Essential Oil Composition of Salvia candidissima Vahl. occidentalis Hedge, S. tomentosa Miller and S. heldreichiana Boiss. Ex Bentham from Turkey

Abstract

Previous reports clearly indicate that different chemotypes of Salvia heldreichiana, S. tomentosa and S. candidissima are present. In current study we have investigated essential oil composition of Salvia candidissima ssp. occidentalis, Salvia heldreichiana from Konya and Salvia tomentosa from Eskisehir, Turkey. In GC/MS analysis 89.30 ± 1.034 % (n=3) of the S. heldreichiana oil was identified which corresponds to 83 compounds. Main components of the oil were α-pinene 9.57 ± 0.406 %, borneol 9.21 ± 0.193 % and caryophyllene oxide 7.58 ± 0.052 %. Seventy-seven compounds were identified in aerial parts essential oil of S. candidissima ssp. occidentalis that sums up to 62.00 ± 0.962 % (n=3) of the oil. Main components were hexadecanoic acid 4.73 ± 0.022 %, m-cymene 4.00 ± 0.152 % and manool oxide 3.65 ± 0.057 %. One hundred-four compounds were identified in the aerial parts essential oil of S. tomentosa which corresponds to 89.91 ± 0.444% (n=3). The main components were, α-pinene 15.25 ± 0.621 % and borneol 7.88 ± 0.273 %. Present study revealed α-pinene/borneol/caryophyllene oxide/terpinen-4-ol chemotype of S. heldreichiana, α-pinene/borneol chemotype of S. tomentosa as well as chemical composition of S. candidissima ssp. occidentalis essential oil for the first time.
