HBM loss, by reducing MAT expansion. Our results further emphasize on the role(s) of MAT expansion in bone and HBM atrophy.Methods: SAMP8 mice (n>9 /group) were allocated into 4 categories and fed a control ration, FO-, sunflower oil (SFO)- and borage oil-enriched diets for lifetime. Femurs were scanned using microcomputed tomography (μCT) and bone, MAT, and HBM volumes were determined using an image analysis software.

Attraction of green lacewings (Neuroptera: Chrysopidae) to native plants used as ground cover in woody Mediterranean agroecosystems
Publication date: Available online 8 August 2019Source: Biological ControlAuthor(s): Rafael Alcalá Herrera, Francisca Ruano, Cándido Gálvez Ramírez, Stephanie Frischie, Mercedes CamposAbstractUsing native seeds to establish semi-natural habitats is a novel strategy to restore biodiversity and ecosystem services such as biological control. As green lacewings (Neuroptera: Chrysopidae) are regarded as major biological control agents in different crops, the objective of this study was to test the attractiveness of selected native plant species to lacewings. During a two-year (2016-2017) field experiment near Villarrubia (A...

Lipid emulsions for parenterally fed preterm infants.
CONCLUSIONS: In the current review, we did not find any particular LE with or without fish oil to be better than another LE in preterm infants for prevention of PNALD/cholestasis, growth, mortality, ROP, BPD and other neonatal outcomes.In preterm infants with surgical conditions or cholestasis, there is currently insufficient evidence from randomised studies to determine with any certainty if fish oil LEs offer advantage in prevention or resolution of cholestasis or in any other clinical outcome.Further research, with larger well-designed trials, is warranted to evaluate the ideal composition of LE in preterm infants and t...

Lipid emulsions for parenterally fed term and late preterm infants.
CONCLUSIONS: Based on the current review, there is insufficient data from randomised studies to determine with any certainty, the potential benefit of any LE including fish oil-containing LEs over another LE, for prevention or resolution of PNALD/cholestasis or any other outcomes in term and late preterm infants with underlying surgical conditions or cholestasis. There were no studies in infants without surgical conditions or cholestasis.Further research is required to establish role of fish oil or lipids from other sources in LEs to improve PNALD/cholestasis, and other clinical outcomes in parenterally fed term and late p...
