The fixed oil of L. usitatissimum (flaxseed/linseed) inhibited PGE2-, leukotriene-, histamine- and bradykinin-induced inflammation. The oil also inhibited arachidonic acid-induced inflammation, suggesting its capacity to inhibit both cyclooxygenase and lipoxygenase pathways of arachidonate metabolism. In tail immersion model, the oil raised the pain threshold to a lesser extent than morphine bu...

Oil-in-water (O/W) nanoemulsions formed from bioactive compounds such as polyunsaturated fatty acids (PUFA), are commercially attractive because of the potential health benefits associated with their consumption. Emulsions with a mean droplet size as small as 72±5.14 nm and viscosity 3.84±0.26 mPa·s were achieved using a mixture of 10:100 (V/V) linseed oil and water in the presence of surfactan...

Flax (Linum usitatissimum L.) seeds are widely used for oil extraction and the cold-pressed flaxseed (or linseed) cakes obtained during this process constitute a valuable by-product. The flavonol herbacetin diglucoside (HDG) has been previously reported as a constituent of the flaxseed lignan macromolecule linked through ester bonds to the linker molecule hydroxymethylglutaric acid. In this con...

Previous studies reported low benznidazole (BNZ) loading in conventional emulsions due to the weak interaction of the drug with the most common oils used to produce foods or pharmaceuticals. In this study, we focused on how the type of surfactant, surfactant-to-oil ratio w/w (SOR) and oil-to-water ratio w/w (OWR) change the phase behavior of different lipid-based drug delivery systems (LBDDS) p...

OBJECTIVE To determine essential fatty acid concentrations in plasma and tissue before and after supplementation with n-3 fatty acids in dogs with atopic dermatitis. ANIMALS 30 dogs with atopic dermatitis. PROCEDURE Dogs received supplemental flaxseed oil (200 mg/kg/d), eicosapentaenoic acid (EPA; 50 mg/kg/d)-docosahexaenoic acid (DHA; 35 mg/kg/d), or mineral oil as a placebo in a double-bl...

Flaxseed (Linum usitatissimum) meal, the main byproduct of the flaxseed oil extraction process, is composed mainly of proteins, mucilage, and phenolic compounds. The extraction methods of phenolics either commonly employed the use of mixed solvents (dioxane/ethanol, water/acetone, water/methanol, and water/ethanol) or are done with the aid of alkaline, acid, or enzymatic hydrolysis. This work a...

Flaxseed is being consumed as an ingredient in various food formulations as it plays a major role in the field of diet and disease research due to its potential health benefits associated with linolenic acid (57%) and its rich phytoestrogens or lignans. Hence, presently, it is in great demand by food industries and in nutraceutical applications. The present study was carried out using 80, 32-w...

Vegetable oils present important pharmacological properties, which gained ground in the pharmaceutical field. Its encapsulation in nanoemulsions is considered a promising strategy to facilitate the applicability of these natural compounds and to potentiate the actions. These formulations offer several advantages for topical and systemic delivery of cosmetic and pharmaceutical agents including c...

A new technology for the encapsulation of lipophilic molecules -both drugs and contrast agentshas been developed, based on oil-in-water nanoemulsions. Physicochemical characterizations of the nanoparticles evidence highly stable lipid nanoemulsions with amorphous core of temperatureand compositiontunable viscosity. Particles display low in vitro cytotoxicity (IC50 > 300 μg/mL of lipids), and hi...
