Original Title:
Μελέτη γεωγραφικής και υψομετρικής διακύμανσης πτητικών μεταβολιτών σε φυτικά μέρη της Κεφαλληνιακής ελάτης (Abies cephalonica)
Translated title:
Investigation of the geographic and altitudinal variation of volatile metabolites in plant parts of the Greek fir (Abies cephalonica)
Summary:
In the framework of the present study the chemical composition of the essential oils of Abies cephalonica leaves and twigs was investigated. The plant material was collected from Mt. Ainos, Mt. Parnitha and Mt. Dirfi, in western and central Greece, and three different altitudes of each area. In total 36 samples were collected and the fresh leaves and twigs were subjected separately to hydrodistillation. The obtained essential oils were analyzed by gas chromatography-mass spectrometry (GC/MS). Comparative analysis of the essential oils showed only a few quantitative variations, mainly between the samples collected from different geographic areas. Overall, monoterpene hydrocarbons dominated both foliage and twig oil. β-Pinene was the major component in the leaf oils, followed by limonene/β-phellandrene and α-pinene, while limonene characterized the twig oils, followed by α-pinene and β-pinene. No recurring pattern was observed among the essential oils originating from different altitudes of the same area, thus no clear influence of this parameter on the chemical profile of foliage or twig oils could be attributed.
