The chemical composition of the aerial parts essential oil of Ferulago nodosa (L.) Boiss. (Apiaceae) growing wild in Crete (Greece)
2023
Ferulago nodosa (L.) Boiss. (Apiaceae) is a species occurring in the Balkan-Tyrrhenian area being present in Crete, Greece, Albania, and probably in Macedonia. Although the western disjointed population of Sicily has been classified as an endemic sub-species, F. nodosa subsp. geniculata (Guss.) Troia & Raimondo, its official acceptance is quite controversial. In order to verify the existence of two different sub-species, we investigated the chemical composition of the essential oil of F. nodosa, collected in Crete (Greece), not previously reported, and we compared it with the previously oil compositions reported in literature. Main constituents of the Cretan accessions of F. nodosa were…

The essential oils of the flowers of Magydaris tomentosa (Desf.) DC. (Apiaceae) collected in Sicily (MSi) and Algeria (MAl), respectively, were obtained by hydrodistillation, and their compositions were analysed. The analyses allowed the identification and quantification of 23 components in MSi and 60 compounds in MAl, respectively, showing a very different profile in the composition of the two populations. The main components of MSi were cembrene (28.2%), α-springene (17.5%) and β-springene (14.8%), also present in MAl but in lesser amount (0.4%, 1.8% and 0.9%, respectively), whereas the principal constituents of MAl were (E)-nerolidol (35.4%), α-costol (13.3%) and β-costol (6.8%). Both MS…
