Erich Schmidt,Leopold Jirovetz,Gerhard Buchbauer,Gernot A. Eller,Ivanka Stoilova,Albert Krastanov,Albena Stoyanova,Margit Geissler +7 more
TL;DR: The composition of the volatiles from leaves of Cinnamomum zeylanicum Blume from Sri Lanka was studied by GC-FID and GC-MS as mentioned in this paper.
Journal ArticleDOI
Gastric antiulcer effect of Rhizophora mangle L.
TL;DR: The effects of the freeze-dried aqueous extract from red mangrove bark on gastric ulceration induced by ethanol-hydrochloric acid were studied in rats and showed no effect on the mucus secretion induced in this experimental model.

Essential oils of wild and cultivated carrots : the chemical composition and antimicrobial activity
TL;DR: The oils obtained from cultivated carrot seed were more effective against all tested organisms and the strongest overall activity was demonstrated by the commercial oil of cultivated carrot seeds.
Journal ArticleDOI
Volatile secondary metabolites from Spilanthes americana obtained by simultaneous steam distillation-solvent extraction and supercritical fluid extraction
TL;DR: In this article, secondary volatile metabolites were isolated by simultaneous distillation-solvent extraction (SDE) and supercritical (CO2) extraction from flowers, leaves and stems of Spilanthes americana.
Journal ArticleDOI
Insecticidal Activities of the Leaf Oils of Eight Cinnamomum. species Against Aedes aegypti. and Aedes albopictus.
TL;DR: It is suggested that the essential oils containing high levels of benzyl benzoate and benzyl salicylate exhibited strong insecticidal activities against the larvae and adult mosquitoes.

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.
