The essential oils of fresh leaves of Eucalyptus globulus L. (Myrtaceae), and leaves and stems of Smyrnium olusatrum L. (Apiaceae), obtained by hydrodistillation in a Clevenger-type apparatus, were analyzed by GC/MS. Twenty compounds were characterized, representing 98.3% of the essential oil of E.

The chemical composition of the essential oil of leaves of Eucalyptus procera Dehnh., cultivated in central Iran, was obtained by hydrodistillation and analysed by GC-MS. Forty-five constituents representing 99.6% of the total oil were identified. The main constituents of the oil were found to be

Terpenes associated with resistance against the gall wasp, Leptocybe invasa, in Eucalyptus grandis.

Numai utilizatorii înregistrați pot traduce articole

Leptocybe invasa is an insect pest causing gall formation on oviposited shoot tips and leaves of Eucalyptus trees leading to leaf deformation, stunting, and death in severe cases. We previously observed different constitutive and induced terpenes, plant specialized metabolites that may act as

Cultured plant cells of Eucalyptus perriniana regioselectively hydroxylated (+)- and (-)-alpha-pinenes to the corresponding (+)- and (-)-verbenols. In addition, (+)- and (-)-verbenols were converted into mono-beta-D-glucosides. On the other hand, (+)- and (-)-beta-pinenes were transformed into (+)-
