Composition of Leaf, Fruit and Gall Essential Oils of Algerian Pistacia atlantica Desf.
TL;DR: Essential oils from leaves, fruits and galls of P. atlantica, analyzed by GC/FID, GC/MS and 13C-NMR, were dominated by monoter-pene hydrocarbons, α-pinene (32.6–54.7%) and β- pinene (8.0–20.2%) being the major components.

Rapid identification of volatile compounds in aromatic plants by automatic thermal desorption — GC-MS
TL;DR: In this paper, the application of automatic thermal desorption coupled to GC-MS to the identification and characterization of volatile components of plants of different families is given, of special interest for plant species whose composition has not been previously studied.

Classification of essential oil composition in Rosa damascena Mill. genotypes using an electronic nose
Abbas Gorji-Chakespari,Ali Nikbakht,Fatemeh Sefidkon,Mahdi Ghasemi-Varnamkhasti,Eduard Llobet Valero +4 more
TL;DR: In this article, an electronic nose (EN) system was designed based on metal oxide semiconductor (MOS) sensors, and trained to identify the categories to which samples of essential oils could be classified.

Composition of the essential oils from leafy parts of the shoots, flowers and fruits of Eryngium amethystinum from Amiata Mount (Tuscany, Italy)☆
TL;DR: The essential oil of the inflorescences of Eryngium amethystinum contained much more α-pinene than the other one, while the main differences between the two essential oils can be referred to α- pinene and germacrene D.
Journal ArticleDOI
Essential oil compounds of the Annona muricata fresh fruit pulp from Cameroon
TL;DR: The essential oil of the exotic fresh fruit (pulp) Annona muricata (Annonaceae) from Cameroon was investigated by gas chromatographic/spectroscopic (GC/FID and GC/MS) and olfactoric methods to iden as discussed by the authors.

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.
