Essential oil Composition of two Pimpinella L. species from Turkey.

Abstract

The essential oil aerial parts of Pimpinella kotschyana Boiss. and Pimpinella corymbosa Boiss. species growing in Bingöl, were analyzed by GC-MS technique and 24 and 25 compounds were identified representing 94.4% and 95.9% of the oil respectively. The main constituents of P. kotschyana were -caryophyllene (26.8%), -humulene (18.6%) and germacrene D (12.8%); whereas -farnesene (28.6%), -bisabolene (22.7%) and (E)-anethole (13.9%) were the major constituents of P. corymbosa. The chemotypes of P. kotschyana and P. corymbosa were determined -caryophyllene and -farnesene, respectively. Eventually with this study, essential oil contents of P. kotschyana and P. corymbosa were found to be rich and important results presented in respect to essential oil composition of these species.
