Chemical Composition, Antioxidant, Antimicrobial Activities of the Essential Oil of Salvia hypargeia Fisch & Mey.

Abstract

The aim of this study was to investigate the chemical composition, antioxidant and antimicrobial activities of the essential oil of Salvia hypargeia from Turkey. According to the results of GC-EIMS analysis, the major compounds of the oil were determined as alpha-pinene (15.9 %), beta-pinene (22.3 %), pulegone (13.5 %) and beta-ylangene (17.8 %). Essential oil could not show radical scavenging effect in DPPH system. On the other hand, inhibition capacity of the essential oil against linoleic acid oxidation was measured as 21.0 %. In the case of antimicrobial activity, the most sensitive microorganism was B. subtilis which has the lowest MIC value (35.80 mu g/ml). This is followed by S. aureus and C. diphteriae (8.45 and 14.20 mu g/ml, respectively).
