Comparison of essential oils of endemic Salvia dichroantha Stapf collected from Konya

Abstract

In the Anatolia folk medicine, Salvia L. (Lamiaceae) species are used by many people in various villages and towns for the therapeutic value of their essential oils. Salvia dichroantha Stapf is an endemic plant of the Irano-Turanian phytogeographic region. Plant materials were collected during the flowering period from Konya Cihanbeyli (900 m) and Konya Taskent (1800 m). In this study, water-distilled essential oil of Salvia dichroantha was analyzed. The analysis was performed by using a gas chromatography (GC-FID) and gas chromatography-mass spectrometry (GC-MS) systems, simultaneously. Eight compounds were identified from the oil of Taskent representing 96.2 % of the total oil and nine compounds were identified from the oil of Cihanbeyli representing 98.3% of the total oil . The major components were found as caryophyllene oxide (38.6%), caryophyllenol I (16.7%), caryophyllenol II (15.6%) and caryophylladienol II (11.1%) for Taskent; caryophyllene oxide (65.8%), caryophyllenol II (14.3 %) for the oil of Cihanbeyli.
