ANTIOXIDANT ACTIVITY AND CHEMICAL COMPOSITION OF THE ESSENTIAL OIL OF SALVIA CANDIDISSIMA VAHL. GROWNIG WILD IN TURKEY

The chemical constituents of the essential oil from aerial parts of Salvia candidissima Vahl., collected in Turkey, were analyzed by GC and GC/MS. The oil yield of the dried plant obtained by hydrodistillation was 0.7% (v/w). 70 compounds, accounting for 99.65% of the oil, were identified.
The major constituents were camphor (28.94%), bornyl acetate (12.80%), borneole (9.44%), ß-cadinene (5.88%), -caryophyllene (5.40%), 1,8-cineole (5.15%), ß-pinene (4.93%) and -pinene (4.89%). In addition, the antioxidant properties of essential oil and hexane, ethyl acetate and ethanol extracts of S. candidissima Vahl. were examined.
The antioxidant activity was investigated with two different methods: ß-carotene bleaching test and the 2,2’-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging method. ß-carotene bleaching test shows that the most active extract which were achieved by us were ethanol extract (95,70%) from S. candidissima (94,5%). In DPPH free radical scavenging activities, the ethanol extract (94,55%) and hexane extract (83,21%) were showed high activity, respectively.
