Volatile components of Ferulago aucheri Boiss. (Apiaceae)

Ferulago aucheri Boiss, which belongs to the Apiaceae family, is distributed from Türkiye to the Caucasus. Its chemical composition may vary depending on the region where it grows, climate conditions and topography. Essential oil components were determined using two different techniques (hydrodistilled and headspace-solid phase microextraction HS-SPME) with the species collected from Nallıhan district of Ankara, Türkiye. In the present study, essential oil and headspace volatiles of aerial parts of Ferulago aucheri Boiss. were analyzed by GC-GC/MS. Thirty-five components were characterized, representing 99.6% of the oil by hydrodistilled and thirty components were characterized, representing 98.7% by HS-SPME. In both techniques, the main substances were identified as α-pinene, limonene, and δ-3-carene. In previous studies, it has been observed that the main components are in different amounts, and some studies even have different main components.
