Pereira, S. I.; Santos, P. A. G.; Barroso, J. G.; Figueiredo, A. C.; Pedro, L. G.; Salgueiro, L. R.; Deans, S. G.; Scheffer, J. J. C.The compositions of the essential oils isolated from the aerial parts of 11 populations of Thymus caespititius collected during the flowering phase on Pico, Faial and Graciosa (Azores) were studied by GC and GC-MS. The monoterpene fraction was dominant in all the oils analysed (55-90%) and consisted mainly of oxygen-containing compounds (44-79%). Sesquiterpenes represented an important fraction of the oils from...

Pereira, S. I.; Santos, P. A. G.; Barroso, J. G.; Figueiredo, A. C.; Pedro, L. G.; Salgueiro, L. R.; Deans, S. G.; Scheffer, J. J. C.The compositions of the essential oils obtained from ten populations of Thymus caespititius grown on S. Jorge (Azores) were studied by GC and GC-MS. All the oils analysed were dominated by their monoterpene fraction (69-91%). The sesquiterpene fraction was rather small (4-17%) and consisted mainly of oxygen-containing compounds (3-13%). Enantiomeric ratio of sabinene and [alpha]-terpineol was investigated in th...
