Özet

In the present work, Microsteam distillation - Solid phase microextraction (MSD-SPME) andhydrodistillation (HD) techniques were applied to obtain volatiles from Achillea sivasica, an endemic species fromTurkey. GC-FID and GC/MS analysis revealed that 1,8-cineole (22.1%) and ?-pinene (9.3%) were the mainconstituents 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 MSDSPME.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 techniquewere rich in (E)-geranyl acetone (10.5%), (E)-?-ionone (10.3%), camphor (10.2%), 1,8-cineole (9.6%),longiverbenone (7.9%), ?-eudesmol (7.5%), isopropyl myristate (6.7%) and epi-?-bisabolol (6.4%). The root volatileswere rich in longiverbenone (14.1%), (E)-geranyl acetone (9.3%), nonanol (12.1%) and decanol (12.5%). Theenantiomeric distribution of the major volatile constituents was analyzed by using different ?-cyclodextrin chiralcolumns. (1R)-(+)-?-Pinene, (1S)-(-)-?-pinene, (4R)-(+)-limonene, (1R,3S,5R)-(-)-trans-pinocarveol, (1S,2R,4S)-(-)-borneol, (2S)-(-)-?-bisabolol were detected as dominant enantiomers. The lipids extracted from the flower and leafwith Folch method and methylated with BF3 reagent contained common acids: linolenic, linoleic, hexadecanoic acids.Oleic and stearic acids were detected particularly in high amount in the flower lipids.
