Sampling flower scent for chromatographic analysis.
TL;DR: The strengths of headspace solid-phase microextraction (HS-SPME) for in vivo monitoring are emphasized with the examples of monitoring the circadian variation of Brugmansia suaveolens flower scent and of volatile aldehyde detection in flower scent using on-fiber derivatization.

The effect of triacontanol on micropropagation and on secretory system of Thymus mastichina
Daniele Fraternale,Laura Giamperi,Donata Ricci,Marco B. L. Rocchi,Loretta Guidi,Francesco Epifano,Maria Carla Marcotullio +6 more
TL;DR: A positive effect of triacontanol on the growth of micropropagated plantlets using different conditions and there was no correlation between changes in the oil yield and glandular hairs density, but the yield was dependent on the secretory stage of the glands.
Journal ArticleDOI
Influence of different drying methods on drying period, essential oil content and composition of Lippia citriodora Kunth
TL;DR: In this paper, the influence of four drying methods (shade drying, freeze drying, oven drying and vacuum drying at 40, 50 and 60°C) on the essential oil content and composition of lemon verbena (Lippia citriodora Kunth) was evaluated.

Chemical composition of anther volatiles in ranunculaceae: Genera-specific profiles in Anemone, Aquilegia, Caltha, Pulsatilla, Ranunculus, and Trollius species
Andreas Jürgens,Stefan Dötterl +1 more
TL;DR: It is shown that most species belonging to the same genus have similar chemical compositions, including aliphatic compounds, aromatics, mono- and sesquiterpenoids, and nitrogen-bearing compounds.
Journal ArticleDOI
Chemical composition, phytotoxic and antifungal activities of Pinus pinea essential oil
TL;DR: Results showed that P. pinea essential oil could be valorized as bioproduct for biocontrol of weeds and fungal plant diseases.

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.
