Chemical Composition of the Essential Oils of Wild Helichrysum arenarium (L.) with Differently Colored Inflorescences from Eastern Lithuania

摘要

Essential oil composition of Helichrysum arenarium (L.) Moench.of natural populations from eastern Lithuania has been studied.Samples of leaves and inflorescences of different colors [yellow and orange (f.aurantiacum (Pers.) Bleck.)] were collected from the same growing localities at flowering stage.The oils were prepared by hydrodistillation and analyzed by GC and GC/MS.The 68 constituents identified comprised 73.8-90.7% of the total oil content.It was found that the principal constituents were: beta-caryophyllene (in three inflorescence and one leaf oil),delta-cadinene (in two leaf oils),octadecane (in one leaf oil) and heneicosane (in one inflorescence sample).Monoterpenes and oxygenated monoterpenes made up 4.0-13.9%,aliphatic hydrocarbons 0.4-35.3%,and sesquiterpenes 24.7-71.2% of the oils.
