Evaluation and optimization of the automatic thermal desorption method in the gas chromatographic determination of plant volatile compounds
TL;DR: In this article, the automatic thermal desorption (ATD) method was used in the gas chromatographic determination of the volatile components of plants and the reproducibility of the method was evaluated for several operating conditions; the results were better than those obtained with other sample preparation methods.

Analysis of the oil of Heracleum persicum L. (leaves and flowers).
TL;DR: The chemical composition of the essential oils obtained by hydrodistillation of the leaves (before and at full flowering stage) and flowers of Heracleum persicum L. were investigated by a combination of GC and GC/MS as mentioned in this paper.

Giulia Giunti,Davide Palermo,Francesca Laudani,Giuseppe M. Algeri,Orlando Campolo,Vincenzo Palmeri +5 more
TL;DR: The developed nano-formulation showed acute toxicity against both insects when tested as fumigant and cold aerosol and was effective in controlling and repelling the target pests.
Journal ArticleDOI
Essential oil composition of Teucrium scordium L.
TL;DR: The essential oil obtained from dried flowering aerial parts of Teucrium scordium L. (Labiatae) was analyzed by GC and GC/MS and fifty-six components were identified in the essential oil.

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.
