Abstract The chemical composition of the essential oils obtained from the flowers and leaves of Salvia sclarea L. (Lamiaceae) cultivated in Slovak Republic have been studied by GC and GC/MS methods, which resulted in the identification of 34 and 23 components, respectively. The major constituents in the flower oil were linalool (18.9%), linalyl acetate (13.7%), sclareol (15.7%), Î±-terpineol (6.5%), germacrene D (5.0%) and geranyl acetate (4.3%), while the major components in the leaf oil were germacrene D (28.8%), bicyclogermacrene (12.5%), spathulenol (10.1%), caryophyl-lene oxide (6.2%) and Î±-copaene (6.0%).
