Essential oils composition of two endemic umbelliferae herbs growing wild in Turkey

Abstract

The present study was carried out to determine the essential oil composition of aerial parts of two endemic umbelliferae herbs (Malabaila lasiocarpa Boiss. and Stenotaenia macrocarpa Freyn & Sint. ex Freyn) collected from Bingol (Turkey), using headspace solid-phase microextraction method and gas chromatography (GC) interfaced with mass spectrometer analysis. Forty six and forty three compounds were identified for M. lasiocarpa and S. macrocarpa, respectively, representing 91.40% and 90.86% of their respective essential oils. Germacrene D (20.71%), -elemene (12.40%), spathulenol (11.60%) and -selinene (9.67%) were identified as the major compound of M. lasiocarpa. -sesquiphellandrene (19.68%), hexyl isobutyrate (12.65%) and octanal (9.53%) were found to be the major compounds of S. macrocarpa. Essential oil composition of M. lasiocarpa has been determined for the first time and the results have been discussed in view of chemotaxonomy, natural products and potential usefulness of these plants.
