Essential Oil Composition of Three Globularia Species

The chemical composition of the essential oils obtained by hydrodistillation from aerial parts of Globularia cordifolia L., G. meridionalis (Podp.) O. Schwarz and G. punctata Lapeyr. was characterized by GC/FID and GC/MS analyses. Among 33 identified compounds, the most abundant present in all investigated samples were oct-1-en-3-ol (2.9-47.0%), 6-(1, 5- dimethylhex-4-enyl)-3- methylcyclohex-2-enone (8.2-40.9%) and fukinanolid (7.4-31.6%). The multivariate statistical analyses (PCA and HCA) of the hitherto studied Globularia volatile compounds confirm to some extent the assumed phylogenetic relationships of the Globularia species studied, including the close relationship between morphologically similar G. cordifolia and G. meridionalis, but also evidenced several discrepancies in current classification of Globularia species.
