Composition of the Essential Oils of Different Parts of Seseli annuum L. (Apiaceae)

Abstract

The chemical composition of the essential oils of different parts of Seseli annuum from Serbia was investigated. beta-Selinene (0-21.4 %), germacrene D (3.4-19.1 %), caryophyllene oxide (1.2-18.1 %), germacrene A (0-14.6%), alpha-selinene (0-12.4 %), beta-elemene (0-11.4 %), E-caryophyllene (3.2-10.3 %), alpha-pinene (0.6-7.5 %), vetiselinenol (0-6.3 %) and isodaucene (0-5.4 %) were dominant compounds in the analysed essential oils. The cluster analysis revealed separation of two groups of essential oils: the first group of oils from fruit, inflorescence and aerial parts in flowering phase with high beta-selinene and alpha-selinene content and the second group of oils from leaf, stem and rosette with higher caryophyllene oxide amounts. The essential oil of rosette was separated from the oils of leaf or stem and contained the highest caryophyllene oxide content while alpha-selinene and beta-selinene were completely absent.
