In the present work, Microsteam distillation -Solid phase microextraction (MSD-SPME) and hydrodistillation (HD) techniques were applied to obtain volatiles from Achillea sivasica, an endemic species from Turkey. GC-FID and GC/MS analysis revealed that 1,8-cineole (22.1%) and -pinene (9.3%) were the main constituents of the hydrodistilled flower volatiles. (Z)--Farnesene (23.9%), decanoic acid (10.1%), eudesmol (8.0%), tricosane (7.3%) and hexadecanoic acid (7.2%) were the main volatiles obtained from flowers by MSD-SPME. The leaf volatiles obtained by HD contained camphor (9.0%), -pinene (6.9%), 1,8-cineole (6.7%), -pinene (6.7%) and-bisabolol (6.6%) as the main constituents while the leaf volatiles obtained by MSD-SPME technique were rich in (E)-geranyl acetone (10
