Characterization of Essential Oil and Antioxidant Activities of Some Species of Salvia in Turkey

Abstract

In this present study, the chemical composition and antioxidant activity of the essential oils of Salvia aethiopis, Salvia blepharochlaena and Salvia euphratica collected from Turkey were evaluated According to the GC-MS analyses, 20 components (representing 98.2%) were characterized in the essential oil of S. aethiopis. The major compounds of this essential oil were determined as α-copaene (18,2%), α-cubebene (12,4 %), spathulenol (12.3%), respectively. The main components of the S. blepharochlaena essential oil were determined as 1,8-cineole (26.8 %), cis-ocimene (15.3 %) and β-pinene (7.9%), respectively. Main components of S. euphratica oil were characterized as cis-sabinol (21.9 %), myrcenyl acetate (17.5 %), and 1,8 cineole (9.5 %). Antioxidant activity evaluations by β-carotene and radical scavenging assays showed that Salvia sp. essential oils prevent linoleic acid oxidation up to 19, 22, and 21%, respectively.
