The composition of hydro-distilled essential oils of Phlomis anisodonta Boiss. subsp. occidentalis Jamzad in vegetative, flowering and post flowering stages were investigated using GC and GC-MS, leading to identification of 41, 26 and 23 compounds, respectively. In all three samples, sesquiterpenes were the main components. In vegetative stage the main components of the oil were germacrene-D (1...

This study was outlined to examine the chemical composition of hydrodistilled essential oil and in vitro antioxidant potentials of the essential oil and different solvent extracts of endemic Phlomis bourgaei Boiss. used as folk remedy in Turkey. The chemical composition of the oil was analyzed by GC and GC-MS, and the predominant components in the oil were found to be β -caryophyllene (37.37%),...

This study represents the first report on the chemical composition and biological activity of Trifolium angustifolium var. angustifolium. The major components of the essential oil were identified as hexatriacontene (23.0%), arachidic acid (15.5%) and α-selinene (10.0%). The main constituents of the fatty acid obtained from the petroleum ether extract were identified as palmitic acid (29.8%), li...

The antioxidative activity of α-tocopherol and Trolox, a water-soluble carboxylic acid derivative of α-tocopherol, in an emulsion stabilized with the hydrophilic emulsifier, polyoxyethylene (20) sorbitan monolaurate, was evaluated by measuring the changes in linoleic acid content, peroxide value, and thiobarbituric acid value. The activity of α-tocopherol and Trolox to depress the autoxidation ...

Two major carotenoids of the stick insect were reinvestigated and shown to be /?,/?-caroten-2-ol and /?,/?-carotene-2,2'-diol and not isocryptoxanthin (/?,/?-caroten-4-ol) and isozeaxanthin (/?,/?-carotene-4,4'-diol). Both pigments are esterified with fatty acids. The identification is based on cochromatography with authentic 2-, 3and 4-isomers of the monoand dihydroxy pigment, mass spectra, an...

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%...

Background: For understanding the roles of fatty acids on the induction of acrosome reaction which occurs under association of cholesterol efflux and PKA or PKC pathways in boar spermatozoa, metabolic fate of alone and combined radiolabeled 14C-oleic acid and 3H-linoleic acid incorporated in the sperm was compared, and behavior of cholesterol and effects of PKA and PKC inhibitors upon fatty aci...
