Abstract
The compositions of the essential oils of three Jordanian
Salvia species,
S. lanigera and
S. spinosa from a desert climate, and
S. syriaca from a Mediterranean habitat, were studied. All three oils are rich in monoterpene derivatives (68–73%).
S. lanigera and
S. spinosa showed a very high content of thymol, 54.9% and 68.9%, respectively. The main constituents of
S. syriaca were thymol, α-pinene and isobornyl acetate (15.5%, 12.6% and 12.0%, respectively).
