the objective of the present study was to determine the antilipidperoxidation and in vitro α-amylase and lipase inhibitory activity of the boswellia ovalifoliolata bal henry (bob) extract. the polyphenolic compounds, flavonoids, and tannins content of the extracts were estimated by spectrophotometry. antioxidant activity on goat liver lipid peroxidation and linoleic acid was determined.moreover...

Acetonitrile chemical ionization tandem mass spectrometry has recently been shown to be a rapid method for the identification of double-bond position and geometry in methyl esters of conjugated linoleic acids (CLAs); however, the structures of intermediate and diagnostic ions and their mechanisms of formation are not known. A mechanism is proposed here in which the m/z 54 ion, (1-methyleneimino...

Lipids were extracted from alfalfa samples collected at intervals over the growing season and were fractionated to yield pure sulfolipid. In the sulfolipid and in a phospholipid fraction the major fatty acids were palmitic, linolenic, and linoleic, of which the palmitic acid increased in proportion during the season while the proportion of linolenic acid dropped. The sulfolipid contained more l...

A survey of 30 representative strains of human gram-positive intestinal bacteria indicated that Roseburia species were among the most active in metabolizing linoleic acid (cis-9,cis-12-18:2). Different Roseburia spp. formed either vaccenic acid (trans-11-18:1) or a 10-hydroxy-18:1; these compounds are precursors of the health-promoting conjugated linoleic acid cis-9,trans-11-18:2 in human tissu...

Xylaria, belonging to the Ascomycotina, is known to produce diverse classes of bioactive substances. In an effort to identify the chemical constituents of the fruiting bodies of Xylaria polymorpha, linoleic acid (1), linoleic acid methyl ester (2), ergosterol (3), 4-acetyl-3,4-dihydro-6,8-dihydroxy-3-methoxy-5-methyl-1H-2-benzopyran-1-one (4), and 4-hydroxyscytalone (5) were isolated from its m...

Conjugated linoleic acid (CLA) is a class of 28 positional and geometric isomers of linoleic acid octadecadienoic.Currently, it has been described many benefits related to the supplementation of CLA in animals and humans, as in the treatment of cancer, oxidative stress, in atherosclerosis, in bone formation and composition in obesity, in diabetes and the immune system. However, our results show...

Conjugated linoleic acid (CLA) and CLA isomers, present naturally in dairy meat products, are the natural functional components. Ruminal microorganisms, such as Butyrivibrio fibrosolvens, lactic bacteria (LAB), propionibacteria can convert (LA) to CLA. In this study, effect of different concentrations (0, 0.5, 1, 2%) storage time 2, 7, 14 21 days) on content kefir was investigated. The highest ...

The objective of this study was to assess the effect of conjugated linoleic acid isomers (CLAs) on the expression and activity of phospholipases A(2) (PLA(2)) in human macrophages. Macrophages were incubated with 30 microM cis-9, trans-11 and trans-10, cis-12 CLAs for 48 h. After incubation, the total activity of phospholipases as well as the expression of mRNA for cytosolic (cPLA(2)) and secre...

Increased Milk Production, Concentration of Unsaturated Fatty Acids and Conjugated Linoleic Acid in the Holstein Lactating Cows using Monensin

Linoleic acid is the main PPAR ligand in white button mushrooms and may be involved their anti-obesogenic effect.
