Composition of the essential oils ofPelargonium odoratissimum,P. exstipulatum, andP. � fragrans (Geraniaceae) and their bioactivity

The volatile oils of the leaves of two Pelargonium species, P. exstipulatum (Cav.) L'Herit. and P. odoratissimum (L.) L'Herit. (Geraniaceae) and a hybrid, P. × fragrans, were obtained by steam distillation and the chemical components were identified by capillary GC and GC–MS. Methyl eugenol was high in P. odoratissimum and P. × fragrans; fenchone and limonene was common in all three, whilst thujene and α-pinene were high in P. exstipulatum and...
