Chemical composition and biological activities of the essential oil from Artemisia herba-alba growing wild in Tunisia.
Ismail Amri,Laura De Martino,Aurelio Marandino,Hamrouni Lamia,Hanana Mohsen,Elia Scandolera,Vincenzo De Feo,Emilia Mancini +7 more
TL;DR: The chemical composition of the oil of A. herba-alba can help in the chemosystematics of this complex genus, however, the recorded biological activities seem to be neither ecologically nor medicinally significant.
Journal ArticleDOI
Essential Oil of Nigella damascena L. (Ranunculaceae) Seeds
TL;DR: The chemical composition of the essential oil of Nigella damascena L. seeds, collected from fruiting plants in their natural habitat, was examined in comparison with commercial seeds and the alkaloids were damascenine and methyl 2-amino-3-methoxy benzoate, the latter being detected for the first time in this species.

Compositional characteristics and aromatic profile of date palm seeds from seven varieties grown in Tunisia
Emna B. SaafiâBen Salah,Guido Flamini,Amira El Arem,Manel Issaoui,Samia Dabbou,Leila Ben-Yahia,Ali Ferchichi,Mohamed Hammami,Lotfi Achour +8 more
TL;DR: In this paper, a discrimination study based on the physico-chemical characteristics, fatty acids and profile of volatile compounds of the seeds from seven date palm varieties (Phoenix dactylifera L.) grown in Tunisia was performed.

Rapid prediction of deoxynivalenol contamination in wheat bran by MOS‐based electronic nose and characterization of the relevant pattern of volatile compounds
Vincenzo Lippolis,Salvatore Cervellieri,Anna Damascelli,Michelangelo Pascale,Annalisa Di Gioia,Annalisa Di Gioia,Francesco Longobardi,Annalisa De Girolamo +7 more
TL;DR: The results indicate that the e-nose method could be a useful tool for high-throughput screening of DON-contaminated wheat bran samples for their classification as acceptable / rejectable at contamination levels close to the EU maximum limit for DON.

Essential oil constituents of Eclipta prostrata (L.) L. and Vernonia amygdalina Delile
TL;DR: The chemical composition of the essential oils from the leaves and stem bark of Eclipta prostrata (L.) L. and the aerial parts of Vernonia amygdalina Delile (Asteraceae) have been analyzed by capillary gas chromatography/mass spectrometry and the investigation led to the identification of 33 and 30 compounds.

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.
Journal ArticleDOI
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.
