Laurus nobilis, Zingiber officinale and Anethum graveolens Essential Oils: Composition, Antioxidant and Antibacterial Activities against Bacteria Isolated from Fish and Shellfish
TL;DR: Low concentrations of the three essential oils were needed to inhibit the growth of the selected bacteria and the lowest MBCs values were obtained for the laurel essential oil.
Journal ArticleDOI
Supercritical fluid extraction of antioxidant and antimicrobial compounds from Laurus nobilis L. Chemical and functional characterization
TL;DR: Most of the compounds identified in the supercritical extract have been previously described to show antimicrobial activity; among them, the major compound found in thesupercritical extract corresponded to a sesquiterpene lactone of the germacrolide type (6-epi-desacetyllaurenobiolide) previously described in laurel.
Chemical Composition, Radical Scavenging and Antimicrobial Activity of the Essential Oils of Thymus boveii and Thymus hyemalis
TL;DR: Both plant species showed remarkable antioxidant activity in all test systems except chelating effect and in the case of antimicrobial activity, the oils showed remarkable growth inhibition against the tested microorganism except K. pneumoniae.
Journal ArticleDOI
Volatile constituents of the leaves and flowers of Hypericum triquetrifolium Turra
TL;DR: In this article, the major components identified in each oil were n-nonane (8, 15%), β-pinene, β-caryophyllene, sabinene and myrcene, respectively.
Journal ArticleDOI
Composition and antimicrobial activity of the essential oil of Achillea falcata L. (Asteraceae)
TL;DR: The composition of the essential oil from aerial parts of Achillea falcata L. (Asteraceae) growing wild in Lebanon was analyzed by GC and GC-MS; 58 compounds, representing 94.4% of the oil, were identified.

A generalization of the retention index system including linear temperature programmed gas-liquid partition chromatography.
H. van Den Dool,P. Dec. Kratz +1 more
TL;DR: The equation given by Kovats for the calculation of the retention index in case of isothermal operation is transformed to a more general form to include also the case of linear temperature programmed operation and gives the same retention index for both ways of operation.

Gas‐chromatographische Charakterisierung organischer Verbindungen. Teil 1: Retentionsindices aliphatischer Halogenide, Alkohole, Aldehyde und Ketone
TL;DR: In this article, a simple relation exists between the retention index of a compound on a non-polar stationary phase and its boiling point, which is defined as the ratio of the boiling point of the compound to its retention index.

The identification of sesquiterpene hydrocarbons from gas-liquid chromatography retention data
TL;DR: In this article, the identification of sesquiterpenes by gas-liquid chromatography was evaluated, and the most reproducible form of GLC data was found to be the SESQUERPene data.
