Essential oil composition of two Lallemantia species from Bibgöl-Turkey.

Abstract

The essential oil of the dried flowering aerial parts of Lallemantia iberica (M. Bieb.) Fisch. & C.A.Mey. and Lallemantia peltata Fisch. & C.A.Mey. were analyzed by means of HS-SPME/GC-MS. As a result thirty one and thirty two components were identified representing 95.1% and 94.6% of the oil of L. iberica and L. peltata, respectively. The main constituents of L. iberica were p-cymene (25.6%),-caryophyllene (12.3%) and caryophyllene oxide (16.5%); whereas -caryophyllene (15.6%), p-cymene (14.8%), caryophyllene oxide (11.9%) and germacrene D (10.4%) were the major constituents of L. peltata. With this study, chemotypes of L. iberica and L. peltata were detected p-cymene,-caryophyllene and caryophyllene oxide. In addition essential oil structure of studied samples have detected and studied plant samples were found to be rich in respect to essential oils. The results discussed natural product, renewable resources, chemotaxonomy and for uses purposes of plants.
