The essential oil obtained from the aerial parts of Marrubium deserti de Noé. (Lamiaceae), growing in the North fringe of the Algerian Sahara, was analyzed by GC-MS. Thirty-eight compounds were identified, representing 99.70% of the total oils. The GC-MS analysis revealed the presence of tetracosane, germacrene D, Δ-cadinene, α-cadinol and t-cadinol as the main constituents, representing 31.11%...

The essentiality of the n-6 fatty acid, linoleic acid, was established about 80 years ago; the essentiality of the n-3 analogue, a-linolenic acid, became accepted rather later. The intakes of these fatty acids necessary to avoid deficiency are quite low (estimated to be 1 and 0·2 % of energy intake, respectively, corresponding to intakes in adults of about 2 and 0·4 g/d), and all diets should o...

Bitter melon (Colocynth) is a species of herbs, annual medicinal plant of family Cucurbitaceae which are mainly grown in warm regions of Iran. Fatty acids of the seeds of this plant are considered as important materials, medicinally. In this study, essential fatty acids of seed collected from nine different regions of Iran were evaluated. The composition of fatty acids such as oleic, linoleic, ...

The metabolism of the linolenic acid family (n-3) of fatty acids, e.g., linolenic, eicosapentaenoic, and docosahexaenoic acids, in cultured smooth muscle cells from rabbit aorta was compared to the metabolism of linoleic and arachidonic acids. There was a time-dependent uptake of these fatty acids into cells for 16 hr (arachidonic greater than docosahexaenoic, linoleic, eicosapentaenoic greater...

The hydrogenation of all the methylene-interrupted cis,cis-octadecadienoic acids was examined using pure cultures of six rumen bacteria able to hydrogenate linoleic acid to stearic acid or its immediate precursor, trans-11-octadecenoic acid, after first conjugating the linoleic acid to cis,trans-9,11-octadecadienoic acid. Only the delta 14-cis,17-cis-isomer was not hydrogenated by at least one ...

1. The effects of unsaturated fatty acids on drug-metabolizing enzymes in vitro were measured by using rat and rabbit hepatic 9000g supernatant fractions. 2. Unsaturated fatty acids inhibited the hepatic microsomal metabolism of ;type I' drugs with inhibition increasing with unsaturation: arachidonic acid>linolenic acid>linoleic acid>oleic acid. Inhibition was independent of lipid peroxidation....

Department of Botany & Microbiology, Gurukul Kangri University Haridwar 249404, Uttarakhand, India ABSTRACT: Lipstatin, a new and very potent inhibitor of pancreatic lipase, was isolated from the Streptomyces toxytricini. Lipstatin contain a beta lactone structure that probably account for the irreversible lipase inhibition. As per the biosynthetic pathway the role of linoleic acid, palmitic ac...

An endogenous inhibitor of the in vitro binding of the phytotropin N-1-naphthylphthalamic acid to microsomal membranes was detected in extracts prepared from etiolated pea (Pisum sativum L.) epicotyls. Following extensive purification, the inhibitor was identified as linoleic acid. Authentic linoleic acid inhibited N-1-naphthylphthalamic acid binding noncompetitively in a dose-dependent manner,...

Background: Cassia absus L. and Citrus medica plants are sources of different phytochemicals with pharmaceutical significance. They biochemically distinctive used in producing various herbal products exclusive bioactivity. Also, the extraction these phytonutrients medicinal characteristics has recently increased. Objectives: We determined to evaluate plant-derived compounds such as polyphenols ...

Previous studies have shown that the quantity of oxidized lipids in the diet directly correlates with the level of oxidized chylomicrons in mesenteric lymph and the level of oxidized lipids in endogenous lipoproteins such as very low density lipoprotein (VLDL) and low density lipoprotein (LDL). The aim of the present study was to determine whether oxidized fatty acids in the diet are delivered ...
