Essential oils composition of two Sicilian cultivars of Opuntia ficus-indica (L.) Mill. (Cactaceae) fruits (prickly pear)
TL;DR: Several compounds identified in this study have been reported to influence the behaviour of Ceratitis capitata, a phytophagous pest which causes severe damages to several crops including O. ficus-indica and the kairomonal activity of the odour of the fruits seems provided by a blend of compounds found in the various matrices analysed.

Ecophysiological and phytochemical responses of Salvia sinaloensis Fern. to drought stress
Matteo Caser,Francesca D'Angiolillo,Walter Chitarra,Walter Chitarra,Walter Chitarra,Claudio Lovisolo,Barbara Ruffoni,Luisa Pistelli,Laura Pistelli,Valentina Scariot +9 more
TL;DR: Findings point at S. sinaloensis as a potential drought adaptive species, which could be used in breeding strategies to obtain sages with high quality PSMs, saving irrigation water.

Chemical composition of the essential oil of different varieties of thyme (Thymus pulegioides) growing wild in Lithuania
TL;DR: There is no clear relation in essential oil composition between the studied taxa and the chemical types detected, followed by the phenolic types, the linalool chemotype being recorded only once.

Ashok Pandey,Ashim R. Chowdhury +1 more
TL;DR: The volatile rhizomes oil of Curcuma caesia was analyzed by GC-MS, which resulted in the identification of 30 components, representing 97.48% of the oil 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.
