α-Pinene- and β-myrcene-rich volatile fruit oil of Cupressus arizonica Greene from northwest Iran
TL;DR: The chemical and percentage composition of the studied oil from cultivated C. arizonica Greene from northwest Iran was characterised by a high occurrence of α-pinene and β-myrcene, and is thus competent for use in related industries and as a favourite ornamental aromatic tree.

Essential oil of Croton ovalifolius Vahl from Venezuela.
TL;DR: The essential oil from fresh leaves of Croton ovalifolius Vahl was obtained by hydrodistillation and analyzed by gas chromatography (GC) and GC-MS as discussed by the authors.

Chemical Composition of the Essential Oils from Leaves, Flowers, Stem and Root of Phlomis olivieri Benth.
TL;DR: The essential oils obtained from the dried leaves, flowers, stem and root of Phlomis olivieri Benth were analyzed using GC and GC/MS as mentioned in this paper, and thirteen components were identified in the oil of leaf with germacrene D (58%), α-pinene (10.4%), and bicyclogermacrene (4.4%) as main constituents.

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.
