Essential oil composition of endemic Pimpinella tunceliana Yıld. from Turkey for the first time

Abstract

The objective of this study was to examine the essential oil of Pimpinella tunceliana Yıld. growing wild in the Eastern part of Turkey for the first time. Obtained results were discussed with the genus patterns and natural products. The essential oil of P. tunceliana was analyzed by head space-solid phase microextraction (HS-SPME)/gas chromatography-mass spectrometry (GC-MS) technique, and 50 compounds were identified, representing 96.3% of the oil. The main constituents of P. tunceliana were β-caryophyllene (13.9%), β-bisabolene (10.4%), anethole (9.3%), sabinene (7.5%), limonene (6.9%) and germacrene D (6.8%). In this study, essential oil contents of P. tunceliana that is a new and endemic species was studied for the first time, and important results were presented in respect to the composition of the oil of this new species of Pimpinella.
